It looks like android default API is not able to handle some Samsung devices.

Two years later and the problem persists. Crashlytics lists me some occurrences for a Sony Xperia X device. Any suggestions?

@Tharkius
The workaround was using the Samsung Pass SDK if the device is Samsung's. Not really sure about Xperia.

Is not it because you're not trying to create the key when the fingerprint is not available?

Hi, we are reserving this site for questions about the sample apps specifically. For more general questions about Biometrics on Android, please use StackOverflow with tag android-biometric.

Also this sample is being deprecated in favor of BiometricLoginKotlin

Heads up: this link has changed. You can now find the example at BiometricLoginKotlin

from security-samples.

To anyone facing this issue, you have to wrap any logic that needs to create/access the keystore on whether or not biometrics authentication is possible on the device.
Example:

val hasBiometricsCapability = biometricManager.canAuthenticate(BiometricManager.Authenticators.BIOMETRIC_STRONG) == BiometricManager.BIOMETRIC_SUCCESS

if(hasBiometricsCapability){
    //generate key or access key
}
