Easy Trick To Decompile, Recompile, and Sign Most .APK Files – A very fundamental trick that most Android users who want to not just owning their device for daily usage must know, how to decompile any .apk files then recompile it again -with modifications of course- followed by signing it for easy implementation.
But then comes the question on how to do that? Is that task requiring advanced programming / coding technique?
Well, lets thank to an XDA member “Yorzua” who has shared a nice easy way to do that task with a little help of Apktool, Openssl, Signapk.jar and even a simple tool like Notepad++ or for me, I prefer Notepad2.
Yet, he also shared a complete tool kit to do the task but remember that it works on most .APKs and may not work in some complex .APKs.
As this trick is really a must-know for a themer, tweaker, or simply an Android end-user. So you better bookmark it for further usage.
Decompiling APK
The command is:
apktool d
The apk name can be whatever name you give.
Recompiling APK
Once you’ve made some modifications to the .APK, simply use following command to re-compile .apk:
apktool b
Signing Your APK
The final step you’ll need to do is signing you APK. Use following command:
java -jar SignApk.jar testkey.x509.pem testkey.pk8
