title: Webview submit form when click "Go" button
body: <p>I'm developing an android app. It uses WebView to load a form with following component:</p>
  
  <ul>
  <li>Username textbox</li>
  <li>Password textbox</li>
  <li>Submit button</li>
  </ul>
  
  <p>When I fill all fields then click submit button, data will be validated, but when I click "Go" button from android keyboard, nothing happens. How I can resolve it?</p>
  
  <p>P/S: I'm debugging on an android 4.4.4 devices.</p>
