I want to disable multi-window support for an activity in my app.
I have set
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.
The activity that is at the root of the task controls the window size. Your choices are:
Trace back to all possible task root activities in your app and ensure they all also have
Force this activity into another task, via
Intent flags when you start it or manifest settings
