I know this is irrelevant, and hope this is not too much.. but can someone guide me how to decompile and recompile APKs?
Or show me a guide to it? Thanks thanks!!
Download apk tool. search from google. It contain a .zip file, unzip it and copy to a place easy to find, for example in C: root directory.
Copy the apk you wanted to decompile to the root directory of the apk tool. Assume your directory is C:\APKTool\, then open cmd from start-run-cmd-enter.
On the command prompt, type "cd c:\apktool" and press enter.
After that type "apktool d com.whatsapp.apk (just example, your apk name can be something else, just type the apk name).
Wait for a while and when it done you should get a com.whatsapp folder in your apktool directory. Open the file you want to edit and edit it. After u done with editing, compile the apk by typing "apktool b com.whatsapp".
Wait and you'll get 2 folders in your apktool directory. called build and dist. Sign the apk u have decompiled with any apk signer tool, I use sign apk tool for this.
Just google it and unzip the file to C:\ location and put your apk from dist folder in apktool to any place u want it to be. open cmd again, type cd "C:\signapk(your sign apk tool folder name)", press enter and type "java -jar signapk.jar certificate.pem key.pk8 your-app.apk your-app-signed.apk (for example java -jar signapk.jar certificate.pem key.pk8 c:\com.whatsapp.apk c:\com.whatsapp-signed.apk.
Now uninstall your whatssapp from your phone and install the apk you have compiled and done!!
