title: Changing the Android Webview hash without reloading page
body: <p>I'm got a custom webview setup which is working pretty well, but I'd like to be able to either:</p>
  
  <p>1, change the url hash without the webview reloading the page (it would lose the state of my js app)</p>
  
  <p>2, call some js that sits within my web page from within android.  I can't change any JS within the site, unfortunately, so can't custom write any js to put on the site especially for the job, the only stuff I have control over is the Android app.</p>
  
  <p>Can anyone think of a way of doing either of these?  </p>
  
  <p>Thanks in advance.</p>
  
  <p>M</p>
