Android In Kotlin: Error In Databinding From The Project By Google Codelabs

I was doing this course offered by Google, https://codelabs.developers.google.com/codelabs/kotlin-android-training-data-binding-basics/index.html?index=..%2F..android-kotlin-fundam

Solution 1:

I got this answer by a trial method. We need to simply, Clean the project followed by Rebuilding. For this to be done, we can simply omit(or delete) the imports which are depicted in grey (i.e. they are unnecessary in the project). Then, Build->Clean Project and after that Build->Rebuild Project.

Solution 2:

Including the answer of @Chandramauli Chakraborty I also think you might have another error in your code or somewhere in any Kotlin or XML file. PLease make sure you have correctly fixed all of them,and them try to do what the college says.
