Android Fingerprint Scanner, detecting the finger used for authentication

Question

I'm looking to detect which finger is used for device authentication in Android Marshmallow. The callback used for getting the successful authentication is -

onAuthenticationSucceeded(FingerprintManager.AuthenticationResult result)

However I don't see how can I use the FingerprintManager.AuthenticationResult object to detect the finger used for authentication.

Any help is appreciated on this.

Answer 1

There is absolutely no way to do this, or to hack your way around it. Sorry.

The underlying Fingerprint API is so secure and locked down, and it kind of has to be, as it's data that can be used to open the device and authenticate the user.

Answer 2

No, i think theres no such facility provided by android till now. so, there is no way to found detecting the finger used for authentication.
