库版本11.2.0的firebase ProGuard错误(警告)

Question

我正在研究11.0.4 firebase库版本.今天我已切换到最新版本:11.2.0,当我尝试构建发布版本(启用ProGuard)时,我收到错误消息:

Warning:com.google.android.gms.internal.zzbdo: can't find referenced method 'boolean isInstantApp(java.lang.String)' in library class android.content.pm.PackageManager
Warning:there were 1 unresolved references to library class members.
Warning:Exception while processing task java.io.IOException: Please correct the above warnings first.
Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> Job failed, see logs for details

和gradle控制台:

Warning: there were 1 unresolved references to library class members.
         You probably need to update the library versions.

Answer 1

我使用的是API 25(rev.3),该方法isInstantApp已在API 26中添加.更改targetSdkVersion为此版本重新解决了问题.

Answer 2

对于那些不想开始使用运行时权限的人,你不需要增加targetSdkVersion,增加compileSdkVersion就足够了.
