1263 <p>To ensure a consistent framerate, Android 4.1 extends <strong>vsync timing</strong> across all drawing and animation done by the Android framework. Everything runs in lockstep against a 16 millisecond vsync heartbeat — application rendering, touch events, screen composition, and display refresh — so frames don?t get ahead or behind.</p>
1265 <p>Android 4.1 also adds <strong>triple buffering</strong> in the graphics pipeline, for more consistent rendering that makes everything feel smoother, from scrolling to paging and animations.</p>
1267 <p>Android 4.1 reduces touch latency not only by <strong>synchronizing touch</strong> to vsync timing, but also by actually <strong>anticipating</strong> where your finger will be at the time of the screen refresh. This results in a more reactive and uniform touch response. In addition, after periods of inactivity, Android applies a <strong>CPU input boost</strong> at the next touch event, to make sure there?s no latency.</p>
1269 <p><strong>Tooling</strong> can help you get the absolute best performance out of your apps. Android 4.1 is designed to work with a new tool called <strong>systrace</strong>, which collects data directly from the Linux kernel to produce an overall picture of system activities. 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 <a href="{@docRoot}tools/index.html">Android SDK</a> (Tools R20 or higher)</p>
1279 <p>New APIs for accessibility services let you handle gestures and manage <strong>accessibility focus</strong> 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.</p>
1281 <p>Accessibility services can link their own <strong>tutorials</strong> into the Accessibility settings, to help users configure and use their services.</p>
1283 <p>Apps that use standard View components <strong>inherit support</strong> 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. </p>
1300 strong>bi-directional text</strong> in TextView and EditText elements. 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.</p>
1314 <p>The platform now supports <strong>user-installable keyboard maps</strong>, such as for additional international keyboards and special layout types. By default, Android 4.1 includes 27 international keymaps for keyboards, including Dvorak. 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).</p>
1316 <p>You can create an app to <strong>publish additional keymaps</strong> to the system. The APK would include the keyboard layout resources in it, based on standard Android keymap format. The application can offer additional keyboard layouts to the user by declaring a suitable broadcast receiver for ACTION_QUERY_KEYBOARD_LAYOUTS in its manifest. </p>
1336 <p>Android 4.1 brings a major update to the Android notifications framework. Apps can now display <strong>larger, richer notifications</strong> to users that can be expanded and collapsed with a pinch or swipe. Notifications support <strong>new types of content</strong>, including photos, have configurable priority, and can even include multiple actions.</p>
1338 <p>Through an improved <strong>notification builder</strong>, apps can create notifications that use a larger area, up to 256 dp in height. Three <strong>templated notification styles</strong> are available:</p>
1346 <p>In addition to the templated styles, you can create your own notification styles <strong>using any remote View</strong>.</p>
1348 <p>Apps can add up to three <strong>actions</strong> 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. such as by email or by phone call, without visiting the app.</p>
1365 <p>Android 4.1 introduces improved App Widgets that can <strong>automatically resize</strong>, based on where the user drops them on the home screen, the size to which the user expands them, and the amount of room available on the home screen. New App Widget APIs let you take advantage of this to <strong>optimize your app widget content</strong> as the size of widgets changes.</p>
1379 <p>You can <strong>define the intended Up navigation</strong> for individual Activity components of your UI by adding a new <strong>XML attribute</strong> in the app?s manifest file. 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.</p>
1381 <p>Also available is a new <strong>TaskStackBuilder</strong> 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.</p>
1385 <p>You can use a new helper class, <strong>ActivityOptions</strong>, 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.</p>
1393 <p>Developers can now use <strong>GridLayout</strong> and <strong>ViewStub</strong> 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.</p>
1397 <p>Android 4.1 makes it easier for users to <strong>find and install Live Wallpapers</strong> from apps that include them. If your app includes Live Wallpapers, you can now start an Activity (ACTION_CHANGE_LIVE_WALLPAPER) that shows the user a preview of the Live Wallpaper from your own app. From the preview, users can directly load the Live Wallpaper.</p>
1401 <p>With Android 4.1, you can store <strong>contact photos</strong> that are as large as <strong>720 x 720</strong>, making contacts even richer and more personal. 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 <strong>query the built-in contacts provider</strong> at run time to obtain the max size for the current device. </p>
1408 <p>Apps can <strong>register to be notified</strong> 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.</p>
1418 <p>Among other capabilities, apps can now make use of any <strong>vibrator service</strong> associated with an attached input device, such as for <strong>Rumble Pak</strong> controllers.</p>
1425 <p>Extending vsync across the Android framework leads to a more consistent framerate and a smooth, steady UI. So that apps also benefit, Android 4.1 <strong>extends vsync timing</strong> to all drawing and animations initiated by apps. This lets them optimize operations on the UI thread and provides a stable timebase for synchronization.</p>
1427 <p>Apps can take advantage of vsync timing for free, through Android?s <strong>animation framework</strong>. The animation framework now uses vsync timing to automatically handle synchronization across animators.</p>
1446 <p>In Android 4.1, Android Beam makes it easier to share images, videos, or other payloads by <strong>leveraging Bluetooth for the data transfer</strong>. 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.</p>
1450 <p>Android 4.1 introduces support for multicast <strong>DNS-based service discovery</strong>, which lets applications find and connect to services offered by peer devices over Wi-Fi networks — including mobile devices, printers, cameras, media players, and others. Developers can take advantage of Wi-Fi network service discovery to build cross-platform or multiplayer games and application experiences.</p>
1461 support for Wi-Fi Peer-to-Peer (P2P), a technology that lets apps <strong>discover and pair
1462 directly</strong>, over a high-bandwidth peer-to-peer connection (in compliance with the Wi-Fi
1469 <p>Android 4.1 takes Wi-Fi P2P further, adding API support for <strong>pre-associated service discovery</strong>. 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.</p>
1473 <p>With Wi-Fi P2P service discovery, you can create apps and <strong>multiplayer games</strong> 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.</p>
1477 <p>Android 4.1 helps apps <strong>manage data usage</strong> appropriately when the device is <strong>connected to a metered network</strong>, including tethering to a mobile hotspot. 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.</p>
1484 <p>Android 4.1 provides low-level access to platform hardware and software codecs. Apps can query the system to discover what <strong>low-level media codecs</strong
1488 <p>USB audio output support allows hardware vendors to build hardware such as <strong>audio docks</strong> that interface with Android devices. This functionality is also exposed with the Android <strong>Open Accessory Development Kit</strong> (ADK) to give all developers the chance to create their own hardware.</p>
1492 <p>Android now lets you <strong>trigger audio recording</strong> 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. This feature helps you sync up recording so you don?t record audio that is currently being played back and prevents recordings from beginning too late.</p>
1496 <p>Android 4.1 supports <strong>multichannel audio</strong> on devices that have hardware multichannel audio out through the <strong>HDMI port</strong>. 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).</p>
1502 <p>Developers can apply <strong>preprocessing effects</strong> 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.</p>
1506 <p>MediaPlayer supports <strong>chaining audio streams together</strong> 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.</p>
1510 <p>The new APIs MediaRouter, MediaRouteActionProvider, and MediaRouteButton provide standard mechanisms and UI for <strong>choosing where to play media</strong>. 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.</p>
1514 <p>Android 4.1 extends Renderscript computation to give you more flexibility. You can now <strong>sample textures</strong> in your Renderscript compute scripts, and <strong>new pragmas</strong> are available to define the floating point precision required by your scripts. This lets you enable <strong>NEON instructions</strong> such as fast vector math operations on the CPU path, that wouldn?t otherwise be possible with the full IEEE 754-2008 standard.</p>
1516 <p>You can now <strong>debug</strong> your Renderscript compute scripts on <strong>x86-based emulator and hardware devices</strong>. You can also define multiple root-style kernels in a single Renderscript source file.</p>
1538 <p>Google Cloud Messaging (GCM) is a service that lets developers send <strong>short message data</strong> to their users on Android devices, without needing a proprietary sync solution. </p>
1540 <p>GCM handles all the details of <strong>queuing messages and delivering them</strong> efficiently to the targeted Android devices. It supports message <strong>multicasting</strong> and can reach up to 1000 connected devices simultaneously with a single request. It also supports message <strong>payloads</strong>, which means that in addition to sending tickle messages to an app on the device, developers can send up to 4K of data. </p>
1542 <p>Google Cloud Messaging is completely <strong>free for all developers</strong> and sign-up is easy. See the <a href="{@docRoot}google/gcm/index.html">Google Cloud Messaging</a> page for registration, downloads, and documentation.</p>
1550 <p>Smart app updates is a new feature of Google Play that introduces a better way of delivering <strong>app updates</strong> to devices. When developers publish an update, Google Play now delivers only the <strong>bits that have changed</strong> to devices, rather than the entire APK. This makes the updates much lighter-weight in most cases, so they are faster to download, save the device?s battery, and conserve bandwidth usage on users? mobile data plan. On average, a smart app update is about <strong>1/3 the size</strong> of a full APK update.</p>
1554 <p>Google Play services helps developers to <strong>integrate Google services</strong> such as authentication and Google+ into their apps delivered through Google Play.</p>
1556 <p>Google Play services is automatically provisioned to end user devices by Google Play, so all you need is a <strong>thin client library</strong> in your apps.</p>
1558 <p>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 <strong>deliver regular updates</strong> to the services, without developers needing to publish app updates to take advantage of them.</p>
