Default Questions about Android development
Hello, I'm a noob in the Android world so please excuse me if I'll ask a stupid questions or similar lol

Well, I have two questions:

1.- Can I make an app that "hook" the contacts list and add a little icon or text at the side of each number?

2.- I want to show some info about the number when the phone is receiving an incoming call.. What is the best/recomended way to do this? (Something like the app of the White Pages).


I hate to ask for help in forums (I like search/learn for myself), but in this occasion I'm too lost

Thanks!
