R cannot be resolved to a variable error when setting background

Question

I am making an app in which I set an image as the background but when I set this image as the background the R.java file disappears and I get the "R cannot be resolve to a variable error"

EDIT:None of the usual "R cannot be resolved to a variable" solutions did not work

Any solutions?

the problem was in the name of the image it had the invalid charecter '-' — jaisonDavis, Jul 13 '12 at 04:41

This problem mostly appear due to due to build path errors, to check problems see Eclipse Menu-> Windows -? Show View-> Error Logs and Eclipse Menu-> Windows -? Show View->Problems. and According the problem listed resolve the error, and then try to compile the project.

Maybe this will work. I'm not sure.

1. Change the name of the image(in drawable directory) you are trying to use.
2. Clean the project

Also, check your imports if u are importing android.R class instead of your own R.java class

Are you importing android.R instead of your own R class?

Try clean the project or do a manual import.
