Android中proguard混淆第三方jar包及内部类

现在大部分项目都使用第三方的jar包，包括json解析的gson.jar，统计用户信息的umeng.jar，support-v4.jar等等等等，这些jar包本身基本都做了混淆，如果再用proguard混淆的话会出现错误，所以要通过-keep等方法不混淆这些jar中的内容，把到现在用过的整理下仅供参考~~

 

1.项目中有gson的jar包怎么办？

-keep class sun.misc.Unsafe { *; } 
-keep class com.google.gson.stream.** { *; } 
-keep class com.google.gson.examples.android.model.** { *; } 
-keep class com.google.gson.** { *;}

 

2.项目中有commons-httpclient-3.1.jar怎么办？

-keep public class org.apache.commons.httpclient.** {*;}
-keep public class org.apache.commons.httpclient.auth.** {*;}
-keep public class org.apache.commons.httpclient.cookie.** {*;}
-keep public class org.apache.commons.httpclient.methods.** {*;}
-keep public class org.apache.commons.httpclient.params.** {*;}
-keep public class org.apache.commons.httpclient.util.** {*;}
-keep public class org.apache.commons.codec.net.** {*;}
-keep public class org.apache.commons.logging.** {*;}
-keep public class org.apache.commons.logging.impl.** {*;}
-keep public class org.apache.commons.codec.** {*;}
-keep public class org.apache.commons.codec.binary.** {*;}

 

3.项目中有umeng_sdk.jar怎么办？

-keepclassmembers class * {
   public <init>(org.json.JSONObject);
}
-keep public class [您的应用包名].R$*{
    public static final int *;
}
把[您的应用包名] 替换成您自己的包名，如com.yourcompany.example。

如果您使用了双向反馈功能，还需要添加下面代码，以免我们自定义的UI被混淆：

-keep public class com.umeng.fb.ui.ThreadView {
}

 

4.项目中有baidumapapi.jar怎么办？

-keep class com.baidu.mapapi.** {*;}

 

5.项目中有android-support-v4.jar怎么办？

-dontwarn android.support.v4.**  
-keep class android.support.v4.** { *; }  
-keep public class * extends android.support.v4.**  
-keep public class * extends android.app.Fragment  

之前我还这样做过

-dontwarn android.support.v4.**
-keep public class android.support.v4.view.** { *; }
-keep public class android.support.v4.accessibilityservice.** { *; }
-keep public class android.support.v4.os.** { *; }
-keep public class android.support.v4.app.** { *; }
-keep public class android.support.v4.widget.** { *; }

 

6.项目中有ksoap2-android-assembly-2.3-jar-with-dependencies.jar怎么办？

-ignorewarnings
-keep class org.kobjects.** { *; }
-keep class org.ksoap2.** { *; }
-keep class org.kxml2.** { *; }
-keep class org.xmlpull.** { *; }

-ignorewarnings是忽略proguard过程中所有的警告，用了它就不必使用-dontwarn方法啦，但是用它要谨慎！

 

7.项目中的某个Activity中有webview与js交互的内部类，怎么才能不混淆这个内部类？

-keep class [某个包的包名].[含js交互的Activity]$*{
    <methods>;
}

-keepclassmembers class [某个包的包名].[含js交互的Activity]$*{
    *;
}

例如：

-keep class com.xxx.xx.XxxActivity$*{
    <methods>;
}

-keepclassmembers class com.xxx.xx.XxxActivity$*{
    *;
}

 

8.项目中有geronimo-spec-activation-1.0.2-rc2.jar怎么办？

-ignorewarnings
-keep class javax.activation.DataHandler.** { *; }
-keep class javax.activation.ActivationDataFlavor.** { *; }

 

9.项目中有微信分享的jar包怎么办？

-keep class com.tencent.mm.sdk.openapi.WXMediaMessage {*;}
-keep class com.tencent.mm.sdk.openapi.** implements com.tencent.mm.sdk.openapi.WXMediaMessage$IMediaObject {*;}
