title: Android: return to main activity problems
body: <p>In my main activity I have a menu and when a menu option is selected an Intent is created and a new activity is started.  When that activity completes the process should return back to the main activity and all its previous states according to the ActivityLifeCycle.  </p>
  
  <p>I notice that when it returns back to the main activity, nothing is accessable and the screen dims.  I can only get back to what I expect when I press the menu softkey.  </p>
  
  <p>Has anyone experienced this issue before?  Feedback would be appreciated!
  Code sample below:</p>
  
  <pre><code>@Override
  protected void onResume(){          
      super.onResume();
  }
  
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
      MenuInflater inflater = getMenuInflater();
      inflater.inflate(R.menu.main_menu, menu);
      return true;
  }    
  
  @Override
  public boolean onOptionsItemSelected(MenuItem item) {
      // Handle item selection
      switch (item.getItemId()) {
      case R.id.menu_settings: 
          return true;            
      case R.id.menu_decks:
          Intent launchDecks = new Intent(this, stackDecks.class);
          startActivity(launchDecks);             
          return true;        
      case R.id.menu_exit:  
          this.onDestroy();
          this.finish();
          return true;
      default:
          return super.onOptionsItemSelected(item);
      }
  }   
  </code></pre>
