Hi @ericc0504,

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.

Damn. I had this issue with the first biometric bindings, too. But I could not reproduce it later so I thought this was fixed. Unfortunately I think this is an issue of the underlying androidx library. I'll try to investigate this asap.

Thank you. Look forward to the next release.

@smstuebe Hi, bro.. Do you have resolved this Issue?

smstuebe commented 4 years ago

@christianaldas nope. asap != now. And as I said, I'm not sure if I can fix it, because I experienced this bug also with my own androidx bindings in the first pre releases. That's why I assume, that this bug is in the native library. I found a workaround, but can't really remember what it was (something like invalidate/reload activity). And it had the side effect, that the activity reloaded.

So, this never will be fixed?

It seems that it is a problem with the Package Xamarin.AndroidX.Biometric Version 1.0.0. If I reference the Version 1.0.1 in my app the problem is not reproducable anymore.
