‘canAuthenticate()’ is deprecated in android

What should I use instead of biometricManager.canAuthenticate() is deprecated.

Doc says

This method is deprecated. Use canAuthenticate(int) instead.

    BiometricManager biometricManager = BiometricManager.from(this);
    switch (biometricManager.canAuthenticate()){
        case BiometricManager.BIOMETRIC_ERROR_HW_UNAVAILABLE:
            break;
        case BiometricManager.BIOMETRIC_ERROR_NO_HARDWARE:
            break;
        case BiometricManager.BIOMETRIC_SUCCESS:
            break;
        case BiometricManager.BIOMETRIC_ERROR_NONE_ENROLLED:
            break;
        case BiometricManager.BIOMETRIC_ERROR_UNSUPPORTED:
            break;
    }

How to use canAuthenticate(int) like the above manner.

Answer

The direct replacement for your code would look something like:

switch (canAuthenticate(Authenticators.BIOMETRIC_WEAK)) {
   case ...
}

According to the javadoc, the possible return values are BIOMETRIC_SUCCESS, BIOMETRIC_ERROR_HW_UNAVAILABLE, BIOMETRIC_ERROR_NONE_ENROLLED, BIOMETRIC_ERROR_NO_HARDWARE, or BIOMETRIC_ERROR_SECURITY_UPDATE_REQUIRED., as before.
