Java 将Admob添加到libgdx

什么都没有显示，没有广告，为什么， 我还在build.gradle项目中添加了：projectN 编译com.google.android.gms:play服务广告：$admobVersion

使用ubuntu 16.04，android studio在不使用Firebase的情况下添加AdMob广告：

将这些行放在android模块的build.gradle中

    RelativeLayout layout = new RelativeLayout(this);
    AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
    View gameView = initializeForView(new MainGame(), config);

    layout.addView(gameView);


    adView = new AdView(this);

    adView.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {
            System.out.println("LOAD");
        }
    });
    adView.setAdSize(AdSize.SMART_BANNER);
    adView.setAdUnitId("ca-app-xxx-xxxxxxxxxx/xxxxxxxxxx");

    AdRequest.Builder builder = new AdRequest.Builder();
    RelativeLayout.LayoutParams adParams = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.WRAP_CONTENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT
    );
    layout.addView(adView, adParams);
    adView.loadAd(builder.build());

    setContentView(layout);

在AndoidManifest.xml文件中添加权限

AndroidLauncher类

<meta-data android:name="com.google.android.gms.version"
           android:value="@integer/google_play_services_version" />

<activity android:name="com.google.android.gms.ads.AdActivity"
          android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
          android:theme="@android:style/Theme.Translucent" />

builder.AddTestDeviceAddRequest.device\u ID\u EMULATOR调试添加测试设备的可能副本；查看我的问题并在此处提供代码：没有firebase，我也没有布局，因为我是通过CodingSchool教程完成的。如果您有时间，请查看我的问题：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    RelativeLayout layout = new RelativeLayout(this);
    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
    layout.setLayoutParams(params);

    View gameView=initializeForView(new MyGdxGame(), config);

    RelativeLayout.LayoutParams gameViewParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    gameViewParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
    gameViewParams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);

    gameView.setLayoutParams(gameViewParams);
    layout.addView(gameView);

    adView = new AdView(this);
    adView.setAdSize(AdSize.BANNER);
    adView.setAdUnitId(adUnitId);

    AdRequest.Builder adRequestBuilder = new AdRequest.Builder();

    topParams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
    layout.addView(adView, topParams);
    adView.setBackgroundColor(android.graphics.Color.TRANSPARENT);

    setContentView(layout);

@Override

    adView.destroy();
