title: Can't login to Facebook using WebView Android
body: <p>This may seem like a similar question in Stackoverflow but it's not because all the solutions there didn't work.</p>
  <p>Facebook announced that they will not be supporting to login to Facebook using native WebView and use their SDK instead. However, my app is a browser app and I can't use their SDK just for this. Yes, I tried using a popup window to log in but it doesn't work for all websites, some websites don't open Facebook login in a popup but instead on the same page.</p>
  <p>The weird part about it is that there are many apps on the app store that use WebView and they can log in with no issues while I'm getting this error:

  I tried changing the user agent, but it didn't work. I tried using Chrome Custom Tabs but I don't really know to catch the callback when the user has logged in Chrome's tabs then continue in my webview.</p>
