Answer 1

The default screenOrientation mode behavior is vendor and device specific. For phones, it's typical that only -90°, 0° and 90° are supported.

To support all orientations, add android:screenOrientation="fullSensor" to your activity's manifest entry.

Answer 2

Kind of late answer but it may help in the future.

Call setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR) in your main activity's onCreate method.

Below works for me.

MainActivity.this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR);
