Kotlin Standard Functions Unresolved Reference Android Studio
Suddenly all of the projects in Android Studio are getting this unresolved reference for kotlin standard functions like .let
, .apply
, listOf
& mutableListOf
and also missing coroutine scope functions like .launch
Android Studio Version : 2020.3.1
Things I've tried
- Created a new project
- Deleted App build folder & library build folder
- Cleaned Project , Rebuild Project & Invalidate Caches & Restart
- Deleted .idea folder and rebuilt project
App builds and runs fine on emulator , just the IDE gives this error in every project
I have solved the problem by changing the Gradle version.
change the gradle-wrapper.properties
