title: Restore history and current page on resuming webview
body: <p>I have a webview that I am navigating within. I have implemented go back and go forward. My problem is that when I return to the webview after visiting another activity, the history is lost i.e. the webview starts from the first url.</p>
  
  <p>How do I code it so that after I call finish on the webview to swap to another activity on returning to the webview, the WebBackForwardList is restored and I am taken to the page I was on when I left the webview?</p>
  
  <p>I have tried overriding onSaveInstanceState and onRestoreInstanceState using webview.save/restoreState(bundle) but with no success.</p>
  
  <p>I have achieved returning to the last page by saving the last url in preferences, but have been unable to restore the entire history.</p>
