BiometricPrompt Executor and/or callback was null
问题 I'm using BiometricPrompt from androidx.biometric:biometric:1.0.0-beta02 for the authenticate process. But i face very strange problem. First time i call biometricsPromt.authenticate() everything works fine, the library shows me the screen depending what security method is set(pattern,fingerprint, password and etc…) then the callback is called and everything is good. The problem is when i call biometricsPromt.authenticate() for the second time i got the error: E/DeviceCredentialHandler:
