odex 转 dex

提取系统apk：
下载jar：https://bitbucket.org/JesusFreke/smali/downloads/
smali.jar和baksmali.jar

1.执行：1.java -jar baksmali.jar de temp.odex
会报错，把系统framework文件夹的东西pull出来

把arm里面的文件拷贝到上一层目录(其实应该不用也可以，因为我不熟悉baksmali的其它参数)
再次执行第一步命令就可以看到out目录下有smali文件了
2.java -jar smali.jar a out -o temp.dex
在当前目录会生成dex文件
接下来就转jar看代码了。

整个下来工作并不多，但是这里面很多坑。

第二种方法：
从官网下载rom包，然后dat解包，SVADeodexerForArt工具合并apk，这个简单方便
