我正在学习android谷歌地图。我已经设计了应用程序，它在kitkat中运行良好但是当我想在marshmallow中运行相同的应用程序时它会崩溃。我试图解决它，但我没有得到任何结果来解决这个问题。

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/.
