add this code in onCreate in main Activity :

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE);
  }

You can just add this attribute to your activity in the AndroidManifest:

android:screenOrientation="landscape"
