Hi @bastianbecker21,

I'm the friendly issue checker. Thanks for using the issue template :star2: I appreciate it very much. I'm sure, the maintainers of this repository will answer, soon.

[bastianbecker21]

Can you give me a short answer whether it's able to do or not?

[smstuebe]

@bastianbecker21 I'm on holliday ;) It will be possible in the future. There is a PR for it already ;)

[bastianbecker21]

@smsissuechecker Yes. I was able to handle it independently with this. https://blog.xamarin.com/easily-authenticate-users-with-androids-confirm-credential/ But I want to handle all of it in one great package like this one, When can you exactly look at this bug?

[smstuebe]

It is not a bug. It is just not implemented, yet. I'm working on a major update that will include this feature and will switch to the new Android P Dialog etc.

Hi When it will be implemented...?

[sandman202]

Is there an update on this? I am looking for it to fall back to PIN, if fingerprint is not available.

[Ravi5ingh]

is there any update on this? if this method doesn't work then doesn't it mean that the whole plugin is effectively redundant?

protected override void OnCreate(Bundle savedInstanceState) {

        TabLayoutResource = Resource.Layout.Tabbar;
        ToolbarResource = Resource.Layout.Toolbar;

        base.OnCreate(savedInstanceState);

        CrossFingerprint.SetCurrentActivityResolver(() => CrossCurrentActivity.Current.Activity);
        //CrossFingerprint.SetCurrentActivityResolver(() => this);

private async void FingerPrintAuthentication(object sender, EventArgs e) { try { lblAuthenticationResult.Text = "Click on the button for FingerPrint Authentication."; lblAuthenticationResult.TextColor = Color.White;

            var ScanResult = await CrossFingerprint.Current.IsAvailableAsync(true);
            if (ScanResult)
            {
                var Auth = await CrossFingerprint.Current.AuthenticateAsync("Touch your finger on sensor to login.");

var ScanResult = await CrossFingerprint.Current.IsAvailableAsync(true); returning false. There have any solution for this?

[sandman202]

Still waiting on an update. It doesn't work for Android. Haven't checked iOS. It seems a little cumbersome to have to create my own check, when this plugin is supposed to handle it.

[smstuebe]

should be fixed. with 2.1.0. Have a look at the changelog. Please give feedback.
