also probably delete this line which sometimes creeps up :
import android.R or something like that.

this is not a permanent solution, you must have to clean and build again.

yeah i did but the problem is still continuing

thank you now no error but while running time the following error is coming "An internal error occurred during: "Launching New_configuration". Path for project must have only one segment."

@ezil: Go to Run>>Run configurations... and find "New_configuration" and delete this and run again.
Are you using Eclipse? Try project -> clean
Otherwise: check your console in the bottom for errors that need fixing before your R is build

If a restart, clean and things like that do not work, you must check the errors and fix them. What errors do you have apart from the R related ones?

thank you but now while run time " 'Launching New_configuration' has encountered a problem. An internal error occurred during: "Launching New_configuration" error message is coming
I just had a reoccurence of the dreaded "R cannot be resolved" error, and I went through all the usual fixes; make sure all resources have lower case names, do a clean, make sure there isn't an import android.R lurking somewhere... no luck.
After a couple of frustrating hours I realised I had saved a PaintShop Pro format file (something.psp) in a resource folder in the file system and Eclipse was pulling it into my res folder. Not being a .png, it choked, and that seemed to cause the problem. As soon as I removed the .psp the error disappeared.
Hope this helps prevent someone else pulling out their hair.
