title: WebView textarea doesn't pop up the keyboard
body: <p>When I display a <code>WebView</code>, I don't see the soft keyboard popping up. The hard keyboard also doesn't work!</p>
  
  <p>What are the usual shortcomings.</p>
  
  <p>The code which I use to access the <code>WebView</code> is:</p>
  
  <pre><code>package com.example.blahblah;
