How to run a program before answer a call in android?

Question

I want to write a program in android will ask for a password when an incoming call is detected. The program will only allow the call to be answered if the password is correct.

How should I implement that?

For example, I found a program that does this: App Lock

...but I have no idea where I should start. Should I write a service?

Thanks and regards.

You have to register a broadcast receiver in order to catch the events (call ringing, etc, etc..) and based on the various states, you can perform any operations you may want.
