The Data Binding framework was one of Google's announcements at I/O 2015, and it represents a big change in the code organization of an Android app. Some developers are skeptical about this framework but, if used in the “right way”, it’s very powerful and it allows to remove a lot of redundant boilerplate code from activities and fragments.
In this talk you will start from the Data Binding basic concepts and then will discover how to use it to improve the architecture of a typical Android application applying the Model View ViewModel pattern. Using this pattern you need to write less code to create an app that can be easily tested using JVM and instrumentation tests.
The demo project is available here.
