How to generate R.java

Question

I downloaded few source codes from Google source codes.

I executed them on Eclipse but R.java file is not created and therefore I got many errors saying

Answer 1

Cleaning the project, delete the R.java and regenerate it. If you have an error anywhere in your /res file (the resources) , the R will not be generated usually. It could be an error in the name of a picture , or anything ... fix your errors before. good luck ;)
