Hi, i solved the issue by creating a new module for room

Hi, I solve this problem just fixing SQL query. The problem as that userId was incorrect,
@Query("SELECT * FROM User WHERE userId = :userId") the name of the row in the table was user_id. Just fixing that and everything works fine.

I had the same issue. After spending hours on this, I finally fixed the error by replacing LiveData<ArrayList<MovieFavEntity>> to LiveData<List<MovieFavEntity>> . Just check the return type and queries of the different method in the Dao.

I guess this problem is related to kapt or annotationProcessor itself not room.
When the build fails, the databinding fails to generate these files too and Android Studio throws all errors to your face.

So you might need to go to the first error in the log or temporarily change kapt to annotationProcessor and rebuild to get clear error message.

After enabling data binding
"dataBinding {
enabled = true
}"
I get
"[kapt] An exception occurred: java.lang.ExceptionInInitializerError"

It is working fine. you just need to use the latest versions of kotlin and room. I was also facing the issues earlier when I was also using dagger but after that when I switched to KOIN and used all latest versions it is working fine.

This doesn't seem to be an issue with the samples. You can file an issue against Room on the issue tracker if you're still having an issue.
