Suddenly (I think) AS is marking "array", as in "R.array.arrayName", as invalid!
It's marked in red and hover claims it's an unresolved reference. However, the app builds and runs so it's clearly (?) an IDE fault, presumably comparable to the multiplatform fault that doesn't recognise external libraries. This is a multiplatform project but this code is in the Android module, not the Android section of the multiplatform module.
This is Dolphin | 2021.3.1 Patch 1.
Perhaps not a problem in itself but may indicate something else wrong? Have I done anything wrong?
