我希望在 android apklib 文件中混淆非公共方法等，以便我可以与其他人分发 apklib 文件，而不会影响共享我的所有源代码，因为 apklib 包含源代码。

我正在采取的方法是通过在 pom.xml 中启用 proguard.cfg 来混淆库项目中的非公共方法

这是我的 proguard.cfg 的样子

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference

-keepclasseswithmembernames class * {
    native <methods>;
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

这是我在 Maven 安装时遇到的错误

不确定您是否还需要答案，但无论如何我都会给出答案，因为我遇到了类似的问题并偶然发现了您的问题......

关键是，引用 Proguard 手册：“为了确定哪些代码必须保留以及哪些代码可以丢弃或混淆，您必须为代码指定一个或多个入口点。这些入口点通常是类与主要方法、小程序、midlets、活动等"

因此，您的代码中似乎没有任何公开条目。必须有一个公共条目，否则任何东西如何使用您的库或操作系统（如 Android）如何调用您的代码。

您需要确定库的入口点是什么，然后需要确保正确使用“-keep”命令。例如，从库的 Proguard 示例中，这就是它们保持公共类的方式：

-keep public class * {
    public protected *;
}
