Immersive mode instructions reappear every time the device enters this mode
问题 My app uses the new "immersive mode" by calling (in onCreate ): getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY); This works great, but the "how-to" popup ("Swipe down from the top to exit full screen") appears every time the Activity is launched (if the phone is being locked while the activity was showing), even though the user has acknowledged the popup. As far as I understand, the popup is automatically generated
