Android中proguard混淆第三方jar包

本文引自：http://blog.csdn.net/ma969070578/article/details/9465439。

对于大部分第三方的Jar来说，都会提供混淆代码（U盟等）。有些没有提供的，感觉还是有些帮助。

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progurad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.** { *; }

 

7.微信

 注意
如果需要混淆代码，为了保证sdk的正常使用，需要在proguard.cfg加上下面两行配置：

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

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

 

8.项目中有新浪微博weibo.sdk.android.sso.jar怎么办？

-dontwarn android.net.http.**

-keep public class android.webkit.WebView {*;}-keep public class android.webkit.WebViewClient {*;}-keep class com.weibo.net.** {*;}
