Unity调用安卓的Toast

一：Unity中C#主导

AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
            AndroidJavaClass Toast = new AndroidJavaClass("android.widget.Toast");
            currentActivity.Call("runOnUiThread", new AndroidJavaRunnable(() =>
            {
                Toast.CallStatic<AndroidJavaObject>("makeText", currentActivity, "Show Android Toast", Toast.GetStatic<int>("LENGTH_LONG")).Call("show");
            }));

            //匿名方法中第二个参数是安卓上下文对象，除了用currentActivity，还可用安卓中的GetApplicationContext()获得上下文
            //AndroidJavaObject context = currentActivity.Call<AndroidJavaObject>("getApplicationContext");

二：Android Studio中Java主导
