Android Question BiometricManager - Maven artifact not found

[LucaMs]

I tried the example attached to BiometricManager - Biometric Authentication
and got:

Installed all items suggested by SDK Manager.
Tried with Android API 30 and 29.

1. First step is to update to B4A 10.7. Using an older version is a waste of time.
2. Open B4A sdk manager and install the missing resource. Don't assume that it will be in the recommended items list.

Done. Now I get:

Generating R file. Error

It is "dangerous" (for me only) ?.

Anyway, I'm trying.

Done. Crash without logs. Unfiltered logs are useful to make you crazy!

... but I tried and maybe the "main" error message is:

Add this line and clean the project:

#AdditionalJar: androidx.arch.core:core-runtime

Does it work?

Now I got an error message with filtered logs:

Added:
AddPermission(android.permission.USE_FINGERPRINT)
and now it works, although...

in app I see a msg (a label, I think):

"Can't authenticate: NONE_ENROLLED"

(with the old version it worked - same device)

Maybe it is due to a setting on my smartphone...


P.S. No.

 

[LucaMs]

Maybe it only works with Android 11.

I remember that with the "the deprecated FingerprintManager API" (from Google documentation) it worked.

 

[LucaMs]

"Can't authenticate: NONE_ENROLLED"

What that means? Not literally, I would like to know the specific meaning related to the context.

Ok, I understand the matter; I thought that my smartphone had memorized my fingerprint and used it to unlock the screen, but no. Now it does and the app no longer gives me that message (NONE_ENROLLED); however as soon as I press the "Please authenticate" the app crashes again:
