1. $upzip classes_dex2jar.jar-d [Step_3]

        $upzip classes_dex2jar.jar-d [Step_3]

(4) We get a step_3 folder. We will then decompile all the. class files under this folder

1. $./jad-o-r-s java-d src step_3/**/*.class

        $./jad-o-r-s  java-d  src step_3/**/*.class

For the above parameters, it is possible to run directly./jad view, or Readme.txt view

(5) We get another src folder, which is the anti-compiled source code file.

You can also use the Jd-gui tool to view the Classes_dex2jar.jar class file directly.

If the above command does not run, see if the folder is correct.
