R file is missing android

Question

Answer 1

This happened to me while adding some new resources to my project. The R file is build after every resource update.

The error in my case was incorrect file name. One of the image resources had a capital case letter in its name and that prevented the build from creating the R file. Changing the name simply worked.

I would suggest that when you add too many resources at a time, just make sure of the naming conventions for them. Its easy to miss such things.
