Decoding .apk files, step-by-step method

Procedure for decoding .apk files,

step-by-step method:



Step 1:

1. Make a new folder and copy over

the .apk file that you want to

decode.

2. Now rename the extension of

this .apk file to .zip (e.g. rename

from filename.apk to filename.zip)

and save it. Now you can access

the classes.dex files, etc. At this

stage you are able to see

drawables but not xml and java

files, so continue.

Step 2:

1. Now extract this .zip file in the

same folder (or NEW FOLDER).

2. Download dex2jar and extract it to

the same folder (or NEW FOLDER).

3. Move the classes.dex file into the

dex2jar folder.

4. Now open command prompt and

change directory to that folder (or

NEW FOLDER). Then write

d2j-

dex2jar

classes.dex and press

enter. You now have the

classes.dex.dex2jar file in the same

folder.

5. Download java decompiler, double

click on jd-gui, click on open file,

and open classes.dex.dex2jar file

from that folder: now you get class

files.

6. Save all of these class files (In jd-

gui, click File -> Save All Sources)

by src name. At this stage you get

the java source but the .xml files

are still unreadable, so continue.

Step 3:

Now open another new folder

1. Put in the .apk file which you want

to decode

2. Download the latest version of

apktool AND apktool install

window (both can be downloaded

from the same link) and place them

in the same folder

3. Download framework-res.apk and

put it in the same folder (Not all

apk file need this file, but it doesn't

hurt)

4. Open a command window

5. Navigate to the root directory of

APKtool and type the following

command:

apktool if

framework-res.apk

6. apktool d

myApp.apk (where

myApp.apk denotes the filename

that you want to decode)

now you get a file folder in that

folder and can easily read the apk's

xml files.

Step 4:

It's not any step just copy contents

of both folder(in this case both new

folder)to the single one

and enjoy the source code...
