| Immersive | 2048 | Bit in flags corresponding to an immersive activity that wishes not to be interrupted by notifications. Applications that hide the system notification bar with WindowManager.LayoutParams.FLAG_FULLSCREEN may still be interrupted by high-priority notifications; for example, an incoming phone call may use fullScreenIntent to present a full-screen in-call activity to the user, pausing the current activity as a side-effect. An activity with FLAG_IMMERSIVE set, however, will not be interrupted; the notification may be shown in some other way (such as a small floating "toast" window). Note that this flag will always reflect the Activity's android:immersive manifest definition, even if the Activity's immersive state is changed at runtime via Activity.setImmersive(boolean).
