The following tutorial will show how to
easily extract, modify or edit and repack
Android .apk app files on your PC
computer.
Have you ever wished you could modify
an Android app to add or remove or modify some features like pictures of
colors of value strings? Then this tutorial
is an easy way for you to achieve this.
With thisHowTutor tutorial, will you
surely be able to customize any Android
game or App to your taste.Required Tools: There are two files needed for this
exercise, and these files are available
freely n the internet, thanks to the
makers. These files are:
1. APKTool, needed to decompile and
recompile APK files, and 2. SignApk, which is needed to sign the
recompiled APK files.
These two files have been zipped in one
folder and is downloadable here.
Steps:
1. Download the zip folder above and extract it into a folder automatically
named APKTool. This folder will contain
four sub-folders, viz files, compiled,
decompiled, and signed.
Using thhe 4 folders:
a. Files: Put the Android APK you want to modify in here. In our tutorial, lets name
it MYAPP.apk
b. Decompiled: The decompiled aok
content files go here automaticaly. You
can pick them and edit the files after
decompiling and save each back in here. c. Compiled: After you have edited and
recompiled the apk files from the
decompiled folder, the unsigned APK file
goes here automatically. The unsigned
apk file will need signing before being
useful. d. Signed: The finished apk file, after
signing with the steps below
automatically goes here. You can now use
and install the finished apk after signing.
NOTE: There would be other files in the
APKTool folder asides these sub-folders. One of them is named Command Prompt.
2. Launch the Command Prompt file, and it
will open a windows command prompt
where we carry out the following steps.
3. EXTRACTION: Type the following
command in the command prompt: Code: Select all
apktool d files/MYAPP.apk decompiled/
MYAPP
MYAPP.apk being the app you are editing.
This command will extract the original
MYAPP apk files contents into the decompiled sub-folder: 4. EDITING, MODIFYING: You can now
browse into the decompiled folder and
replace anything and edit anything you
want to edit accurately. Replace pictures,
change values etc.
5. REPACKING, ZIPPING IT ALL BACK: After saving all your modifications, run the
following commands in the same
command prompt:
Code: Select all
apktool b decompiled/MYAPP compiled/
MYAPP.apk This command will bind together all the
modified apk contents into one new
MYAPP.apk andoid app file in the Compiled
sub-folder.
6. FINALLY, SIGNING: As stated earlier, the
final apk is unsigned and is useless as such. Now we take advantage of the
second downloaded file SignApk to sign it.
So, in the same command prompt
window, type:
Code: Select all
java -jar signapk.jar certificate.pem key.pk8 compiled/MYAPP.apk signed/
MYAPP.apk
Thats it! Eureka! The final product, a
signed and modified MYAPP.apk will be
located in the Signed subfolder. Now its
ready for use! Now you can transfer it to your Android
phone or tab, and enjoy!
