android - 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。今天我已经切换到最新版本:11.2.0，当我尝试构建发布版本(启用 ProGuard)时，我收到错误:

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)，方法 isInstantApp 是在 API 26 中添加的。将 targetSdkVersion 更改为此版本解决了问题。
