Project won't update R.java?

My main class folder was named com.test, I changed it to com.myApplication, and now when I add objects to my layout my R.java won't get updated, all objects that I had before work fine, and they are in R.java, but anything new that I c开发者_开发技巧reate won't get added to R.java Any idea how to resolve this problem?

I solved the problem. I had some errors in my layouts due to removing some images. I fixed those problem, and it generated the R.Java again
