java - 如何告诉 ProGuard 混淆方法和类名？

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。仅更改变量名称。

它们中的大多数不会像 Activity 这样扩展类；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 来检查结果。

由于使用 GSON，一些类被排除在外，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。

如果你正在学习定义为的类

-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，它们的名称也不能更改。

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