title: Opening WebView in background
body: <p>This is the first time I ask something, so if there is something wrong just tell me and I´ll try to fix it ASAP.</p>
  
  <p>We have a customer that wants us to login in their servers with a native Android app, but without giving us a custom way to do this. They want us to use the current website they have to log and, after authentication takes place, retrieve within the browser a XML which contains the data we need. After that, use the data in the native app. All of this with the user not knowing/seeing that a browser is being used. A total mess IMHO.</p>
  
  <p>Of course, I have never tried this approach in the past and my first tests make me feel like this is impossible (or extremely difficult) to achieve. Whenever I try to load the URL in a hidden WebView the default browser pops up showing the website. </p>
  
  <p>My main question is, is it possible to load a webview and work with it (invoke javascript, etc...) in the background?</p>
  
  <p>Thank you.</p>
