java - Proguard 错误：“找不到...的通用超类”

问题描述

在 Android Studio 中构建我的应用程序时出现此错误：

Unexpected error while performing partial evaluation:

  Method      = [zza(Lcom/google/android/gms/internal/zzmk;Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Lcom/google/android/gms/internal/zznh;Lcom/google/android/gms/internal/zzgl;Lcom/google/android/gms/internal/zznb;)Lcom/google/android/gms/internal/zzmn;]

我该如何解决？

标签： javaandroidgoogle-play-servicesproguard

解决方案

你有不同版本的 Play Service 库吗？确保对所有库使用相同的版本：

implementation 'com.google.android.gms:play-services-analytics:16.0.1'
implementation 'com.google.android.gms:play-services-auth:11.8.0' // should be the same version

某些版本具有不同的实现和 API，这会导致内部冲突，也会影响 Proguard。
