好吧,更新一下,我发现对于android6这三个版本用的是同样的方法,所以在android6里面3个脚本dump出来的应该是同一个东西了?
不过还是有两个问题向请教一下。。
- 实际上我试过几次之后感觉好像有时候dump出来的内容多有时候比较少,不知道是什么原因
- 在dump的途中我发现有好几个size为292的文件,我注意到dump是以文件大小当作名字的,这样子会不会导致一个覆盖其他的文件?

你好,你说的乐固加固dump出来的dex打开里面方法都是nop的问题,是因为加固工具对方法做了抽取的并加密单独存放的缘故,一般是商业级别的加固。这些方法会在运行时解密,这个脚本不能还原抽取的方法,需要自己dump方法运行时的isncode,再patch到dump出来的dex文件,进行方法还原,Android4.1可以dalvik/vm/oo/Resolve.cpp中dvmResolveClass函数可以dump出inscode,Android5.1及以上使用ATR模式运行的可以在art/runtime/class_linker.cc中的ClassLinker::LoadClassMembers函数中dump出inscode。
另外你说的关于文件大小一样导致文件覆盖的问题,我之前用大小加时间戳的方式命令,把文件取出来对比,相同大小的文件是一样的,当然不保证所有的APK都是这样的情况,你可以把地址打出来看是否一样,或者加上时间戳。
