minsdkerror

Answer 1

由于每10.2.0 release notes和this blog post ：

Version 10.0.0 of the Google Play services client libraries, as well as the Firebase client libraries for Android, will be the last version of these libraries that support Android API level 9 (Android 2.3, Gingerbread). The next scheduled release of these libraries, version 10.2.0, will increase the minimum supported API level from 9 to 14 (Android 4.0.1, Ice Cream Sandwich).

当您使用10.2.0，中的minSdkVersion现在是14，如果你想降低支持API 9德维奇必须使用10.0.1或更早ES。

谷歌Play业务10.2.0下降支持姜饼和只支持API 14了现在，所以如果你需要支持旧设备，那么你需要留在10.0
