In your the activity you launch from your first button:

@Override
public void onBackPressed()
{
// Close this activity...
}

(requires API level 5 or higher)

or

@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if (keyCode == KeyEvent.KEYCODE_BACK)
{
// Close this activity...
return true;
}
return super.onKeyDown(keyCode, event);
}
