【问题描述】：

当我尝试在使用 proguard 的同时构建我的项目时，我在预验证时收到以下错误。

Preverifying...

我在 proguard 中添加了以下内容，其他库也有其他规则。

-keep class com.google.android.gms.**  *; 
-dontwarn com.google.android.gms.**
-keep class com.facebook.ads.**  *; 
-dontwarn com.google.android.gms.ads.**

我的 gradle.build 有以下库

根据 Google Play 服务设置站点，无需向 proguard 添加任何内容，当我从 proguard 中删除 gms 规则时，会得到一长串类似这样的警告

Warning: com.google.android.gms.internal.zzapt$zza: can't find referenced class com.google.android.gms.common.internal.zzf$zzb

警告列表继续。如果需要，我可以添加其余的 proguard 规则。 根据 Firebase 网站，我使用的 Google Play 服务是 4.1.0，我的 Firebase 库是最新的。使用版本 15.0.1（最新）的 Google Play Google Play 位置和位置

Proguard Output

【问题讨论】：

在没有这些dontwarn 规则的情况下运行时能否添加ProGuard 的output？

@MartinZeitler 我收到了问题中提到的警告错误。

这些几乎没有关系，而输出确实......至少是它抱怨的部分。

@MartinZeitler 抱歉，我对 proguard 有点陌生，我如何获得输出？

它是常规构建日志的一部分 - 它通常非常明确地告诉我们要做什么（要定义哪些规则）......添加 -verbose 选项也可能有助于了解发生了什么在那里。

【参考方案1】：

除了com.google.android.gms.internal.* 的规则（意思是：Google Services）之外，您还缺少很多规则。 manual 解释了所有这些建议；虽然我仍然可以为那一类留下一个例子：

-verbose
-keep,includedescriptorclasses class com.google.android.gms.internal.**  *; 
-keep class com.google.android.gms.internal.** com.google.android.gms.internal.** initialize(android.content.Context);
# -dontnote com.google.android.gms.internal.**
# -dontwarn com.google.android.gms.internal.**

刚刚注释掉了dontnote 和dontwarn，因为在开发规则集时更容易得到通知。添加修饰符includedescriptorclasses 至少应该已经减少了几行抱怨——虽然你必须定义规则，直到没有更多的抱怨。这是一个漫长而麻烦的过程，没有任何默认配方 - 并且无法提供可靠的规则，同时无法使用trial & error的方法。
