![]() An activity can, however, be launched into a new task stack by passing through the appropriate flags with the intent. ![]() By default, activities launched via an intent are considered to reside in the same task stack as the originating activity. In the Getting started with Explicit, Implicit and Pending Intents, an example app was created in which an activity uses an intent to launch a second activity. Launching an Activity in Multi-Window Mode Activity has entered multi-window mode Super.onMultiWindowModeChanged(isInMultiWindowMode, newConfig) The new configuration settings are contained within the Configuration object passed as the second void onMultiWindowModeChanged(boolean isInMultiWindowMode, The first argument passed to this method is true on entering multi-window mode, and false when the activity exits the mode. ![]() Activity is running in Multi-Window modeĪn activity will receive notification that it is entering or exiting multi-window mode if it overrides the onMultiWindowModeChanged() callback method. When called, this method returns a true or false value depending on whether or not the activity is currently full screen: The current status can be obtained via a call to the isInMultiWindowMode() method of the Activity class. Situations may arise where an activity needs to detect whether it is currently being displayed to the user in multi-window mode. When a device is in multi-window mode, the title bar of such activities will also display a message within the Overview screen indicating that multi-window mode is not supported by the activity.ĭetecting Multi-Window Mode in an Activity Launching an activity for which multi-window support is disabled will result in a message appearing indicating that the app does not support multi-window mode and the activity filling the entire screen. Setting the property to false will prevent the activity from appearing in split-screen or freeform mode. The following fragment, for example, configures the activity named MainActivity to support both split-screen and freeform multi-window modes: This setting can be made at either the application or individual activity levels. The android:resizableActivity manifest file setting controls whether multi-window behavior is supported by an app. If your targetSdkVersion is 24 (Nougat) or higher, this will be set to true by default (you can still turn it off by setting the param to false). ![]() At present this feature is only available on Android TV.Īdd this to your application or activity tag in AndroidManifest.xml:Īdding it to application will make all activities realizable, while adding it to a specific activity will keep other activities incompatible with resizing. ![]() Picture-in-picture support, as the name suggests, allows video playback to continue in a smaller window while the user performs other tasks. Following figure, for example, shows a device in freeform mode with the Calculator and Contacts apps displayed in separate windows: Freeform differs from split-screen mode in that it allows each activity to appear in a separate, resizable window and is not limited to two activities being displayed concurrently. To exit split-screen mode, simply drag the divider separating the two activities to a far edge so that only one activity fills the screen, or press and hold the Overview button until it reverts to a single square.įreeform mode provides a windowing environment on devices with larger screens and is currently enabled at the discretion of the device manufacturer. Alternatively, an app may be placed in split-screen mode by displaying the Overview screen, pressing and holding the title bar of a listed app and then dragging and dropping the app onto the highlighted section of the screen. The Overview screen will appear in the adjacent half of the screen allowing the second activity to be selected for display. Once in split-screen mode, the Overview button will change to display two rectangles and the current activity will fill one half of the screen. Split-screen mode can be entered by pressing and holding the square Overview button until the display switches mode. ![]()
