android: data binding error: cannot find symbol class

Question

I am getting started for using DataBinding feature. I am facing problem with it.

Error:(21, 9) error: cannot find symbol class ContactL

Answer 1

In my project it was a trouble in:

android:text="@{safeUnbox(viewmodel.population)}"

So I've wrapped it in String.valueOf() :

android:text="@{String.valueOf(safeUnbox(viewmodel.population))}"

And it was resolved
