Android Question Biometric Manager Class error

[Alberto Michelis]

Hi, using: https://www.b4x.com/android/forum/threads/biometricmanager-biometric-authentication.111256/
In a Samsing S7
I allways get a B4A example has stopped message.
Nothing in the log even compiling in debug.
Any other library to use or any thing to do?
Thanks

now Im getting

java.lang.NoSuchFieldError: No static field colorError of type I in class Landroidx/biometric/R$attr; or its superclasses (declaration of 'androidx.biometric.R$attr' appears in /data/app/b4a.example-Nwbkw1xscz3VOA24qPs-Uw==/base.apk)

Moved to the questions forum.

My guess is that you are using an old Android SDK. Follow the installation instructions: https://www.b4x.com/b4a.html

Ive made a fresh installation of b4a10.7, SDK, Java, etc.
Inatalled all of the SDK that was asked by te compilation.
Add the #BridgeLogger: true
Try it also in debug mode too
Now I can see the app opened and the Authenticate button... click it an the B4A example has stoped message appears.
An this is the error log

You make many posts and the answer to all of them is:
