ProguardGui 让我的 android jar 错过了很多课程

Question

我想使用 Proguard 来混淆我的 Android jar，它有近 3000 个类，但是，当我使用 Proguard 混淆它时，我发现输出 jar 只有 1 个类！谁能帮助我，我将不胜感激！ 我在下面发布配置和输出日志

Proguard 配置

 -injars 'E:\Users\DalenRuan\workspace\Predictor_lib\predictor_lib.jar'
-outjars 'E:\Users\DalenRuan\workspace\Predictor_lib\out_predictor_lib.jar'

-libraryjars 'E:\adt-bundle-windows-x86-20140702\sdk\platforms\android-18\android.jar'
-libraryjars 'E:\Users\DalenRuan\workspace\Predictor_lib\libs\httpmime-4.1.1.jar'

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

-keep public class * extends android.app.Activity

-keep public class * extends android.app.Application

-keep public class * extends android.app.Service

-keep public final class *

您应该为您在 build.gradle 文件的依赖项中声明的每个 API 和 jar 搜索 proguard 配置。例如，如果您使用的是 fabric api，您可以从这里的文档中获取 proguard 代码 https://docs.fabric.io/android/crashlytics/dex-and-proguard.html 或者如果您在代码中使用 volley，那么您必须编写 -keep class com.android.volley.** { *; } 等等， 不要在开始时使用 -ignorewarnings 尝试使用 -dontwarn 抑制依赖项的相应错误的警告 最重要的是通过以下方式包含所有 Java 类

##Keep classes that are referenced on the AndroidManifest
-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.preference.Preference

-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.preference.Preference

#
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}
#
##support libs(cab be used more wisely)
-keep class android.support.v4.** { *; }
-keep class android.support.v7.** { *; }
-keep public class * extends android.support.v4.**
-keep public class * extends android.support.v7.**

    ##Fragments
-keep public class * extends android.app.Fragment

    -keep class com.your-packagename.**{ *; }

最后，您还可以使用 -dontnote 删除重复 jar 等消息 如：-dontnote org.apache.http.** Lastly refer the documentation here https://www.guardsquare.com/en/proguard/manual/examples https://www.guardsquare.com/en/proguard/manual/troubleshooting Thanks
