我设置了google api并在具有google play服务的三星设备上运行该应用程序，但是即使我有互联网连接并激活了google位置，我也没有在屏幕上显示带有google徽标的屏幕。 >

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/.
