What is the Camera2 API Equivalent of setDisplayOrientation()?

Question

With android.hardware.Camera, in order to have the camera output appropriately track the device movement, we need to hook up an OrientationEventListener

Answer 1

use the formula below to get device rotation.

private int getOrientation(int rotation) {
    return (ORIENTATIONS.get(rotation) + mSensorOrientation + 270) % 360;
}

SensorOrientation is a field assigned from

characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION)
