title: Android: Start main activity when pressing Back Button
body: <p>I need help with this activity thing.. I have a main activity and when a button is clicked a new activity starts and the main activity finishes. What I want is to start аgain the main activity when the back button is pressed in the second activity. Or if you can tell me a another way to refresh the main activity when I turn back from the second, without adding a new activity in the stack. I will really appreciate your help. Thank you :)</p>
  
  <p>P.s: I need to tell you that my activity extends ActionBarActivity, not Activity so I'm not pretty sure how to override onBackPressed() if I need to.</p>
