我正在使用谷歌播放服务和谷歌地图。
当我尝试在设备上调试应用程序（三星S3）时出现此错误，在模拟器上工作正常：

The API key for Google Maps-based APIs is defined as a string resource.
(See the file "res/values/google_maps_api.xml").
Note that the API key is linked to the encryption key used to sign the APK.
You need a different API key for each encryption key, including the release key that is used to
sign the APK for publishing.
You can define the keys for the debug and release targets in src/debug/ and src/release/.
