Android Question Generating R File Error - Where to find more info?

Hi,

I've searched these forums (and others) looking for how to resolve this issue. But all the other threads have more information than what I'm getting. How do I see what is causing the "Generating R file" error?

There is nothing in the Logs section on the right. Are there any log files I can look at to point me in the right direction?

Thanks in advance.
