I leave the camera detail view on and the phone locks, wait about 5-6
seconds, and go to unlock the phone. The camera view would be vertical
then
horizontal, and suddenly become black then the view restore to the
status
when I leave. in this process, the view size would adjust twice.
I trace the WindowManagerService.java at the function Configuration
updateOrientationFromAppTokensLocked(Configuration appConfig, IBinder
freezeThisOneIfNeeded) I find a strange thing. see the code
....
boolean changed = false;
long ident = Binder.clearCallingIdentity();
try {
int req = computeForcedAppOrientationLocked();
if (req != mForcedAppOrientation) {
changed = true;
mForcedAppOrientation = req;
//send a message to Policy indicating orientation
change to
take
//action like disabling/enabling sensors etc.,
mPolicy.setCurrentOrientationLw(req);
}
....
the mForcedAppOrientation would change to 5, this cause the force
orientation. anyone could give some advice?
thanks in advance!
