I upgraded Android Studio today to 3.1, and now Android Studio says it cannot resolve symbols for most of the resources (for example
?attr/actionBarSize). This doesn't seem to prevent me from building or running in an emulator so far, but these errors are making me nervous.
Has anyone else experienced this issue? How can I go about resolving it? I have tried syncing gradle and cleaning my project but it doesn't seem to help at all.
I'm using Android Studio 3.1 with Gradle version 4.4 and Gradle Plugin 3.1.0
