Seek for help about Android Programming
<p>I am here seeking some help. 
I am beginner of Android and there are so many things I confused. 
For now, I want to know how to control system resources and services like bluetooth, SMS, phone contacts etc. 
Honestly, i want to know how or what to do to control sms usage based on user behavior, block incoming call or change it to auto vibrate mode without user noticed like that. 
Actually, I want it for my assignment about context aware access control paper. 
I choose Android for implementation but i am afraid i 
couldn't submit my paper in time if i study android from the beginning and all by myself.
Tutorials (especially with full sample code) would be fine for me.
No offense but I want to avoid errors.
I feel my head becomes swollen whenever "force close error" show as I need it urgent.
Thanks in advance! 
Cheers!</p>
