I am developing an application that requires logging in facebook and for this I am using the following code:
https://github.com/HoussemDellai/Facebook-Login-Xamarin-Forms
It works perfectly when I am connected to the internet via wifi, but when I connect through 4g I receive the following message and then the device stops. I really do not know what the error is, as with the wifi it works correctly.
Facebook code is the same as github demo
Finally I found the solution and is that when you access facebook from an Android browser, you are redirected to:
https://web.facebook.com/connect/login_success.html#access_token= < access_token >
It is only a question of replacing the "web" with "www" in the url.
