Android มีใครเคยใช้ youtube api ไหมครับ ผมอยากรู้วิธี savestate อะครับ

@Override
	protected void onSaveInstanceState(Bundle outState) {
		super.onSaveInstanceState(outState);
		outState.putInt("currentposition",  vdo1.getCurrentPosition ());
	}
	@Override
	protected void onRestoreInstanceState(Bundle savedInstanceState) {
		super.onRestoreInstanceState(savedInstanceState);
		vdo1.seekTo(savedInstanceState.getInt("currentposition"));
	}
