how to register Fingerprint for Authentication on Nexus emulator

Question

Answer 1

Open Security Settings on your Fingerprint Emulation enabled Emulator. According to Android Developers Documentation, Register 1 or 2 fingerprints with command

adb -e emu finger touch 1

or

adb -e emu finger touch 2

and save the settings. Next time when you are prompted for the Fingerprint Authentication again enter the same command

adb -e emu finger touch 1

to successfully authenticate. I just tried and it works fine.
