is there a default back key(on device) listener in android?

How can I respond to the physical back button in my Android application?
Like a listener of a sort.

I want to do things when that button is pressed!

If I understand your question, simply override onBackPressed() in your Activity for API 5+.

@Override
public void onBackPressed() {
    super.onBackPressed();
    // Do something
}
