将 Admob 添加到 libgdx

    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);

没有显示任何内容，没有广告，为什么， 我还在 build.gradle 中添加了（项目：projectN） 编译“com.google.android.gms:play-services-ads:$admobVersion”

使用ubuntu 16.04，android-studio

在不使用 Firebase 的情况下添加 AdMob 广告：

1. 把这些线放进去build.gradleandroid 模块。

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

2. 添加权限于AndoidManifest.xml file

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

   Inside <application标签添加Activity如果想使用插页式广告

   <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" />
   

3. 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();
   }
   }
