Setting up
  1. Create a folder (ex. Android apk)
  2. Paste the zipped file on the folder
  3. Extract all inside the zip
  4. Extract one_click_signer.rar to the Android apk folder
  5. Extract apktool1.4.1.rar to the Android apk folder
  6. Rename apktool.jar.rar to apktool.jar
  7. Copy and paste apktool.jar to apktool1.4.1 folder
Modifying the APK file
-  Paste the apk (ex. plapybird.apk - as seen on the screen shot) you want to edit to apktool1.4.1 folder
- Open the Command Prompt.bat
- Type apktool.bat d plapybird.apk (this step is to disassemble the apk file)
- Then a folder will created containing the files inside the apk
- Now, you can modify anything inside AS LONG AS YOU KNOW WHAT YOU ARE DOING :)
- After all the modifications you apply inside the folder, let's rebuild the apk file
- Type apktool.bat b plapybird plapybird_mod.apk
The pattern would be apktool.bat (space) b (space) [Filename] (space) [ModdedFilename].apk
Filename - the name in the original apk
ModdedFilename - the new name for the modded apk

- Then, the new apk file will be created with the Modded Filename

Signing in your APK file
You cannot install an app without signing it on Google. It can result into parsing error. But, in this tutorial, we can signed an apk file without submitting it on Google.

First, copy and paste [ModdedFilename].apk to "one_click_signer" folder

Open the one_click_signer.bat

Type the file name of your modded apk (ex. plapybird_mod.apk - as seen on the screen shot)

There should be a new apk file in the folder. This apk file will be the sign apk and it is ready to be installed

- Uninstall first the original apk installed on your phone (if it has)
- Make sure you have a backup copy of the original apk in case you want to install it

    1. No need to be a fucking cunt. Just because you're too fucking stupid to get it to work does not mean its his fucking fault.

    2. I know this is old but Dipty is right. A tutorial that is titled "learn how to modify" and literally has a step that says "you can modify anything inside AS LONG AS YOU KNOW WHAT YOU ARE DOING" is the epitome of a terrible tutorial. People obviously clicked the link because they didn't know what they were doing.

  4. Hay dude.. your artical is very usefull. but there is some errors found when im doing the prosses. so we need to install any java file reader or something like that to do this. if you can give us more info about moding apks its very usefull for me. and... can we get unlimited coins in this way?

At the point 6 of setting up what the hell you mean with "rename apktool.jar.rar to apktool.jar " ? explain it clear, it's really useless that information since the rar archive display its name only apktool.jar and if you extract it's still the same name so what we should rename? Cheers.

      now rename the .jar file you downloaded from apktool 1.2.1.jar to apktool.jar
