I often have problems with the R file as well. Here are some things you can try:

• Delete R.java and see if it regenerates (make sure Auto build is turn on)
• Turn off auto build and manually compile the project
• Go to your hidden .android folder and delete debug_keystore, then restart Eclipse and rebuild. May need to restart the computer as well.
