Solution

  • The CameraManager class has two constants defined MIN_FRAME_WIDTH and MIN_FRAME_HEIGHT. You should modify them as desired and everything should work:

    private static final int MIN_FRAME_WIDTH = 240;  // (your desired value here)
private static final int MIN_FRAME_HEIGHT = 240; // (your desired value here)
