将Admob添加到libgdx

Question

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);

什么也没显示，没有广告，为什么，我也在build.gradle（Project：projectN）中添加了编译“
com.google.android.gms：play-services-ads：$ admobVersion”

使用Ubuntu 16.04，Android Studio

添加不带Firebase的AdMob广告：

1. 将这些行放入build.gradleandroid模块中。

        dependencies {

        compile 'com.google.android.gms:play-services-ads:10.2.4'
    }

1. 在AndoidManifest.xml文件中添加权限

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

如果要使用非页内广告，则<application添加内部代码Activity

        <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" />

1. AndroidLauncher类。

        public class AndroidLauncher extends AndroidApplication {

    private static final String adUnitId="ca-app-pub-xxxxxxxxxxxxxxxxxxxxx";
    private AdView adView;

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

        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();
        adRequestBuilder.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);
        adView.loadAd(adRequestBuilder.build());

        RelativeLayout.LayoutParams topParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
        topParams.addRule(RelativeLayout.ALIGN_PARENT_TOP,RelativeLayout.TRUE);
        topParams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
        layout.addView(adView, topParams);
        adView.setBackgroundColor(android.graphics.Color.TRANSPARENT);

        setContentView(layout);
    }

    @Override
    protected void onResume() {
        super.onResume();
        adView.resume();
    }

    @Override
    protected void onPause() {
        super.onPause();
        adView.pause();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        adView.destroy();
    }
    }
