Android Google Maps v2自动化失败

出现此错误。很抱歉问这个问题，但我不能调查

12-29 12:03:59.705: E/Google Maps Android API(15395): Authorization failure.  Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.
12-29 12:03:59.720: E/Google Maps Android API(15395): In the Google Developer Console (https://console.developers.google.com)
Google Maps Android API: Ensure that the following correspond to what is in the API Console: Package Name: com.example.testmaps, API Key: XXX, Certificate Fingerprint: ZZZ
Google Maps Android API: Failed to contact Google servers. Another attempt will be made when connectivity is established.
Google Maps Android API: Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors). 

这是清单文件的代码：

检查三星S4

解决方案： 似乎它是需要使用的 导入com.google.android.gms 而不是 导入com.google.android.m4b

对于地图

您在Eclipse/Android Studio中开发代码。如果您使用Eclipse尝试导入库项目，位于：Android-SDK-DIRECTORY/extras/google/google\u play\u services/libprojects，请确保使用您的发布密钥对应用程序进行签名，并将发布密钥放在开发者控制台中，如果您尝试在emulator或手机上运行而未导出和签署应用程序，则您正在使用调试密钥。是否已将库项目导入工作区。您正在开发的项目和库项目应位于同一工作目录中。是。我在我的项目中导入了google_play_服务。具体目标21。
