java Android Admob未在emulator中显示它为空

Question

我一直在遵循安卓快速入门教程https://developers.google.com/mobile-ads-sdk/docs/admob/安卓/quick-start将Admob放在模拟器上，但它不起作用，可能缺少什么。我基本上是逐字复制了教程，但它不起作用。我还检查了我的日志，发现这个错误找不到类的安卓。应用程序。AppOpsManager’，引用自方法com。谷歌。安卓gms。常见的谷歌PlayServiceSutil。zza。这似乎是他们的内部错误。我也刚刚升级到新的Android Studio 1.2.1.1。这是我的基本代码

Main。java

  protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        AdView mAdView = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        mAdView.loadAd(adRequest);
    }

将以下内容添加到代码中：

AdRequest adRequest = new AdRequest.Builder()
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)    // remove when exporting signed APK
        .addTestDevice(getDeviceId())       // remove when exporting signed APK
        .build();
