Google移动广告（AdMob）-不显示广告

Question

我的代码看起来与原始代码一模一样(https://developers.google.com/mobile-ads-sdk/docs/admob/fundamentals?hl=en#play)我确信我正确导入了所有内容，向我的AndroidManifest添加了元数据、活动和权限。

当我在我的设备上启动应用程序时，logcat 会给我以下内容：

03-23 10:18:45.874: E/GooglePlayServicesUtil(12473): The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.
03-23 10:18:45.974: D/WebView(12473): onSizeChanged - w:960 h:150
03-23 10:18:46.094: W/ActivityThread(12473): ClassLoader.loadClass: The class loader returned by Thread.getContextClassLoader() may fail for processes that host multiple applications. You should explicitly specify a context class loader. For example: Thread.setContextClassLoader(getClass().getClassLoader());
03-23 10:19:17.244: E/GooglePlayServicesUtil(12473): The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.
03-23 10:19:17.265: E/GooglePlayServicesUtil(12473): The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.
03-23 10:20:17.243: W/Ads(12473): Timed out waiting for ad response.
03-23 10:20:17.253: E/SQLiteLog(12473): (14) cannot open file at line 32512 of [00bb9c9ce4]
03-23 10:20:17.253: I/Ads(12473): Scheduling ad refresh 60000 milliseconds from now.
03-23 10:20:17.263: W/Ads(12473): Failed to load ad: 2

找不到此Google Play服务资源和加载广告失败错误每分钟重复一次。

我的UnitId是正确的，我的TestDevice Id也是正确的。

Answer 1

我认为带有“加载失败（无效请求）”的toast消息可能是因为您没有用真实的广告单元ID更新字符串INSERT_YOUR_AD_UNIT_ID_HERE，您必须通过向AdMob或其他广告提供商注册帐户并请求应用程序的ID来获得该ID。
