is actually two commands:

1: Run (win+r)->cmd, navigate to the Apktool folder, and enter the following command:apktool.bat d-f cmcc.apk CMCC

2: Navigate to the directory where Dex2jar.bat is located, enter Dex2jar.bat classes.dex

Here is a detailed explanation:

Start anti-compilation ~

First, through the APK anti-compilation to get the program's source code, pictures, XML configuration, language resources and other files

1.1 Put the anti-compilation apk into the Apktool folder

1.2 Run (win+r)->cmd, navigate to the Apktool folder and enter the following command:apktool.bat d-f cmcc.apk CMCC

Explanation: Where CMCC is to decompile the apk name, the last CMCC is the name of the folder generated after the anti-compilation, the size of the space to write to the line

After the carriage return we will find that has been executed, now look at the folder more CMCC this file

Now we can find the resource files we need in the CMCC folder, XML files and pictures and so on.

Second, get Java code

2.1 The APK suffix to be deserialized will be changed to. rar or. zip, and extracted to get the amount of Classes.dex file (it is the Java file compiled and then packaged with the DX tool)

2.2 Put the acquired classes.dex into the previously extracted tool dex2jar-0.0.9.15 folder

2.3 Locate the Dex2jar.bat directory at the command line, enter Dex2jar.bat Classes.dex.

Now we can find a Classes_dex2jar.jar file in the Dex2jar directory.

2.4 Now open the jar file by Jd-gui.exe in the Jd-gui-0.3.5.windows folder, File->open file to find Classes_dex2jar.jar

Done!

By the way: if you want to repackage the anti-compiled files into an apk, you can: Enter apktool.bat b CMCC(you compiled the folder).

After that, you can find 2 more folders under the previous test file:

Build

Dist (contains the packaged apk file)
