title: Xamarin Forms app unhandled exception debugging on Visual Studio
body: <p>This is a general question, I am not posting any code as the problem is not in the code (but you can download the entire project her in case you find it useful: <a href="https://developer.xamarin.com/samples/xamarin-forms/WebServices/OAuthNativeFlow/" rel="nofollow noreferrer">native authentication flow in a Xamarin.Forms application</a>. If I am breaking some community rule please forgive me, if you can help thanks for I could not find an answer elsewhere.</p>
  
  <p>Visual Studio 2015. Xamarin Forms cross platform PCL application.
  The code builds and runs just fine on both VS android emulator and when deployed on a android 6.0 Samsung 815T device. Same code breaks with unhandled exception when deployed on android 7.0 Samsung SM-A510F device. Again this is NOT the problem but the only hint I get is this:</p>

  <p>I am used to debug web application where unhandled exceptions are relatively rare and new to mobile development. Since I started studying Xamarin development I am systematically facing with this kind of unhandled exception.
  Please note I can debug the application and hit breakpoints but that does not help a lot when the only information I get from the debugger is always "unhandled application". I guess I am missing the big point here so any hint
  would be appreciated.</p>
