body: <p>How do I create a settings screen? 
  Should I use <em>PreferenceActivity</em> or  <em>PreferenceFragment</em>?</p>
  
  <p><strong>Note-</strong> Documentation wasn't helpful</p>
  
  <p>What I've already tried:</p>
  
  <ol>
  <li>Using <em>PreferenceActivity</em> but couldn't implement a simple toolbar in it.</li>
  <li>Using <em>PreferenceFragment</em> but was too complex to understand. </li>
  </ol>
  
  <p>What I want is a simple implementation using <em>PreferenceFragment</em></p>
