The following features are available when an activity 76 has been launched into a new task stack. 77 78 An activity can be set as not resizable through the 79 `android:resizableActivity` property in the AndroidManifest. All 80 applications targeting Android N or above are resizable by default. 81 82 In split-screen mode, an activity can be started adjacent to the 83 launching activity by setting the 84 `Intent.FLAG_ACTIVITY_LAUNCH_TO_ADJACENT` flag in its intent. 85 86 Sometimes activities may choose to handle configuration changes 87 themselves (for example for games or OpenGL-based applications). In this 88 case, setting 89 `android:configChanges=screenSize|smallestScreenSize|screenLayout|orientation` 90 in the AndroidManifest definition of the activity enables callbacks for 91 all configuration changes that may occur during multi-window use for the 92 Activity. See [Handling Runtime Changes][1]. 93 94 In freeform mode (where applications can be freely resized), activities 95 can be started within a certain area of the screen using the 96 `ActivityOptions#setLaunchBounds` call. 97 98 Alternatively, the preferred and minimum sizes can be set in a new 99 `layout` property in the AndroidManifest. 100 101 102 [1]: https://developer.android.com/guide/topics/resources/runtime-changes.html 103 ]]> 104 </intro> 105 </metadata> 106 </sample> 107
