Question

我正在使用Google Map Api创建一些应用。我加载了google_play_service，获得了API_KEY，将其插入Manifest.xml，但它确实无效。我做错了什么？这是日志

     Check that <meta- data android:name="com.google.android.maps.v2.API_KEY" 
     android:value="your API key"/> is in  the <application> element of AndroidManifest.xml

Answer 1

在清单文件中的应用程序下添加以下元数据：

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" />

<meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

Answer 2

您是否在项目中添加了google_play_service.jar库？有时您需要导入google_play_service项目并将其标记为＆＃34;是库＆＃34;。你还得到同样的错误吗？
