I grabbed a fresh copy of the eclipse ADT bundle today and now when I make a new app project the R folder fails to generate (As well as anything else in the gen folder. I also am unable to download API level 18 (Android 4.3).

Did anyone else run into this and if so how did you fix it / or is it something in regards to the switch from eclipse to android studio?

  • Did you check the error logs for problems? Sometimes when there are errors in the project, the files wont get generated. You can try to fix it by doing a "clean project", if that doesnt help, try clean project and restart the IDE. – bgse Sep 12 '13 at 21:19

Check first

properties > Android if any android version is checked If ok

Then properties > Java Build Path check for added dependencies have correct path (Most probably not applied in your case)

If every thing is Ok then Resart Eclipse

Reconfigure your SDK path

Window >> Preferences > Android browse SDK directory

When I upgraded to Android ADT rev 22 I got to check Android Private Libraries in the tab Order & Export of the Java Build Path configuration screen. But I suppose it only apply if you depend on libraries. See this question for details.
