Data Binding: Views

At timestamp 00:10 in the video above, the app/build.gradle` file demonstrates a now deprecated way of Databinding as:

dataBinding {
         enabled = true
}

We instead recommend using the updated way of Databinding as follows:

buildFeatures {
         dataBinding true
}

SOLUTION:

Data binding generates the Binding object at compile time for all views in the layout.
Accessing views through the Binding object is more efficient than using findViewById.
For complex view hierarchies, data binding can be a significant performance gain.
findViewById traverses the view hierarchy at runtime to find a view every time it’s called.
