72.6 Enabling Multi-Window Support in an App
The android:resizableActivity manifest file setting controls whether multi-window behavior is supported by an app. This setting can be made at either the application or individual activity levels. The following fragment, for example, configures the activity named MainActivity to support both split-screen and freeform multi-window modes:
<activity
android:name=".MainActivity"
android:resizeableActivity="true"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />...
