-gui folder is opened, and the tool is opened before the Classes_dex2jar.jar file, you can see the source code, the effect is as follows:(The name of the class file and the name of the method inside will be a,b,c ...). Style naming).By decompile, you can learn about the third-party library files that the app uses, how the code is written, and so on.
