implementation 'androidx.viewpager2:viewpager2:1.0.0-beta02'
implementation 'com.google.android.material:material:1.0.0'
implementation 'androidx.vectordrawable:vectordrawable:1.0.1'
implementation 'androidx.annotation:annotation:1.1.0'

I was facing similar problem, Rebuilding the project resolved it.

Android Studio Menu -> Build -> Rebuild Project.

Thank you. I had to remove my .gradle and build folder, then click rebuild :) – Dimitri Oct 24 '19 at 11:30

The combination of these tips was the only thing that solved it for me \o/. Not even "Invalidate caches and restart" did it. – Augusto Carmo Dec 02 '19 at 12:02

First, try:

Build -> Clean Project.

It's faster than Rebuild and except once, always fixed my problems. If it doesn't work, try to rebuild it as @Rahul mentioned.

This is possibly due to build issue.

Either

remove the old build folder with ./gradlew clean inside the android directory, or
simply remove android/app/build folder
