title: Adding camera icon to the action bar in android
body: <p>In menu_main.xml, </p>
  
  <pre><code>&lt;item
  android:id="@+id/camera" 
  android:title="camera"
  android:icon="@drawable/cam"
  android:showAsAction="always" /&gt;
  </code></pre>
  
  <p>I can see camera option on my menu(hardware) button click but i can't see icon in action bar.
  Do I need to change any action bar settings?</p>
