Xamarin.Forms Azure AAD Login Page Looses Entered User Name on Device Orientation

Question

User277909 posted

I have Xamarin.Forms application that authenticates user against Azure AAD. That all works fine but on Android, device orientation looses user name on the Microsoft authentication screen.

Here I am in Portrait mode and I have entered user name

I click on Next and land on screen to enter password. If I now rotate device before entering password and clicking Sign In, I am pushed back to screen asking for user name again and the user name I entered before is lost:

This is not happening on IOS devices, only Android.

How do I prevent this from going back to user name screen on Android? My MainActivity has already ConfigChages.Orientation attribute like below:

    [Activity(Name = "my.mainactivity"
    , Label = "MyApp"
    , Icon = "@drawable/icon"
    , ConfigurationChanges = ConfigChanges.ScreenSize 
        | ConfigChanges.SmallestScreenSize 
        | ConfigChanges.ScreenLayout 
        | ConfigChanges.Orientation)]
    public class MainActivity : Xamarin.Forms.Platform.Android.FormsAppCompatActivity
    {
       ...
    }

@jennyf19 It is disappointing that you decided not to fix this very annoying issue. We are in mobile world now, desktops are past.

@dinob Thanks for your patience. We had other work going on and this just got pushed behind a little. Sorry for the wait. The fix has been included in ADAL 5.1.1, and same fix will be in the next release of MSAL (4.3.1 most likely). Thanks for reporting this.

@jennyf19 Thank you so much for looking into this. I finally was able to resolve this stubborn issue on Android.

What I had to do: 1. Update ADAL from 3.19.8 to 5.2.0 2. Then modified AuthorityURL passed to AuthenticationContext c-tor from something like https://login.microsoftonline.com/my-tenant-id/oauth2/authorize to https://login.microsoftonline.com/my-tenant-id

After this, I was able to authenticate just like before but rotation on Android would not loose already provided user id and/or password.
