title: Android webview doesn't load the last page when I tap home button
body: <p>I made a webview app for android on xamarin.</p>
  
  <p>But When I tap Android Home button, it closes the app, and when i open it again, it loads the main page, not the last page.</p>
  
  <p>How to make when i touch my App it resumes the latest page? maybe without loading page again?</p>
