Question

当我尝试使用Proguard构建项目时，在进行预验证时出现以下错误。

Preverifying...
Unexpected error while performing partial evaluation:
  Class       = [com/google/android/gms/internal/zzmz]
  Method      = [zza(Lcom/google/android/gms/internal/zzmh;Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Lcom/google/android/gms/internal/zzne;Lcom/google/android/gms/internal/zzgf;Lcom/google/android/gms/internal/zzmy;)Lcom/google/android/gms/internal/zzmk;]

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

    debugImplementation 'com.amitshekhar.android:debug-db:1.0.4'

根据Google Play服务设置网站，当我从proguard删除gms规则时，无需添加任何内容来保护proguard，

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

Warning: com.google.android.gms.internal.zzapt$zza: can't find referenced method 'boolean isConnecting()' in program class com.google.android.gms.internal.zzapu

警告列表继续。如果需要，我可以添加其他proguard规则。据Firebase网站称，我正在使用的Google Play服务是4.1.0，并且我的Firebase库是最新的。使用适用于Google Play的位置和位置的15.0.1版（最新）

除了com.google.android.gms.internal.*（即：Google Services）之外，您还缺少很多规则。 manual解释了所有这些建议；尽管我仍然可以举一个例子，但对于那个班级：

-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.**

仅注释掉dontnote和dontwarn，因为在开发规则集时更容易收到所有通知。添加修饰符includedescriptorclasses应该至少已经减少了几行抱怨-在您必须定义规则的同时，直到不再有抱怨为止。这是一个漫长而麻烦的过程，没有任何默认配方-并且在无法使用trial & error方法的情况下，提供可靠的规则是非常不可能的。

使用proguard
