Disabling Multi-window feature for Android N not working for an activity

I want to disable multi-window support for an activity in my app.
I have set

resizeableActivity
to false in my Manifest but when I long press recent app icon, the app still goes in multi-window mode. Below is my manifest:

<activity
android:name=".MainActivity"
android:resizeableActivity="false"
android:excludeFromRecents="true"
android:icon="@drawable/ic_launcher_home"
android:theme="@style/AppThemeV3.CustomToolbar">
</activity>


Per documentation:


android:resizeableActivity=["true" | "false"]


If the attribute is set to false, the activity does not support multi-window mode. If this value is false, and the user attempts to launch the activity in multi-window mode, the activity takes over the full screen.


I have also tried to set this attribute to false at application level in manifest but it still starts in multi-window mode. Any pointer on what I am doing wrong will be highly appreciated?

Answer

The activity that is at the root of the task controls the window size. Your choices are:

  1. Trace back to all possible task root activities in your app and ensure they all also have android:resizeableActivity="false"

  2. Force this activity into another task, via Intent flags when you start it or manifest settings
