Android-android 怎么实现只混淆自己的代码，而不混淆第3方jar包

当项目中有第3方jar包时，怎么实现混淆打包，而不对第3方包混淆 在项目中有第3方包时打包出错日志： [2012-06-14 14:14:28 - ] Proguard returned with error code 1.

能过滤掉警告信息。

但是治标不治本，打好的包，在实际运行中用到过的第3方包类库时，均报空指针。

方案二：不使用-ignorewarnings 添加-dontwarn java.awt.datatransfer.Transferable.** 警告信息并没有减少，打包会失败。

android混淆打包 功能不能用

ProGuard来进行混淆打包，大大的优化Apk包的大小。

但是注意ProGuard对文件路径的名名很有讲究，不支持括号，也不支持空格。

在混淆过后，可以在工程目录的proguard中的mapping.txt看到混淆后的类名，方法名，变量名和混淆前的类名，方法名，变量名。

　　在使用Eclipse新建一个工程，都会在工程目录下生产配置project.properties和proguard-project.tx。

　　# To enable ProGuard to shrink and obfuscate your code, ment this (available properties: sdk.dir, user.home): 　　#proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt 　　# Project target. 　　target=android-10 　　project.properties用于配置Android工程的一些属性，#号的话表示当前行是注释，这里的proguard.config就用于指定ProGuard的混淆配置文件，并对使用release方式打包应用程序时开启代码混淆功能。

对于是否是使用release方式打包，和AndroidManifest.xml中application的android:debuggable属性有很多关系。

如果该值为android:debuggable="true"，那么最终就是debug方式打包。

最明智的方式就是在AndroidManifest.xml并不显示的指定它，而是是打包工具在打包时来决定它最终的值。

对于ant就是ant release或ant debug。

而对于直接在Eclipse中使用run 或debgu来打包的话就是debug,使用export的话就是release. 　　proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt 　　这里的话指定了混淆的基本配置文件proguard-android.txt，和混淆的个性化配置文件proguard-project.txt。

Android 混淆出问题了，求教

您好，我在别的论坛也看到您的问题，很高兴为您解答： duplicate definition of library class [.http.SslError] 看来不是混淆问题，你的包自身就有多余的吧？结果是相同的类冲突了。

在proguard.cfg加上忽略警告的代码，就可以了。

如果我的回答没能帮助您，请继续追问。
