Thanks! In my case until the warnings found in the resources were preventing the generation of automatic R.java. To fix it i setup Android Lint (Window -> Preferences -> Android -> Error Checking Lint) to mark the problems less relevant as Information instead of Warning, the damn R was created at the time!

So, what if you checked

1) the res/ dir
2) android manifest.xml

and you find nothing wrong?

Does anybody know of a list of possible error places that the ADT won't report nicely?

I have 462 "problems" reported. All are "R cannot be resolved..."

Problem solved. It was all about multiple substitutions in string resources. Frustrating, and a little scary.

I did have a bad XML file, and R.java disappeared. I have now got rid of the offending item, it still won't regenerate. Any ideas?

Thank you! This is very helpful!!

You just saved my life! I had entered an empty string in string.xml which caused the R file to stop updating... I did a clean to try and rectify the issue and it deleted R.java! Thanks!

Thanks. You're a lifesaver!

I had the same issue, however I discovered that there was a "untitled folder" inside my res/ folder, probably added it there by mistake, once removed, it was able to recreate R.java

I can't believe I'm commenting on my own post to thank myself for sharing.

A few months in, and I totally forgot how to rectify the darn issue.

Now you can imagine how satisfying it can be to find your own post that hits the nail squarely!

This time it was an error in AndroidManifest.xml.

Thanks for sharing, just saved me a few hours of frustration! I was trying to rename my package and R disappeared. Reappeared after correcting references to the old package name in the XML layouts.
