title: OnBackPressed is not being called?
body: <p>I have override the <code>OnBackPressed</code> function inside my activity, but it's not being called. On other activities it's working fine.
  Here is my method:</p>
  
  <pre><code>@Override
  public void onBackPressed() {
      Log.e("back",""+1); 
      UserPage.getstate().finish();
      Intent i=new Intent(CreateGroup.this,UserPage.class);
      i.putExtra("title11","dd");
      startActivity(i);
      finish();
  }
  </code></pre>
  
  <p>This method is not being called, and the default <code>OnBackPresssed</code> is called every time i press the back button.</p>
