        ActivityContext = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity");
	//Ensure to invoke "init" function first before using all interfaces.
        ajo.Call("init", ActivityContext);
    }
    public void androidShutDown()
    {
        Debug.Log("androidShutDown");
        ajo.Call("androidShutDown");
