Android includes APIs and facilities to build “Virtual Reality” (VR) applications including high quality mobile VR experiences. Device implementations MUST properly implement these APIs and behaviors, as detailed in this section.
Android includes support for [VR Mode]( https://developer.android.com/reference/android/app/Activity.html#setVrModeEnabled%28boolean, android.content.ComponentName%29), a feature which handles stereoscopic rendering of notifications and disables monocular system UI components while a VR application has user focus.
If device implementations identify the support of high performance VR for longer user periods through the android.hardware.vr.high_performance
feature flag, they:
