Add `setDeviceCredentialAllowed` to `BiometricPrompt.Builder` #4452

Closed haavamoa closed 4 years ago

haavamoa commented 4 years ago

I can not find the setDeviceCredentialAllowed method on BiometricPrompt.Builder in order to leverage falling back to pin-code / password / pattern. In the android developer docs it says that we should use that to fall back (doc). I also see that it is deprecated and SetAllowedAuthenticators will replace it. That might be why it's not added to Xamarin.Android yet?

Hope to see this added as we need a nice fallback for our users.

It looks like setDeviceCredentialAllowed was only added in API-29, so unfortunately it's not going to be a great fallback. 😥

You will need to set your Compile using Android version: (Target Framework) to Android 10.0 (Q) and the method should be available. But you'll need to ensure you don't try to call it on earlier devices or it will crash.
