11,120 PointsR reference errors with 2nd activity
I'm working on the Blog Reader app in Android Studio. When I create the second activity for the web view all of my references to R generate errors. When I delete the activity all the reference s to R are fine in the remaining activity. Whats going on here? Would creating a new activity effect R references?

Courses Plus Student 1,754 PointsHi Frankie, creating a new activity doesn't affect the R class. Maybe when you reference it in the second activity the import is from android.R, not from your own activity so see what the import is, it should be your package name. R.
Otherwise please post your code, in this way is to hard to help

11,120 PointsI reference R.id and R.sting in the first activity and it works fine in that activity. When I create 2nd activity references to R.anything in both activities throw an error that says "R cannot be resolved to a value". Must be a bug in android studio then.
