R.java未在Eclipse中生成

Question

R.java is not generated. I tried several strategies like cleaning and building etc, none of them seemed to work. Please dont mark this as duplicate since I have tried all the strategies that has been told in other questions.

Answer 1

A common problem with not generating the R file is that you have an error somewhere in your code. Something doesn't match, isn't imported, etc. The R file isn't built until your code can be compiled without errors, even though sometimes it does anyway. I can't give you a reason why it does that, but make sure you don't have errors.

Answer 2

Go to the bottom of your eclipse view and look for a tab that says "Console". It may just show you that youve declared something in one of your layouts that doesnt make sense to the compiler or something like that. Also check the error log and the problems tab.
