Introduction Combining Speed with Smoothness 4. Page contents. 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. 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.
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 should never appear in screenshots or on a non-secure display output, even when mirrored. 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.
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 provides 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.
For more control over your UI components and to make them more modular, 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 now 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. 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. 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.
These changes allow the operating system to run at a full 60 frames per second on capable hardware. Following 4. Alongside Android 4.
This allows the addition of certain forms of functionality without having to distribute an upgrade to the operating system itself, addressing the infamous "fragmentation" problems experienced by the Android ecosystem.
