我尝试将位置服务作为后台服务运行。它在活动中运行良好，但是当我使用服务时，我得到了java.lang.securityException：客户端必须具有ACCESS_COARSE_LOCATION或ACCESS_FINE_LOCATION权限才能执行任何位置操作。我已经提供了适当的权限，但问题仍然存在。我正在使用nexus 5（Marshmallow）进行测试。
这是我的服务

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/.
