In this tutorial, we'll be discussing and implementing the Android MVVM Architectural Pattern in our Android Application. We've previously discussed the [Android MVP Pattern](/community/tutorials/android-mvp). Why do we need these patterns? Adding everything in a Single Activity or Fragment would lead to problems in testing and refactoring the code. Hence, the use of separation of code […]
