Android Admob 没有在模拟器中显示它是空白的

Question

我一直在关注 android 快速入门教程 https://developers.google.com/mobile-ads-sdk/docs/admob/android/quick-start 将 Admob 放在模拟器上，但它无法工作可能缺少的内容。我基本上逐字复制了教程，但它不起作用。我也检查过我的 Logcat 并收到此错误 Could not find class 'android.app.AppOpsManager', referenced from method com.google.android.gms.common.GooglePlayServicesUtil.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 值得。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);
    }

将此添加到您的代码中：

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