 R.color.red is an identifier, not the color itself. You need to call
getResources().getColor(R.color.red)

1. How to kill application

I started a sample application and called finish() method when user clicks
the button.
Then it is showing the android home screen and called the onDistroy() method
also.
But if i am executing the 'ps' command in android shell still it is showing
the pid of my application.
What is the meaning of finish()?
Is it not terminate the process?
 if not how can i terminate the process(we can do kill -9 pid in android
shell but i want programmatic approach)
