When Android released version 6.0 Marshmallow (yes, a little outdated at this point), a whole slew of new developer APIs came with it. One that I’ve personally enjoyed as a consumer is fingerprint authentication.

Eventually, though, I was able to recreate the flow. This post is going to be a step by step guide to integrating your own fingerprint dialog in your Android application.
