34.2 The Key Components of Data Binding
By default, an Android Studio project is not configured for data binding support. In fact, a number of different elements need to be combined before an app can begin making use of data binding. These involve the project build configuration, the layout XML file, data binding classes and use of the data binding expression language. While this may appear to be a little overwhelming at first, when taken separately these are actually quite simple steps which, once completed, are more than worthwhile in terms of saved coding effort. In the remainder of this chapter, each of these elements will be covered in detail. Once these basics have been covered, the next chapter will work through a detailed tutorial demonstrating these steps in practical terms.
34.2.1 The Project Build Configuration
Before a project can make use of data binding it must first be configured to make use of the Android Data Binding Library and to enable support for data binding...
