我不得不重复这个问题，但没有解决方案正在发挥作用。
我收到以下错误

答案 0 :(得分：2)
正如您的logcat所说：
Caused by: java.lang.SecurityException: The Maps API requires the additional following
permissions to be set in the AndroidManifest.xml to ensure a correct behavior:
06-22 18:58:27.880: E/AndroidRuntime(9149): <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
您必须在清单文件中添加以下permisiion以检查互联网状态：
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
将此添加到您的清单中，它将解决您的问题。
