Suppose i've enrolled 5 fingerprints in my phone. I need to check which of the 5 fingerprint is used for login to my application. Or any way to check the fingerprint if it's not the primary fingerprint.

Currently this behaviour is not available in fingerprint API as for the API it's just authentication data and receive authenticated result from Android device..
