答案 0 :(得分：0)
将Google Play服务版本添加到您应用的清单中。请参阅本指南here
编辑应用程序的AndroidManifest.xml文件，并在元素中添加以下声明。这会嵌入应用程序编译的Google Play服务版本。
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
同样在异常中你可以看到上面提到的修复。
答案 1 :(得分：0)
您必须在元素中包含以下声明：
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
