title: How to update recyclerview using Intentservice without data duplicate
body: <p>I have a recyclerview getting data with http request using Intentservice. I have a button to update my recylcerview adapter. When i push this button data updates and it's seems alright. But when i push this button and change screen orientation, number of rows in recylcler view doubles.</p>
  
  <p>I have this in my manefest:</p>
  
  <pre><code>        &lt;activity android:name=".MainActivity"
          android:configChanges="orientation|screenSize"&gt;
  </code></pre>
  
  <p>So seems like android shouldn't create a new activity with changing orientation and he doesn't when i just change orientation without pushing update button. Anyone got some ideas about that? Thanks.</p>
