Answer 1

异常喜欢说：

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" /> 

添加它低于或高于谷歌地图API密钥

Answer 2

添加谷歌Play服务版本，您的应用程序的清单

编辑您的应用程序的AndroidManifest.xml文件，并添加 在元素之后声明。这嵌入了该应用程序编译的Google Play服务版本 。

您需要添加<meta-data>下<application>代码到你的AndroidManifest.xml

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

这是因为latest google play services requires a version name, which is to be mentioned using <meta-data .. /> inside AndroidManifest.xml
