Strange case where R file is not generated

Question

I have faced case where R file not generated automatically. However, this time is quite weird.

I have checked under res folder, there is no wrong in naming convention and there is no error under that folder.

I build the project min 9 and targetSDKVersion 21, and build target 21 too and I have updated Eclipse and also Android SDK Tools. What else do I need to check? I can't find the cause of error at all.

Wow your first name is IntelliJ :D Btw I can't switch it since this is my company project. — Rendy, Jan 22 '16 at 07:02
Deleting the build folders manually, clean and rebuild doesn't worked? — Sreehari, Jan 22 '16 at 07:06
@Rendy the error is encouraging you to try Android Studio listen to it dude ;) — silentsudo, Jan 22 '16 at 07:10
any wrong resource? It just needs a little mistake for example in Your xml layouts and then the R file will not be generated..... — Opiatefuchs, Jan 22 '16 at 07:14
What makes me confused is, my other colleague can compile and run the code, while i am not. I also want to switch to AS, as my own projects always runs in AS without this frustating problem. — Rendy, Jan 22 '16 at 07:18

if the problem is R file not recognized in class, then manually import R file => import [dot]R => then clean/refresh build — kishorepatel, Jan 22 '16 at 07:54
@Rendy switch to different workspace and import same project then check. — learner, Jan 22 '16 at 07:59

I have faced such problems many times.

Try below ways and you may be lucky to fix your issue:

Change the API Level to some other API Level. Then Apply. Again revert back to original API Level. By Right Click on the Project -> Properties -> Android.

or

Clean the Project.

or

Restart Eclipse.

Hope it will get fixed and Enjoy Coding.

Check that all your reference library are in the same workspace folder.
Clean and Refresh project at least 3 times :).
If nothing works, recreate the entire workspace...creating new workspace and import your project to this new workspace or delete .metadata folder of your workspace and restart Eclipse, import your projects again.

I hope it helps

Well finally I get rid of it after 6 hours. I downloaded new release of Eclipse (Mars), re-clone my project, install ADT on new Eclipse and it works now. Previously I used Luna release 2.
