"Cannot resolve symbol R." I've searched on Stack Overflow and they said it's a bug with A Studio is this still true?

All over my Stormy Project (Android) it's been showing the cannot resolve symbol R. I've searched all over the web and most articles say it's a bug with Android Studio is this still case?

I am not sure if it's a bug, but I get it all the time. It's super annoying. I usually do a project clean, then re-build. If that doesn't work, it's usually because somewhere in the build process, it failed.

As the project builds it creates a build file and this R.java file. If it fails to build, the R.java wont get created and the references will show up everywhere.

I usually open up the error console. Then I will remove all the errors. Do a clean and build, but not all my projects (if there is more than 1) but just build the single project. That way it lists only the errors in that project while being built. It usually is an error in there that is obscure that isn't showing up in the code. I fix that and re-build and it works.

Hope this helps.
