Biometrics – AndroidX
Android has supported fingerprint sensors since API 23 and previously we looked at the new APIs to handle them using BiometricPrompt and BiometricManager. For the latter we looked at how to create a compat wrapper so that this works back to API 23. But we didn’t implement one for BiometricPrompt. Since writing those articles, I…

Kotlin: Function References
Kotlin is a very feature rich language with and the subtleties of some of these features are worthy of some exploration to fully appreciate. In this ad-hoc series we’ll look at some of these, and in this article we’ll look at function references and some of the really nice tricks that we can achieve with…
Muselee 16: Q Connectivity – Part 3
Muselee is a demo app which allows the user to browse popular music artists. It is not intended to be a fully-featured user app, but a vehicle to explore good app architecture, how to implement current best-practice, and explore how the two often go hand in hand. Moreover it will be used to explore how…
