在应用程序实例中尝试初始化我的应用程序中的admob sdk时遇到以下问题。当我们添加
android: name =".MyApplication"AndroidManifest.xml
Exception at,MobileAds.initialize( this, new OnInitializationCompleteListener() { @Override public void onInitializationComplete( @NonNull InitializationStatus initializationStatus) {} });
注意:如果我在活动级别初始化相同，没有发现问题。
'W/System.err: com.google.android.gms.common.GooglePlayServicesMissingManifestValueException: A required meta-data tag in your app's AndroidManifest.xml does not exist. You must have the following declaration within the <application> element: <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />'
E/MetadataValueReader: This should never happen.

显示错误，因为您没有添加它。AdmobQuickStart这个链接你可以得到详细的安装信息

请注意，永远不要在Application对象中存储可变的共享数据，因为这些数据随时可能消失或失效。相反，使用持久化策略(如file、SharedPreferences或SQLite)存储任何可变的共享数据。

不应该在Application类中创建单例实例。
