I have seen a lot of guides on how to decompile with Apk Tool, but none are noob friendly, so I thought I would post this.
What You Need:
Java JDK/JRE 32 bit
Super Basic Cmd/terminal knowledge (My 5 year old brother can handle this)
Download Apk Tool Here: (Must be this one)
First you need to extract that zip folder to anywhere you choose, preferably on root of c/drive E.g: C:/android/apktool extracting the files to 'apktool' folder.
Now copy the apk you would like to mod into your Apk Tool folder.
Open up your Command Prompt by going to:
Start -> run -> type : Cmd
Your cmd will probly look like this.. C:\users\yourname> so type in cd.. (Yes include the '..' and press enter after you type each command.) this will get you to back directory so now you will see C:\users> so type again cd.. you should now see this: C:\> now type in: cd 'apktoo'l/'directory' for me it looks like: cd android/apktool now you should see: C:/android/apktool> and you are in the apktool directory
Now that you are in directory we need to install the device's framework to your system for it to compile correctly so type this:
apktool if framework-res.apk
Remember: Devices like HTC / Samsung / Huawei have other frameworks that are used in their apps too, sometimes you need to install them too.
This will install the devices framework to your system. (need to do this)
Now to decompile the apk you want to edit, type this:
apktool d framework-res.apk framework1
apktool d music.apk music
music.apk is the apk your decompiling
music is the folder you're creating for the decompiled apk
Now go about your business
Now to recompile your new apk type this:
apktool b music music-new.apk
apktool b framework1 framework-res-new.apk
framework1 is the folder with your edited files
framework-res-new.apk is your new apk file
We are NOT done just yet, we cannot use the new apk's... we have to take what we did and add it back to the original apk file to keep proper signature
use something like 7zip, take the 'resources.arcs' file and any other xml files you edited out of the "-new" apk and copy them into Original apk
Your new modded APK is now ready, Congrats!
If you get Java errors see here.
If you recompile fine but doesn't install " App couldn't not be installed " see here.
Good Luck Guys!
