R file is missing?

Question

R file is missing in android. I had tried many solutions like clean project, rebuild project, sync Gradle but couldn't fix it.

are you able to run the app? Iam asking because, sometimes android studio simply complains but actually the app can be executed — Sagar, Jun 09 '18 at 12:09
when you have a successful build, you have R in your project. also check package names — Arash Hatami, Jun 09 '18 at 12:09

Android Studio won't build R file because of errors in one/many resource files, for instance unclosed tags. Check the xml files you modified last — randomuser, Jun 09 '18 at 12:28

Check for all your XML files for any errors. Once error is resolved, try clean and then rebuild the project.

Slide out the Build Variants Tab and make sure you are on the expected build variant. If you are missing layout files in a certain build variant, then Android Studio will fail to build and the generated R class is unavailable.

Firstly we should try to have internet while we are coding because IDE has to load many resources at this time. Secondly In that specific case I was loading a resource of type (v24). Third Resource name was in capital latter. Thats why it wasn't working properly.
