OrientationEventlistener won't work when the device isn't rotating/moving.

I find display listener is a better way to detect the change.

     DisplayManager.DisplayListener mDisplayListener = new DisplayManager.DisplayListener() {
        @Override
        public void onDisplayAdded(int displayId) {
           android.util.Log.i(TAG, "Display #" + displayId + " added.");
        }

        @Override
        public void onDisplayChanged(int displayId) {
           android.util.Log.i(TAG, "Display #" + displayId + " changed.");
        }

        @Override
        public void onDisplayRemoved(int displayId) {
           android.util.Log.i(TAG, "Display #" + displayId + " removed.");
        }
     };
     DisplayManager displayManager = (DisplayManager) mContext.getSystemService(Context.DISPLAY_SERVICE);
     displayManager.registerDisplayListener(mDisplayListener, UIThreadHandler);
