I will provide you a .apk file and some info regarding how it works. I will need you to study it in more depth, it's not a complex app. It's actually quite simple.
I will need then to edit some of the apk and compile it back again. We are having some issues here since it's using .smali files.
I will explain further once project awarded.

Depends on how the apk was compiled, we could retrieve the information you need. But that can only be known after reviewing it. We will want to know details of work before awarding.
