Answer 1

Try the below steps to resolve the issue,It worked for me:

1. Cleaning the project and then building it again.
2. Closing project and then opening it again.
3. Going to Project Properties > Java Build Path > Tick Android Version Checkbox
4. ensure no errors in XML files,Because errors in xml file Prevents the R.jave file to be created.
5. try downloading the latest version of android SDK,if available.
