You probably wont be able to add any, you can change the current ones by editing the apk, signing it then installing it. Once you open up the apk (with 7zip, winrar etc.) look inside the drawable-hdpi folder. Thats probably where the emoticons are kept.
I can help if you need.
You might want to check out these custom whatsapp's by yorzua :
I used 'Formatter' to rename (whatsapp) .apk file into .zip did required changes (replaced one .png smiley file) & again renamed it into .apk
But then, I'm not able to install it (even after uninstalling previous version). An error saying 'Application not installed' shows.
How can I modify .apk files (in terms of replacing only the smiley image files) & repack it into proper .apk file so that I'll be able to install it without any error?
Please help me..
