Question

我正在使用ProGuard来混淆我的apk，但是类和方法名称没有变化 - 它们和以前一样。只更改变量名称。

他们中的大多数都没有扩展像Activity这样的类;我的代码中有一些继承，但它是100％由我自己编写的。

我正在使用d2j-dex2jar和jd-gui检查结果。

由于GSON的使用，某些类被排除在外，这是我的proguard-project.txt：

-keep class com.google.ads.** # Don't proguard AdMob classes
-dontwarn com.google.ads.** # Temporary workaround for v6.2.1. It gives a warning that you can ignore

# Add any classes the interact with gson
-keep class com.revicostudio.gravityrun.playerdata.PlayerData
-keep class com.revicostudio.gravityrun.playerdata.SettingsDescriptor
-keep class com.revicostudio.gravityrun.playerdata.ShipStatus
-keep class com.revicostudio.gravityrun.descriptors.ShipDescriptor
-keep class com.revicostudio.gravityrun.descriptors.Ships
-keep class com.revicostudio.gravityrun.game.galaxies.Galaxies

-keep public class com.badlogic.** {*;}

Answer 1

如果组件（Activity，Services或BroadcastReceivers）类有这个问题，那么这没关系。

Proguard不会混淆组件的名称。

如果你正在考虑定义为

的类

-keep class com.revicostudio.gravityrun.playerdata.PlayerData
-keep class com.revicostudio.gravityrun.playerdata.SettingsDescriptor
-keep class com.revicostudio.gravityrun.playerdata.ShipStatus
-keep class com.revicostudio.gravityrun.descriptors.ShipDescriptor
-keep class com.revicostudio.gravityrun.descriptors.Ships
-keep class com.revicostudio.gravityrun.game.galaxies.Galaxies

由于keep选项，因此无法更改其名称。

尝试删除-keep public class * { public protected *; }行

Answer 2

某些时间类名称混淆不起作用“butterknife” 因此，在您的proguard文件中添加以下规则。

# Butterknife
-dontwarn butterknife.internal.**
-keep class butterknife.** { *; } 
-keep class **$$ViewInjector { *; }
-keepclasseswithmembernames class * {
    @butterknife.InjectView <fields>;
}
-keepclasseswithmembernames class * {
    @butterknife.OnClick <methods>;
    @butterknife.OnEditorAction <methods>;
    @butterknife.OnItemClick <methods>;
    @butterknife.OnItemLongClick <methods>;
    @butterknife.OnLongClick <methods>;
}

注意：仅在使用“butterknife”时才使用上述规则。

Answer 3

Butterknife的旧指令定义了proguard的代码导致了这个问题，如果你使用的是butterknife和版本7之类的旧版本，请确保你没有在你的计划规则中使用这一行

-keepnames class * { @butterknife.Bind *;}

这导致所有类名都不会被混淆。

使用下面的配置为butterknife，与其他建议相比，更好，未来证明。

# ButterKnife
-keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class **$$ViewBinder { *; }

-keepclasseswithmembernames class * {
    @butterknife.* <fields>;
}

-keepclasseswithmembernames class * {
    @butterknife.* <methods>;
}

如何告诉ProGuard混淆方法和类名？
