在使用 Proguard 构建 apk 时，我看到了这些警告：

我正在使用 Google Play Services 10.2.0，模块 ads、ads-lite、analytics、analytics-impl、base、basement、drive、games、tasks。

需要包含哪些模块或库来修复这些警告？

【解决方案1】：

基于这个thread，如果你使用ProGuard，你需要保留一些GMS（Google Play Services）类，并用@com.google.android.gms.common.annotation.KeepName注解。

您需要像编译一样忽略，但您还需要保留该类，以便它可以在运行时找到它。

将这两行添加到您的 proguard 配置文件中：
-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**
