Android 使用LibGDX实现AdMob奖励视频

我正在用LibGDX创建一个游戏，想在上面放一些有奖励的视频，但我不知道怎么做

我已经在本教程中显示了admob横幅：

我已经看到了这个问题，但不明白该把代码放在哪里：

public void showVideoAd(){
        runOnUiThread(new Runnable() {
            public void run() {

                if (mAd.isLoaded()) {
                   mAd.show();
                } else {
                    loadRewardedVideoAd();
                }
            }
        });
}

public boolean hasVideoReward(){

    return isRewardLoaded; 
    //return mAd.isLoaded();    // -> must be called on the main UI thread.
}

（首先，其中未声明任何mAd）：

最后一次，我又做了几次实验：

AdHandler.java：

public interface AdHandler {
    public void showVideo();
}

安德鲁伊德拉舍尔：

public class AndroidLauncher extends AndroidApplication implements AdHandler {
    RewardedVideoAd rewardedVideoAd;

    @Override
    public void showVideo() {
        if (rewardedVideoAd.isLoaded()) {
            rewardedVideoAd.show();
        }
    }

        Handler handler = new Handler();
        @Override
        protected void onCreate (Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
            initialize(new Restart(this), config);

            rewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
            rewardedVideoAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {
            @Override
            public void onRewardedVideoAdLoaded() {

            }

            @Override
            public void onRewardedVideoAdOpened() {

            }

            @Override
            public void onRewardedVideoStarted() {

            }

            @Override
            public void onRewardedVideoAdClosed() {

            }

            @Override
            public void onRewarded(RewardItem rewardItem) {

            }

            @Override
            public void onRewardedVideoAdLeftApplication() {

            }

            @Override
            public void onRewardedVideoAdFailedToLoad(int i) {

            }
        });

        loadRewardedVideoAd();
    }

    private void loadRewardedVideoAd() {
        rewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917", new AdRequest.Builder().build());
    }
}

public class AndroidLauncher extends AndroidApplication implements AdHandler {
    RewardedVideoAd rewardedVideoAd;

    @Override
    public void showVideo() {
        runOnUiThread(new Runnable() {
            @Override public void run() {
                if (rewardedVideoAd.isLoaded()) {
                    rewardedVideoAd.show();
                }
            }
        });
    }

    @Override
    protected void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
        initialize(new Restart(this), config);

        MobileAds.initialize(this, "ca-app-pub-3940256099942544~3347511713");

        rewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
        rewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917", new AdRequest.Builder().build());
        rewardedVideoAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {
            @Override
            public void onRewardedVideoAdLoaded() {

            }

            @Override
            public void onRewardedVideoAdOpened() {

            }

            @Override
            public void onRewardedVideoStarted() {

            }

            @Override
            public void onRewardedVideoAdClosed() {
                rewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917", new AdRequest.Builder().build());
            }

            @Override
            public void onRewarded(RewardItem rewardItem) {

            }

            @Override
            public void onRewardedVideoAdLeftApplication() {

            }

            @Override
            public void onRewardedVideoAdFailedToLoad(int i) {

            }
        });
    }
}

然后我在android类上有以下代码：

AdHandler adHandler;

    public Restart(AdHandler handler) {
         this.adHandler = handler;
    }

最后我打电话给你

    adHandler.showVideo();

在render（）上，是什么导致了错误

java.lang.IllegalStateException:必须在主服务器上调用isLoaded 用户界面线程

（我真的不知道这是什么意思）

如果有人能给我一个完整的工作项目与LibGDX+AdMob奖励视频将是可怕的

[编辑]

所以，经过几次测试，我已经能够使它工作，我只需要改变

    @Override
    public void showVideo() {
        if (rewardedVideoAd.isLoaded()) {
            rewardedVideoAd.show();
        }
    }

到

这就解决了我之前说过的错误

现在代码是这样的：

java：未更改

Andoid发射器：

public class AndroidLauncher extends AndroidApplication implements AdHandler {
    RewardedVideoAd rewardedVideoAd;

    @Override
    public void showVideo() {
        runOnUiThread(new Runnable() {
            @Override public void run() {
                if (rewardedVideoAd.isLoaded()) {
                    rewardedVideoAd.show();
                }
            }
        });
    }

    @Override
    protected void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
        initialize(new Restart(this), config);

        MobileAds.initialize(this, "ca-app-pub-3940256099942544~3347511713");

        rewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
        rewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917", new AdRequest.Builder().build());
        rewardedVideoAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {
            @Override
            public void onRewardedVideoAdLoaded() {

            }

            @Override
            public void onRewardedVideoAdOpened() {

            }

            @Override
            public void onRewardedVideoStarted() {

            }

            @Override
            public void onRewardedVideoAdClosed() {
                rewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917", new AdRequest.Builder().build());
            }

            @Override
            public void onRewarded(RewardItem rewardItem) {

            }

            @Override
            public void onRewardedVideoAdLeftApplication() {

            }

            @Override
            public void onRewardedVideoAdFailedToLoad(int i) {

            }
        });
    }
}

Andoid类：

public class RewVideo extends ApplicationAdapter {
    AdHandler adHandler;
    public Restart(AdHandler handler) {
        this.adHandler = handler;
    }


    @Override
    public void create () {

    }

    @Override
    public void render () {
        if (Gdx.input.justTouched()) {
            adHandler.showVideo();
        }
    }

但是，它会用奇怪的消息和异常填充我的日志：

W/Ads:调用Firebase方法getInstance错误。 java.lang.ClassNotFoundException:在路径上未找到类“com.google.android.gms.measurement.AppMeasurement”：

谷歌移动广告SDK不会与Firebase集成。 Admob/Firbase集成需要最新的Firebase SDK jar，但 Firebase SDK缺失或已过期

W/Ads:服务器参数：{…}

W/DynamiteModule:未找到com.google.android.gms.ads.dynamite的本地模块描述符类

W/OkHttpClient:与的连接泄漏。你忘了关闭一个响应机构了吗

E/ACodec:[OMX.google.h264.decoder]在输出到DynamicANWBuffer时设置端口模式失败，w/err-1010

视频播放时，此消息每秒显示一次：

W/合子：尝试删除非JNI本地引用，转储线程

除了大量的信息外，我还注意到每一条都有两条信息：“广告加载完成”、“广告打开”和“广告关闭”

这正常吗
