title: Should "android: onOptionsItemSelected" return true or false
body: <p>In onOptionsItemSelected... I saw some code that are different in the switch block.</p>
  
  <p><strong>Case 1 (Normally seen)</strong></p>
  
  <pre><code>public boolean onOptionsItemSelected (MenueItem item)
         switch (item.getItemId()){
               case R.id.item1:
               startActivity (new Intent (this, PrefsActivity.class));
               break;
         }
         return true
  </code></pre>
  
  <p><strong>Case 2 (unsure of why it's set up this way)</strong></p>
  
  <pre><code>public boolean onOptionsItemSelected(MenuItem item) {
         switch (item.getItemId()) {
                 case MENU_NEW_GAME:
                 newGame();
                 return true;
         }
         return false;
  </code></pre>
  
  <p><strong>My Question</strong></p>
  
  <p>What are the differences between Case 1 and Case 2?</p>
