        AndroidJavaObject obj =
            clazz.CallStatic<AndroidJavaObject>("getInstance");

        var androidJC = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        var activity = androidJC.GetStatic<AndroidJavaObject>("currentActivity");

        int value = obj.Call<int>("isGooglePlayServicesAvailable", activity);

        // 0 == success
