I tried to download the examples for to book to check this. I did pull this package name from the online API documentation so I’m not sure why this build is complaining. I’ve searched on line and there are some issues with the latest tools package but I’ve yet to install this tools package so that’s not the issue.
Did you import the solutions using “Import existing Android code into workspace”, or did you use “Existing projects into workspace”? “Existing projects” should work correctly, but “existing android code” might cause problems.
