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.

After updating to SDK Tools to rev. 22 for the first time, you may need to relaunch Android SDK Manager again and install a new item: Android SDK Build-tools. enter image description here

After installing this, clean your projects and rebuild.
