Fingerprint authentication screen
For past 2 years, I have been working on some apps which use FingerprintManager intensively. Those apps had different UI requirements for fingerprint authentication flow and the reason was that the project owners wanted to have fingerprint authentication screen similar to their favorite apps.As you can see,
even though all of those apps are in fingerprint authentication screen, each of them has different look and feel. In my opinion, certain types of user experience should be standard on Android devices regardless of which app you use. This type of experience was missing from FingerprintManager.
