source code from APK

Question

I have searching in search Engine regarding convert dex file to jar file but I got failure to find dex2jar file in code.Google.com

I have getting basic idea from here.

Answer 1

I too had the same issue, Thus I downloaded my file from here.

While the file is downloading, go to your .apk file. Rename the .apk to .zip and extract zip file (which was apk once) inside a new folder.

Now as the file is been downloaded "dex2jar-0.0.9.15.zip". Extract this file inside new folder you just create and you will have a folder "/dex2jar-0.0.9.15".

Copy your "classes.dex" file from new folder to "/dex2jar-0.0.9.15" and now open Terminal and switch inside the /dex2jar-0.0.9.15 folder. And run command

tamta@tamta:~/new_folder/dex2jar-0.0.9.15$ ./d2j-dex2jar.sh classes.dex

This will create a file classes-dex2jar.jar for you inside the same folder.

Until now you had .dex file known as Dalvik Executable. If you use apktool you only get .smali , which is also not in a understandable form, So now we use "JAVA Decompiler" but we can understand JAVA and to convert do the following.

Goto Download Link

And download JD-GUI.

As you open JD-GUI:

goto folder
/new_folder/dex2jar-0.0.9.15

and open: "classes-dex2jar.jar"

Now again goto >file>Save All Sources

and save the file with the name src.

Now extract src, and enjoy reading android source code.
