It shows the use of new Intent flags and +AndroidManifest properties to define the multi-window behavior. +Switch the sample app into multi-window mode to see how it affects +the lifecycle and behavior of the app. + +Introduction +------------ + +Android N introduces new APIs to support multiple activities +to be displayed at the same time. + +Activities that are started within the same task stack +inherit their multiwindow properties from the activity that fired +off the intent. The following features are available when an activity +has been launched into a new task stack. + +An activity can be set as not resizable through the +`android:resizableActivity` property in the AndroidManifest. All +applications targeting Android N or above are resizable by default. + +In split-screen mode, an activity can be started adjacent to the +launching activity by setting the +`Intent.FLAG_ACTIVITY_LAUNCH_TO_ADJACENT` flag in its intent. + +Sometimes activities may choose to handle configuration changes +themselves (for example for games or OpenGL-based applications). In this +case, setting +`android:configChanges=screenSize|smallestScreenSize|screenLayout|orientation` +in the AndroidManifest definition of the activity enables callbacks for +all configuration changes that may occur during multi-window use for the +Activity. See [Handling Runtime Changes][1]. + +In freeform mode (where applications can be freely resized), activities +can be started within a certain area of the screen using the +`ActivityOptions#setLaunchBounds` call. + +Alternatively, the preferred and minimum sizes can be set in a new +`layout` property in the AndroidManifest. + + +[1]: https://developer.android.com/guide/topics/resources/runtime-changes.html + +Pre-requisites +-------------- + +- Android SDK 27 +- Android Support Repository + +Screenshots +------------- + +<img src="screenshots/main.png" height="400" alt="Screenshot"/> + +Getting Started +--------------- + +This sample uses the Gradle build system.
