Android: Call Activity.setVrModeEnabled
We would do this in the application (client) process after connecting. We'd mention our own package/class as the component. Not supported on all devices, so would have to check (for hasSystemFeature("android.software.vr.mode")
) and still probably wrap in try, in case something weird happens (user disables us in the vr listener settings but not elsewhere, etc).
I think this should be enough to get low-persistence mode on displays that have it.
