REQUIREMENT

Apktool [click here to download][Thanks to brut.all for this apktool]

Java JDK/JRE 32 bit [please google it guy's]


Preparation before WORKING

Process :-

1) now install the java in your pc/lappy
then copy the apktool.zip & goto directory C:/
make a folder name apktool (u can name it by watever u like)
now goto that folder & paste the zip
extract that zip there...


2) now copy the .apk or jar file which u wnt to decompile
& paste it on apktool folder.....
also copy the framework-res.apk of that rom &
paste it on that folder..

Decompiling application


3) now open 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

cd apktool (and you are in the apktool directory)


4)Installing Framework

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

this will install the devices framework to your system (need to do this)

5)now to decompile the apk you want to edit.. type this:

apktool d music.apk mod

music.apk is the apk your decompiling
mod is the folder you're creating for the decompiled apk

do whatever you want to do with your apk...

NOW RECOMPILING

6)now to recompile your new apk type this:

apktool b mod music-new.apk


mod is the folder with your edited files

music-new.apk is your new apk file

Now we are NOT done... we cannot use the new apk's...

now make two separate folder a & b
copy-paste the original music.apk in 'a'
& music-new.apk in 'b'
use something like 7zip, take the 'resources.arcs' file and any other xml files you edited out of the "new-edited" apk and copy them into Original apk
now add to archive ...the origanl apk in zip format
& at the end of the file name .apk ( i mean give the file format name as .apk insted of .zip)


Now you are almost done.....:thumbup:
