Faster, Smoother, More Responsive Android 4.
For a graphics performance boost, the hardware-accelerated 2D renderer now optimizes the stream of drawing commands, transforming it into a more efficient GPU format by rearranging and merging draw operations.
For multithreaded processing, the renderer can also now use multithreading across multiple CPU cores to perform certain tasks.
Shapes such as circles and rounded rectangles are now rendered at higher quality in a more efficient manner.
Optimizations for text include increased performance when using multiple fonts or complex glyph sets CJKhigher rendering quality when scaling text, and faster rendering of drop shadows.
Improved window buffer allocation results in a faster image buffer allocation for your money android games apk, reducing the time taken to start rendering when you create a window.
For highest-performance graphics, Android 4.
On supported devices, the hardware accelerated 2D rendering engine takes advantage of OpenGL ES 3.
You can take advantage of OpenGL ES 3.
Key new functionality provided in OpenGL ES 3.
You can use the OpenGL ES 3.
Support is already available on Nexus 7 2013Nexus 4, and Nexus 10 devices.
Enhanced Bluetooth Connectivity Connectivity with Bluetooth Smart devices and sensors Now you can design and build apps that interact with the latest generation of small, low-power devices and sensors that use.
With the new APIs, your apps can efficiently scan for devices and services of interest.
For each device, you can check for supported GATT services by UUID and manage connections by device ID and signal strength.
You can connect to click the following article GATT server hosted on the device and read or write characteristics, or register a listener to receive notifications whenever those characteristics change.
You can implement support for any GATT profile.
You can read or write standard characteristics or add support for custom characteristics as needed.
Your app can function as either client or server and can transmit and receive data in either mode.
Support for Bluetooth Smart Ready is already available on Nexus 7 2013 and Nexus 4 devices and will be supported in a growing number of Android-compatible devices in the months ahead.
Apps such as media players can take advantage of AVRCP 1.
In addition to exposing playback controls on the remote devices connected over Bluetooth, apps can now transmit metadata such as track name, composer, and other types of media metadata.
Platform support for AVRCP 1.
Support for Restricted Profiles A tablet owner can set up one or more restricted profiles in Settings and manage them independently.
Your app can offer restrictions to let owners manage your app content when it's running in a profile.
With restricted profiles, tablet owners can quickly set up separate environments for each user, with the ability to manage finer-grained restrictions in the apps that are available in those environments.
Restricted profiles are ideal for friends and family, guest users, kiosks, point-of-sale devices, and more.
Each restricted profile offers an isolated and secure space with its own local storage, home screens, widgets, and settings.
For developers, restricted profiles offer a new way to deliver more value and control to your users.
You can implement app restrictions — content or capabilities controls that are supported by your app — and advertise them to tablet owners in the profile configuration settings.
You can add app restrictions directly to the profile configuration settings using predefined boolean, select, and multi-select types.
If you want more flexibility, you can even launch your own UI from profile configuration settings to offer any type of restriction you want.
When your app runs in a profile, it can check for any restrictions configured by the owner and enforce them appropriately.
For example, a media app might offer a restriction to let the owner set a maturity level for the profile.
At run time, the app could check for the maturity setting and then manage content according to the preferred maturity level.
If your app is not designed for use in restricted profiles, you can opt out altogether, so that your app can't be enabled in any restricted profile.
Optimized Location and Sensor Capabilities offers advanced location APIs that you can use in your apps.
Hardware geofencing optimizes for power efficiency by performing location computation in the device hardware, rather than in software.
On devices that support hardware geofencing, Google Play services geofence APIs will be able to take advantage of this optimization to save battery while the device is moving.
Wi-Fi scan-only mode is a new platform optimization that lets users keep Wi-Fi scan on without connecting to a Wi-Fi network, to improve location accuracy while conserving battery.
Apps that depend on Wi-Fi for location services can now ask users to enable scan-only mode from Wi-Fi advanced settings.
Wi-Fi scan-only mode is not dependent on device hardware and is available as part of the Android 4.
New sensor types allow apps to better manage sensor readings.
Uncalibrated gyroscope and uncalibrated magnetometer sensors report raw measurements as well as estimated biases to apps.
The new hardware capabilities are already available on Nexus 7 2013 and Nexus 4 devices, and any device manufacturer or chipset vendor can build them into their devices.
New Media Capabilities Modular DRM framework To meet the needs of the next generation of media services, Android 4.
Through a combination of new APIs and enhancements to existing APIs, the media DRM framework provides an integrated set of services for managing licensing and provisioning, accessing low-level codecs, and decoding encrypted media data.
A new MediaExtractor API lets you get the PSSH metadata for DASH media.
Apps using the media DRM framework manage the network communication with a license server and handle the streaming of encrypted data from a content library.
VP8 encoder Android 4.
For apps using native APIs, the platform includes OpenMAX 1.
VP8 encoding learn more here includes settings for target bitrate, rate control, frame rate, token partitioning, error resilience, reconstruction and loop filters.
The platform API introduces VP8 encoder support in a range of formats, so you can take advantage of the best format for your content.
VP8 encoding is available in software on all compatible devices running Android 4.
For highest performance, the platform also supports hardware-accelerated VP8 encoding on capable devices.
Video encoding from a surface Starting in Android 4.
For example, you can now direct a stream from an OpenGL ES surface to the encoder, rather than having to copy between buffers.
Media muxer Apps can use new media muxer APIs to combine elementary audio and video streams into a single output file.
Currently apps can multiplex a single MPEG-4 audio stream and a single MPEG-4 video stream into a single MPEG-4 output file.
The new APIs are a counterpart to the media demuxing APIs introduced in Android 4.
Playback progress and scrubbing in remote control clients Since Android 4.
Starting in Android 4.
New Ways to Build Beautiful Apps Access to notifications Notifications have long been a popular Android feature because they let users see information and updates from across the system, all in one place.
Now in Android 4.
You can access notifications through new APIs that let you register a notification listener service and with permission of the user, receive notifications as they are displayed in the status bar.
Notifications are delivered to you in full, with all details on the originating app, the post time, the content view and style, and priority.
You can evaluate fields of interest in the notifications, process or add context from your app, and route them for display in any way you choose.
The new API gives you callbacks when a notification is added, updated, and removed either because the user dismissed it or the originating app withdrew it.
You'll be able to launch any intents attached to the notification or its actions, as well as dismiss it from the system, allowing your app to provide a complete user interface to notifications.
Users remain in control of which apps can receive notifications.
At any time, they can look in Settings to see which apps have notification access and enable or disable access as needed.
Notification access is disabled by default — apps can use a new Intent to take the user directly to the Settings to enable the listener service after installation.
View overlays You can now create transparent overlays on top of Views and ViewGroups to render a temporary View hierarchy or transient animation effects without disturbing the underlying layout hierarchy.
Overlays are particularly useful when you want to create animations such as sliding a view outside of its container or dragging items on the screen without affecting the view hierarchy.
Optical bounds layout mode A new layout mode lets you manage the positioning of Views inside ViewGroups according to their optical bounds, rather than their clip bounds.
You can use the optical bounds layout mode to properly align widgets that use outer visual effects such as shadows and glows.
Custom rotation animation types Apps can now define the exit and entry animation types used on a window when the device is rotated.
You can set window properties to enable jump-cut, cross-fade, or standard window rotation.
The system uses the custom animation types when the window is fullscreen and is not covered by other windows.
Screen orientation modes Apps can set new orientation modes for Activities to ensure that they are displayed in the proper orientation when the device is flipped.
Additionally, apps can use a new mode to lock the screen to its current orientation.
This is useful for apps using the camera that want to disable rotation while shooting video.
Intent for handling Quick Responses Android 4.
Your app can listen for the intent and send the message to the caller over your messaging system.
The intent includes the recipient caller as well as the message itself.
Support for International Users More parts of Android 4.
RTL improvements Android 4.
More debugging information visible through the uiautomatorviewer tool.
In addition, more system UI components are now RTL aware, such as notifications, navigation bar and the Action Bar.
To provide a better systemwide experience in RTL scripts, more default system apps now online casino android deposit RTL layouts, including Launcher, Quick Settings, Phone, People, SetupWizard, Clock, Downloads, and more.
Utilities for localization Pseudo-locales make it easier to test your app's localization.
A new BidiFormatter class provides a simple API for wrapping Unicode strings, so that RTL-script data is displayed as intended in LTR-locale messages and vice-versa.
To let you use this utility more broadly in your apps, the BidiFormatter API is also now available for earlier platform versions through the Support Package in the Android SDK.
To assist you with managing date formatting across locales, Android 4.
To help you test your app more easily in other locales, Android 4.
Pseudo-locales simulate the language, script, and display characteristics associated with a locale or language group.
Currently, you can test with a pseudo-locale for Accented English, which lets you see how your UI works with script accents and characters used in a variety of European languages.
Accessibility and UI Automation Starting in Android 4.
The service receives the events and can process them as needed before they are passed to the system or other installed apps.
Accessibility services can declare new capability attributes to describe what their services can do and what platform features they use.
For example, they can declare the capability to filter key events, retrieve window content, enable explore-by-touch, or enable web accessibility features.
In some cases, services must declare a capability attribute before they can access related platform features.
Building on the accessibility framework in Android 4.
Through the UI automation framework you can perform basic operations, set rotation of the screen, generate input events, take screenshots, and much more.
Enterprise and Security Wi-Fi configuration for WPA2-Enterprise networks Apps can now configure the Wi-Fi credentials they need for connections to WPA2 enterprise access points.
Developers can use new APIs to configure Extensible Authentication Protocol EAP and Encapsulated EAP Phase 2 credentials for authentication methods used in the enterprise.
Apps with permission to access and change Wi-Fi can configure authentication credentials for a variety of EAP and Phase 2 authentication methods.
Android sandbox reinforced with SELinux Android now uses SELinux, a mandatory access control MAC system in the Linux kernel to augment the UID based application sandbox.
This protects the operating system against potential security vulnerabilities.
KeyChain enhancements The KeyChain API now provides a method that allows applications to confirm that system-wide keys are bound to a hardware root of trust for the device.
This provides a place to create or store private keys that cannot be exported off the device, even in the event of a root or kernel compromise.
Android Keystore Provider Android 4.
Using the APIs, apps can create or store private keys that cannot be seen or used by other apps, and can be added to the keystore without any user interaction.
The keystore provider provides the same security benefits that the KeyChain API provides for system-wide credentials, such as binding credentials to a device.
Private keys in the keystore cannot be exported off the device.
This reduces root attack surface and likelihood of potential security vulnerabilities.
New Ways to Analyze Performance Systrace uses a new command syntax and lets you collect more types of profiling data.
Enhanced Systrace logging Android 4.
You can now collect trace data from hardware modules, kernel functions, Dalvik VM including garbage collection, resources loading, and more.
There's minimal impact on the performance of your app, so timings reported give you an accurate view of what your app is doing.
You can visualize app-specific events in a timeline in the Systrace output file and analyze the events in the context of other kernel and user space trace data.
Together with existing Systrace tags, custom app sections can give you new ways to understand the performance and behavior of your apps.
On-screen GPU profiling in Android 4.
On-screen GPU profiling Android 4.
You can choose to display profiling data as on-screen bar or line graphs, with colors indicating time spent creating drawing commands blueissuing the commands orangeand waiting for the commands to complete yellow.
The system updates the on-screen graphs continuously, displaying a graph for each visible Activity, including the navigation bar and notification bar.
If you see operations that cross the green line, you can analyze them further using Systrace and other tools.
On devices running Android 4.
This new policy helps you catch and fix such cases.
This document provides a glimpse of what's new for developers.
See the document for a detailed look at the new developer APIs.
Find out more about the new Jelly Bean features for users at.
Faster, Smoother, More Responsive Android 4.
Improvements in the hardware-accelerated 2D renderer make common animations such as scrolling and swiping smoother and faster.
In particular, drawing is optimized for layers, clipping and certain shapes rounded rects, circles and ovals.
A variety of WebView rendering optimizations make scrolling of web pages smoother and free from jitter and lags.
It automatically takes advantage of GPU computation resources whenever possible, dramatically improving performance for graphics and image processing.
Any app using Renderscript on a supported device can benefit immediately from this GPU integration without recompiling.
Refined, refreshed UI Android 4.
All screen sizes now feature the status bar on top, with pull-down access to notifications and a new Quick Settings menu.
The familiar system bar appears on the bottom, with buttons easily accessible from either hand.
The Application Tray is also available on all screen sizes.
One tablet, many users Now several users can share a single Android tablet, with each user having convenient access to a dedicated user space.
Users can switch to their spaces with a single touch from the lock screen.
On a multiuser device, Android gives each user a separate environment, including user-specific emulated SD card storage.
Users also have their own homescreens, widgets, accounts, settings, files, and apps, and the system keeps these separate.
All users share core system services, but the system ensures that each user's applications and data remain isolated.
In effect, each of the multiple users has their own Android device.
Users can install and uninstall code android jelly bean at any time in their own environments.
To save storage space, Google Play downloads an APK only if it's not already installed by another user on the device.
If the app is already installed, Google Play records the new user's installation in the usual way but doesn't download another copy of the app.
Multiple users can run the same copy of an APK because the system creates a new instance for each user, including a user-specific data directory.
For developers, multi-user support is transparent — your apps do not need to do anything special to run normally in a multi-user environment and there are no changes you need to make in your existing or published APKs.
The system manages your app in each user space just as it does in a single-user environment.
New ways to engage users You can extend app widgets to run on the lock screen, for instant access to your content.
Lock screen widgets In Android 4.
Users can add as many as five lock screen widgets, choosing from widgets provided by installed apps.
The lock screen displays each widget in its own panel, letting users swipe left and right to view different panels and their widgets.
Like all app widgets, lock screen widgets can display any kind of content and android source code can accept direct user interaction.
They can be entirely self-contained, such as a widget that offers controls to play music, or they can let users jump straight to an Activity in your app, after unlocking along the way as needed.
For developers, lock screen widgets offer a great new way to engage users.
You can take advantage of this new capability by building a new app widget or by extending an existing home screen widget.
If your app already includes home screen widgets, you can extend them to the lock screen with minimal change.
To give users an optimal experience, you can update the widget to use the full lock screen area when available and resize when needed on smaller screens.
You can also add features to your widgets that might be especially useful or convenient on the lock screen.
In this mode, the system launches a daydream — a remote content service provided by an installed app — as the device screensaver.
A user can enable Daydream from the Settings app and then choose the daydream to display.
Daydreams combine the best capabilities of live wallpapers and home screen widgets, but they are more powerful.
They let you offer the any kind of content in a completely new context, with user interactions such as flipping through photos, playing audio or video, or jumping straight into your app with a single touch.
Because authoritative iron man bonus code android sorry can start automatically when a device is charging or docked, they also give your app a great way to support new types of user experiences, such as leanback or exhibition mode, demo or kiosk mode, and "attract mode" — all without requiring special hardware.
Daydream lets you create powerful interactive screensavers that display any kind of content.
Daydreams are similar to Activities and can do anything that Activity can do — from rendering a UI hierarchy without using RemoteViews to drawing directly using Canvas, OpenGL, SurfaceTexture, and more.
They can play video and audio and they can even accept direct user interaction.
You can provide multiple daydreams in your app and you can offer distinct content and display settings for each.
External display support Android 4.
Apps can build on this to deliver new kinds of interaction and entertainment experiences to users.
Display manager Apps interact with displays through a new display manager system service.
Your app can enumerate the displays and check the capabilities of each, including size, density, display name, ID, support for secure video, and more.
Your app can also receive callbacks when displays are added or removed or when their capabilities change, to better manage your content on external displays.
Your app just gives the display to use, a theme for the window, and any unique content to show.
The Presentation handles inflating resources and rendering your content according to the characteristics of the targeted display.
You can take full control of two or more independent displays using Presentation.
A Presentation gives your app full control over the remote display window and its content and lets you manage it based on user input events such as key presses, gestures, motion events, and more.
You can use all of the normal tools to create a UI and render content in the Presentation, from building an arbitrary view hierarchy to using SurfaceView or SurfaceTexture to draw directly into the window for streamed content or camera previews.
Preferred display selection When multiple external displays are available, you can create as many Presentations as you need, with each one showing unique content on a specific display.
For this, the system can help your app choose the best display to use.
Alternatively, you can use the media router service, extended in Android 4.
Your app can display content by default in the main Activity until a preferred Presentation display is attached, at which time it can automatically switch to Presentation content on the preferred display.
Protected content For apps that handle protected or encrypted content, the display API now reports the secure video capabilities of attached displays.
Your app query a display to find out if it offers a secure video output or provides protected graphics buffers and then choose the appropriate content stream or decoding to make the content viewable.
For additional security on SurfaceView objects, your app can set a secure flag to indicate that the contents https://m2g.info/android/lets-vegas-casino-slot-roulette-android.html never appear in screenshots or on a non-secure display output, even when mirrored.
Wireless display Starting in Android 4.
When a wireless display is connected, users can stream any type of content to the big screen, including photos, games, maps, and more.
Apps can take advantage of wireless displays in the same way as they do other external displays and no extra work is needed.
The system manages the network connection and streams your Presentation or other app content to the wireless display as needed.
Native RTL support Developers can now mirror their layouts for RTL languages.
With native RTL support, you can deliver the same great app experience to all of your users, whether their language uses a script that reads right-to-left or one that reads left-to-right.
When the user switches the system language to a right-to-left script, the system now play games for prizes and money automatic mirroring of app UI layouts and all view widgets, in addition to bidi mirroring of text elements for both reading and character input.
Your app can take advantage of RTL layout mirroring in your app with minimal effort.
The system then handles the mirroring and display of your UI as appropriate.
For precise control over your app UI, Android 4.
You can even create custom versions of layout, drawables, and other resources for display when a right-to-left script is in use.
Enhancements for international languages Android 4.
For any Fragment, a new Fragment manager lets you insert other Fragments as child nodes in the View hierarchy.
You can use nested Fragments in a variety of ways, but they are especially useful for implementing dynamic and reusable UI components inside of a UI component that is itself dynamic and reusable.
For example, if you use ViewPager to create fragments that swipe left and right, you can click at this page insert fragments into each Fragment of the view pager.
To let you take advantage of nested Fragments more broadly in your app, this capability is added to the latest version of the Android Support Library.
Accessibility The system now helps accessibility services distinguish between touch exploration and accessibility gestures while in touch-exploration mode.
When a user touches the screen, the system notifies the service that a generic touch interaction has started.
It then tracks the speed of the touch interaction and determines whether it is a touch exploration slow or accessibility gesture fast and notifies the service.
When the touch interaction ends, the system notifies the service.
The system provides a new global accessibility option that lets an accessibility service open the Quick Settings menu based on an action by the user.
Also added in Android 4.
To give accessibility services insight into the meaning of Views for accessibility purposes, the framework provides new APIs for associating a View as the label for another View.
The label for each View is available to accessibility services through AccessibilityNodeInfo.
Improved Camera with HDR Android 4.
On supported devices, apps can use a new HDR camera scene mode to capture an image using high dynamic range imaging techniques.
Additionally, the framework now provides an API to let apps check whether the camera shutter sound can be disabled.
Apps can then let the user disable the sound or choose an alternative sound in place of the standard shutter sound, which is recommended.
Renderscript Computation In Android 4.
Filterscript Filterscript is a subset of Renderscript that is focused on optimized image processing across a broad range of device chipsets.
Developers can write their image processing operations in Filterscript using the standard Renderscript runtime API, but within stricter constraints that ensure wider compatibility and improved optimization across CPUs, GPUs, and DSPs.
Filterscript is ideal for hardware-accelerating simple image-processing and computation operations such as those that might be written for OpenGL ES fragment shaders.
Because it places a relaxed set of constraints on hardware, your operations are optimized and accelerated on more types of device chipsets.
Any app targeting API level 17 or higher can make use of Filterscript.
Script intrinsics In Android 4.
Intrinsics are available for blends, blur, color matrix, 3x3 and 5x5 convolve, per-channel lookup table, and converting an Android YUV buffer to RGB.
Script groups You can now create groups of Renderscript scripts and execute them all with a single call as though they were part of a single script.
This allows Renderscript to optimize execution of the scripts in ways that it could not do if the scripts were executed individually.
Renderscript image-processing benchmarks run on different Android platform versions Android please click for source />Renderscript image-processing benchmarks comparing operations run with GPU + CPU to those run in CPU only on the same Nexus 10 device.
If you have a directed acyclic graph of Renderscript operations to run, you can use a builder class to create a script group defining the operations.
At execution time, Renderscript optimizes the run order and the connections between these operations for best performance.
Ongoing optimization improvements When you use Renderscript for computation operations, you apps benefit from ongoing performance and optimization improvements in the Renderscript engine itself, without any impact on your app code or any need for recompilation.
As optimization improves, your operations execute faster and on more chipsets, without any work on your part.
The chart at right highlights the performance gain delivered by ongoing Renderscript optimization improvements across successive versions of the Android platform.
GPU Compute Renderscript Compute is the first computation platform ported to run directly on a mobile device GPU.
It now automatically takes advantage of GPU computation resources whenver possible to improve performance.
With GPU integration, even the most complex computations for graphics or image processing can execute with dramatically improved performance.
Any app using Renderscript on a supported device can benefit immediately from this GPU integration, without recompiling.
The Nexus 10 tablet is the first device to support this integration.
New built-in developer options The Android 4.
The new options expose features for debugging and profiling your app from any device or emulator.
On devices running Android 4.
New developer options give you more ways to profile and debug on a device.
New developer options in Android 4.
This can speed up the development process while keeping the security feature enabled.
New Platform Technologies Android 4.
In most cases, the new platform technologies and enhancements do not directly affect your apps, so you can benefit from them without any modification.
Security enhancements Every Android release includes dozens of security enhancements to protect users.
Here are some of the enhancements in Android 4.
App verification can alert the user if they try to install an app that might be harmful; if an application is especially bad, it can block installation.
The user can choose whether to allow the application to send the message or block it.
This prevents applications from sending data across other networks.
Pinned domains will receive a certificate validation failure if the certificate does not chain to a set of expected certificates.
This protects against possible compromise of Certificate Authorities.
During review of the permissions, the user can click on the permission to see more detailed information about the permission.
This is used by system libraries and applications to prevent memory corruption.
RSA to use OpenSSL.
Added SSLSocket support for TLSv1.
To improve security, some devices with earlier versions of Android may also include these fixes.
New Bluetooth stack Android 4.
The new Bluetooth stack developed in collaboration between Google and Broadcom replaces the stack based on BlueZ and provides improved compatibility and reliability.
Low-latency audio Android 4.
These improvements depend on hardware support — devices that offer these low-latency audio features can advertise their support to apps through a hardware feature constant.
New AudioManager APIs are provided to query the native audio sample rate and buffer size, for use on devices which application android source code this feature.
New camera hardware interface Android 4.
The camera subsystem includes the implementations for components in the camera pipeline such as burst mode capture with processing controls.
New NFC hardware interface and controller interface Android 4.
NCI provides a standard communication protocol between an NFC Controller NFCC and https://m2g.info/android/android-apps-no-code.html device Host, and the new NFC stack developed in collaboration between Google and Broadcom supports it.
This document provides a glimpse of what's new for developers.

Faster, Smoother, More Responsive Android 4.
To ensure a consistent framerate, Android 4.
This results in a more reactive and uniform touch response.
Tooling can help you get the absolute best performance out of your apps.
The data is represented as a group of vertically stacked time series graphs, to help isolate rendering interruptions and other issues.
The tool is available now in the Tools R20 or higher Enhanced Accessibility New APIs for accessibility services let you handle gestures and manage accessibility focus as the user moves through the on-screen elements and navigation buttons using accessibility gestures, accessories, and other input.
The Talkback system and explore-by-touch are redesigned to use accessibility focus for easier use and offer a complete set of APIs for developers.
Accessibility services can link their own tutorials into the Accessibility settings, to help users configure and use their services.
Apps that use standard View components inherit support for the new accessibility features automatically, without any changes in their code.
Apps that use custom Views can use new accessibility node APIs to indicate the parts of the View that are of interest to accessibility services.
Bi-Directional Text and Other Language Support Android 4.
Apps can display text or handle text editing in left-to-right or right-to-left scripts.
Apps can make use of new Arabic and Hebrew locales and associated fonts.
By default, Android 4.
When users connect a keyboard, they can go to the Settings app and select one or more keymaps that they want to use for that keyboard.
When typing, users can switch between keymaps using a shortcut ctrl-space.
You can create an app to publish additional keymaps to the system.
The APK would include the keyboard layout resources in it, based on standard Android keymap format.
New Ways to Create Beautiful UI Developers can create custom notification styles like those shown in the examples above to display rich content and actions.
Expandable notifications Notifications have long been a unique and popular feature on Android.
Apps can now display larger, richer notifications to users that can be expanded and collapsed with a pinch or swipe.
Notifications support new types of content, including photos, have configurable priority, and can even include multiple actions.
Through an improved notification builder, apps can create notifications that use a larger area, up to 256 dp in height.
In addition to the templated styles, you can create your own notification styles using any remote View.
Apps can add up to three actions to a notification, which are displayed below the notification content.
The actions let the users respond directly to the information in the notification in alternative ways.
With expandable notifications, apps can give more information to the user, effortlessly and on demand.
Users remain in control and can long-press any notification to get information about the sender and optionally disable further notifications from the app.
App Widgets can resize automatically to fit the home screen and load different content as their sizes change.
Resizable app widgets Android 4.
New App Widget APIs let you take advantage of this to optimize your app widget content as the size of widgets changes.
For example, a widget could display larger, richer graphics or additional functionality or options.
Developers can still maintain control over maximum and minimum sizes and can update other widget options whenever needed.
You can also supply separate landscape and portrait layouts for your widgets, which the system inflates as appropriate when the screen orientation changes.
App widgets can now be displayed in third party launchers and other host apps through a new bind Intent AppWidgetManager.
Simplified task navigation Android 4.
At run time, as Activities are launched, the system extracts the Up navigation tree from the manifest file and automatically creates the Up affordance navigation in the action bar.
Developers who declare Up navigation in the manifest no longer need to manage navigation by callback at run time, although they can also do so if needed.
Also available is a new TaskStackBuilder class that lets you quickly put together a synthetic task stack to start immediately or to use when an Activity is launched from a PendingIntent.
Creating a synthetic task stack is especially useful when users launch Activities from remote views, such as from Home screen widgets and notifications, because it lets the developer provide a managed, consistent experience on Back navigation.
Easy animations for Activity launch You can use a new helper class, ActivityOptions, to create and control the animation displayed when you launch your Activities.
Through the helper class, you can specify custom animation resources to be used when the activity is launched, or request new zoom animations that start from any rectangle you specify on screen and that optionally include a thumbnail bitmap.
Transitions to Lights Out and Full Screen Modes New system UI flags in View let you to cleanly transition from a normal application UI with action bar, navigation bar, and system bar visibleto "lights out mode" with status bar and action bar hidden and navigation bar dimmed or "full screen mode" with status bar, action bar, and navigation bar all hidden.
New types of remoteable Views Developers can now use GridLayout and ViewStub views in Home screen widgets and notifications.
GridLayout lets you structure the content of your remote views and manage child views alignments with a shallower UI hierarchy.
ViewStub is an invisible, zero-sized View that can be used to lazily inflate layout resources at runtime.
Live wallpaper preview Android 4.
From the preview, users can directly load the Live Wallpaper.
Higher-resolution contact photos With Android 4.
Apps can store and retrieve contact photos at that size or use any other size needed.
The maximum photo size supported on specific devices may vary, so apps should query the built-in contacts provider at run time to obtain the max size for the current device.
New Input Types and Capabilities Find out about devices being added and removed Apps can register to be notified when any new input devices are attached, by USB, Bluetooth, or any other connection type.
They can use this information to change state or capabilities as needed.
For example, a game could receive notification that a new keyboard or joystick is attached, indicating the presence of a new player.
Query the capabilities of input devices Android 4.
Apps can query the device manager to enumerate all of the input devices currently attached and learn about the capabilities of each.
Control vibrator on input devices Among other capabilities, apps can now make use of any vibrator service associated with an attached input device, such as for Rumble Pak controllers.
Animation and Graphics Vsync for apps Extending vsync across the Android framework leads to a more consistent framerate and a smooth, steady UI.
So that apps also benefit, Android 4.
This lets them optimize code android jelly bean on the UI thread and provides a stable timebase for synchronization.
The animation framework now uses vsync timing to automatically handle synchronization across animators.
For specialized uses, apps can access vsync timing through APIs exposed by a new Choreographer class.
Apps can request invalidation on the next vsync frame — a good way to schedule animation when the app is not using the animation framework.
For more advanced uses, apps can post a callback that the Choreographer class will run on the next frame.
New animation actions and transition types The animation framework now lets you define start and end actions to take when running ViewPropertyAnimator animations, to help synchronize them with other animations or actions in the application.
The action can run any runnable object.
For example, the runnable might specify another animation to start when the previous one finishes.
You can also now specify that a ViewPropertyAnimator use a layer during the course of its animation.
Previously, it was a best practice to animate complicated views by setting up a layer prior to starting an animation and then handling an onAnimationEnd event to remove the layer when the animation finishes.
Now, the withLayer method on ViewPropertyAnimator simplifies this process with a single method call.
A new transition type in LayoutTransition enables you to automate animations in response to all layout changes in a ViewGroup.
New Types of Connectivity Android Beam Android Beam is a popular NFC-based technology that lets users instantly share, just by touching two NFC-enabled phones together.
When the user triggers a transfer, Android Beam hands over from NFC to Bluetooth, making it really easy to manage the transfer of a file from one device to another.
Wi-Fi Network Service Discovery Android 4.
Developers can take advantage of Wi-Fi network service discovery to build cross-platform or multiplayer games and application experiences.
Using the service discovery API, apps can create and register any kind of service, for any other NSD-enabled device to discover.
The service is advertised by multicast across the network using a human-readable string identifier, which lets user more easily identify the type of service.
Consumer devices can use the API to scan and discover services available from devices connected to the local Wi-Fi network.
After discovery, apps can use the API to resolve the service to an IP address and port through which it can establish a socket connection.
You can take advantage of this API to build party poker android bonus deposit code features into your apps.
For example, you could let users connect to a webcam, a printer, or an app on another mobile device that supports Wi-Fi peer-to-peer connections.
Wi-Fi P2P Service Discovery introduced support for Wi-Fi Peer-to-Peer P2Pa technology that lets apps discover and pair directly, over a high-bandwidth peer-to-peer connection in compliance with the Wi-Fi Alliance's certification program.
Wi-Fi P2P is an ideal way to share media, photos, files and other types of data and sessions, even where there is no cell network or Wi-Fi available.
Pre-associated service discovery lets your apps get more useful information from nearby devices about the services they support, before they attempt to connect.
Apps can initiate discovery for a specific service and filter the list of discovered devices to those that actually support the target service or application.
On the other hand, your app can advertise the service it provides to other devices, which can discover it and then negotiate a connection.
This greatly simplifies discovery and pairing for users and lets apps take advantage of Wi-Fi P2P more effectively.
With Wi-Fi P2P service discovery, you can create apps and multiplayer games that can share photos, videos, gameplay, scores, or almost anything else — all without requiring any Internet or mobile network.
Your users can connect using only a direct p2p connection, which avoids using mobile bandwidth.
Network Bandwidth Management Android 4.
Apps can query whether the current network is metered before beginning a large download that might otherwise be relatively expensive to the user.
Through the API, you can now get a clear picture of which networks are sensitive to data usage and manage your network activity accordingly.
New Media Capabilities Media codec access Android 4.
Apps can query the system to discover what low-level media codecs are available on the device and then and use them in the ways they need.
For example, you can now create multiple instances of a media codec, queue input buffers, and receive output buffers in return.
In addition, the media codec framework supports protected content.
Apps can query for an available codec that is able to play protected content with a DRM solution available on the device.
USB Audio USB audio output support allows hardware vendors to build hardware such as audio docks that interface with Android devices.
This functionality is also exposed with the Android Open Accessory Development Kit ADK to give all developers the chance to create their own hardware.
Audio record triggering Android now lets you trigger audio recording based on the completion of an audio playback track.
This is useful for situations such as playing back a tone to cue your users to begin speaking to record their voices.
Multichannel audio Android 4.
Multichannel audio lets you deliver rich media experiences to users for applications such as games, music apps, and video players.
For devices that do not have the supported hardware, Android automatically downmixes the audio to the number of channels that are supported by the device usually stereo.
Audio preprocessing Developers can apply preprocessing effects to audio being recorded, such as to apply noise suppression for improving speech recording quality, echo cancellation for acoustic echo, and auto gain control for audio with inconsistent volume levels.
Apps that require high quality and clean audio recording will benefit from these preprocessors.
Audio chaining MediaPlayer supports chaining audio streams together to play audio files without pauses.
This is useful for apps that require seamless transitions between audio files such as music players to play albums with continuous tracks or games.
Media Router The new APIs MediaRouter, MediaRouteActionProvider, and MediaRouteButton provide standard mechanisms and UI for choosing where to play media.
Support is built-in for wired headsets and a2dp bluetooth headsets and speakers, and you can add your own routing options within your own app.
Renderscript Computation Android 4.
You can now sample textures in your Renderscript compute scripts, and new pragmas are available to define the floating point precision required by your scripts.
You can now debug your Renderscript compute scripts on x86-based emulator and hardware devices.
You can also define apologise, android game promo code really root-style kernels in a single Renderscript source file.
Android Browser and WebView In Android 4.
Google APIs and services To extend the capabilities of Android even further, several new services for Android are available.
Google Cloud Messaging for Android Google Cloud Messaging GCM is a service that lets developers send short message data to their users on Android devices, without needing a proprietary sync solution.
GCM handles all the details of queuing messages and delivering them efficiently to the targeted Android devices.
It supports message multicasting and can reach up to 1000 connected devices simultaneously with a single request.
It also supports message payloads, which means that in addition to sending tickle messages to an app on the device, developers can send up to 4K of data.
Google Cloud Messaging is completely free for all developers and sign-up is easy.
See the page for registration, downloads, and documentation.
App Encryption Starting with Android 4.
Smart App Updates Smart app updates is a new feature of Google Play that introduces a better way of delivering app updates to devices.
When developers publish an update, Google Play now delivers only the bits that have changed to devices, rather than the entire APK.
Google Play services Google Play services helps developers to integrate Google services, such as authentication, into their apps delivered through Google Play.
Google Play services is automatically provisioned to end user devices by Google Play, so all you need is a thin client library in your apps.
Because your app only contains the small client library, you can take advantage of these services without a big increase in download size and storage footprint.
Also, Google Play will deliver regular updates to the services, without developers needing to publish app updates to take advantage of them.
For more information about the APIs included in Google Play Services, see the developer page.
