Android Tutorial Decompile & Recompile .apk without a tool like 'AdvancedAPKTool etc'

[Ted2 38.9k Donor]

Heyy,

 

Yesterday someone tried to hack a game & he needed to see .smali files but I couldn't exactly find a tutorial from this form to link to him. There are tools etc, but yea that's why I'm writing one .

 

What you need first, are the correct files & installation

 

How?

https://ibotpeaches.github.io/Apktool/install/

Better tutorial for mac: http://macappstore.org/apktool/

Also you will need JRE installed; http://www.oracle.com/technetwork/java/javase/downloads/index.html

 

After that it'll look something like this: (SignApk folder is  something I created by my own)

 

 

 

As you can see, I already did put a .apk in there:  dtm.apk

That's the one we'll decompile

 

What we have to do now, is locate to this folder on Terminal or CMD

 

CMD: SHIFT + right mouse button --> Open command promt here or you can 'cd' to it, not sure how on windows.

Terminal: cd /whereyoulocated the apktool folder, mine = cd /users/joey/desktop/apktool

 

After you located to your apktool folder.

 

There are only 2 simple commands you need to know:

apktool d 'nameofapk'.apk ---> decompiling
apktool b nameofapkyoudecompiledasfolder ---> recompiling

In my case:

apktool d dtm.apk
apktool b dtm

lemme show you how it will looks like after decompiling: (redline is decompiled .apk)

 

 

So, imagine you did some changes in the smali files or png files or whatever , you wanna recompile it back to .apk ofcourse, how?

 

well in my case i type in terminal:

 apktool b dtm

It will look like this: 

 

 

What you have to do now:

 

Openup the decompiled .apk folder, in my case 'dtm' & go to 'dist'

 

Here you'll find the recompiled .apk, you only need to sign the .apk...

 

That's why I created a SignApk folder in my apktool folder, but you can also download 'Zipsigner' from playstore.

 

How do I sign the .apk?

 

This is my SignApk folder, unzip it in your apktool folder: http://www73.zippyshare.com/v/lRQPtsWK/file.html

 

After you've unzipped it, copy apktool + apktool.jar from your apktool folder into the SignApk folder.

 

I copy the recompiled apk to my SignApk folder

In my SignApk folder I created a .txt doc with the command to sign .apk

It's this command:

java -jar SignApk.jar testkey.x509.pem testkey.pk8 apkname.apk newapkname.apk

I'll have to locate using Terminal first:

In my case: cd /users/joey/desktop/apktool/signapk

 

Then I run this command:

java -jar SignApk.jar testkey.x509.pem testkey.pk8 dtm.apk dtm_signed.apk

It will look like this: (red line is signed apk)

 

 

 

Hope it's a bit clear!

 

Goodluck!

Yes you defenitly can

You may have to give chmod premisons, but they are saying that on the apktool site too I thought.
