Hi
I have an work app whitch is running on many android devices, from 5.0 to 8.1 etc.
I am aware of this thread regarding fingerprint auth (when supported) from android 6+ and up.
I want to implement fingerprint authentification, but I don't want to modify min sdk version on manifest editor to 23.
How should I do that? I just want to use fingerprint when hardware + software are supporting this feature, else remain to classic login dialog when android is prior 6.0 etc.
Is it posible? I think so, and I think I am missing something simple. Please advice me. Thank you.
PS: something like <uses-feature android: name="android.hardware.fingerprint" android: required=“false”/>

Befor I'll do that (witch involve complex gui change in my code as it is right now) I was first thinking to only ask if such thing is possible?
I left the mahifest to min sdk 14, and added permission for fingerprint. Without any call to this class I made a compile without errors so far. So this must be it right?
