'R cannot be resolved to a variable' - gen folder is empty

Question

I\'ve got an error:

R cannot be resolved to a variable

in line:

setContentView(R.layout.main);

but I can\'t r

Answer 1

On eclipse you have the "Problems" window. If you fix all the other problems in there other than R cannot be resolved, the "R" problem will be auto-fixed as R is not generated because most likely you have project related problems.

Hope this helps. If you don't manage to do it, put a print of what your Problems window is showing.
