I'm really stuck trying to connect an Android app to Office 365.
Has anyone been successful to do this in a Xamarin app?
There is not many samples or documentation out there and would really appreciate any help.
I'm in first step of authentication, using this sample:

I got this exception

After that I have updated MainActivity to inherit from Activity and after the authentication I got a web view telling me that the website with the url of my Active Directory in Azure is not available. When the app is closed I got this exception.
