以前做的手机项目,并没有要求混淆,一直没时间去看,等到做了平板,有混淆的需求才要硬着头皮去看混淆到底是如何工作的,以及如何混淆验证成功,参考一篇博客,讲的非常详细,而且每一步都写的非常好,再次感谢作者的辛勤劳作:关键是要先准备好两个工具,细节这篇博客讲到了,我说下我遇到的坑和问题:
1.dex2jar工具(下载地址:http://code.google.com/p/dex2jar/),开源的反编译的项目,可以将apk文件转成一个jar包
2.jd-gui工具(下载地址:http://jd-gui.softpedia.com/)。这个工具挺厉害的,可以将jar包反编译成具体的java代码
=================分割线========================正式混淆工作有可能遇到的问题如下======================================
一.准备好了这些工作,就可以开始进行混淆的工作了,第一步,当然是找到你的android工程,按照上面的连接,给工程添加混淆的设置,如下图:
这一步有可能你在project.properties文件如何添加混淆的文件,一共有两种方式,一种是新建一个proguard.cfg这种方式我没试过,不过高版本的sdk,建议还是使用proguard-project.txt每个工程默认都会有一个. 需要注意的是你需要在环境变量里面添加sdk的工程目录,如下图:
二.上述前期工作准备好后,就要在proguard-project.txt文件里面新建混淆的规则了,一般的原则是在libs的第三方jar需要保留,不进行混淆,默认的一些谷歌官方建议保留的activity也是需要保留的,这些文档都有,如下图我的工程里面的jar包,第一次进行签名打包时候,就遇到下面这么多错误:

三,以下是我工程完整的proguard-project.txt,你需要结合自己使用到的工程jar包,和具体的报错信息,进行处理就可以了,总体的原则就是那里出错,就告诉他不要再警告,如果第三方达成jar包还是有错的话,就将第三方具体的类和class路径所有的类都keep,不进行混淆,这样之后就不会有问题,文件如下:

花了好长时间终于解决了,过程虽然很艰辛,但是解决了,欢迎拍砖,有问题可以问我,很高兴为你解答.
