I have updated my `SDK` and `ADT` to the latest version, I have also update the `Eclipse` to `Kepler` the latest one after `Juno`. 

My `ADT` version is `22.0`. After this update when I create a new project, I'm getting error, stating `R cannot be resolved to a variable`. I have imported `import android.R;`, but it is showing as unused import stating `Don't include android.R here; use a fully qualified name for each usage instead`. 

Same thing is happening with Mac OS also with the latest update. I have tried renaming `activity_main.xml` to other name, but still my `R.java` is not generated. 

Tried all the things which are possible. Cleaned the project, build the whole workspace. Nothing helping.

I think `ADT` or `Eclipse` compatibility is having problem after the update.

I have updated my whole SDK, here is the screenshot, but same problem is there.
