42.1 Removing the Redundant Code

Before implementing data binding within the ViewModelDemo app, the power of data binding will be demonstrated by deleting all of the code within the project that will no longer be needed by the end of this chapter.

import com.ebookfrenzy.viewmodeldemo.R

import androidx.lifecycle.Observer
