回调Unity是空的

我在Unity中创建了一个回调,使我能够将结果从Android应用程序发送回Unity应用程序。我更喜欢UnitySendMessage,因为它更“干净”。

我使用了这里给出的确切示例:Callback Listener in Unity - How to call script file method from UnityPlayerActivity in Android

Unity c#code:

public class MoviePlayer : MonoBehaviour {

// Use this for initialization
void Awake () {

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


    StartUpCallback startupCallback = new StartUpCallback();
    AndroidJavaObject control = new AndroidJavaObject("vrbridge.Control", activity);
    //control.Call("startUp");
    control.Call("startUp", startupCallback);

}

class StartUpCallback:  AndroidJavaProxy
{
    public StartUpCallback() : base("vrbridge.StartUpCallback") { }

    public void OnSuccess() { }
    public void OnFailure() { }
}
}

Android代码:

public class Control implements LibraryManagerInitStartDialogFragment.ConfigurationFragmentListener{

String TAG = "QuickPlayTest";


private Activity _activity;
private StartUpCallback _startUpCallback;

public Control(){
    Log.d(TAG, "Constructor.");

}

public Control(Activity activity){
    Log.d(TAG, "Constructor. Activity = " + activity);
    _activity = activity;
}


public void startUp(StartUpCallback startUpCallback){
    Log.d(TAG, "startUp. Callback = " + startUpCallback);
    _startUpCallback = startUpCallback;
    new LibraryManagerInitStart(_activity, this);
    Log.d(TAG, "startUp - end");
}
}

public interface StartUpCallback {
    public void onSuccess();
    public void onFailure();
}

由于某种原因,startup()中的参数startUpCallback始终为null。

我尝试将其转换为具有相同结果的构造函数。 OTOH,活动的价值还可以。

我错过了什么吗?

问题可能是您的C#代理没有正确实现Java接口。请注意单词&#34; on / On&#34;中的大小写差异。
