The new compiler incrementally creates the binding classes, which in most cases speeds up the build process. In practice, this listener includes some non-trivial logic, including listeners for one-way data binding. Most of the time, you don’t need to rename setters in Android framework classes. Interact with other apps. The Data Binding Library automatically generates the classes required to bind the views in the layout with your data objects. The namespace of the attribute isn’t considered, only the attribute name and type are used when searching for a method. Using a ViewModel component that implements Observable gives you more control over the binding adapters in your app.
