in my project there is 2 modules one is a library and one is app that include this library in the library i have no such error but in app moudle i am getting this error when trying to access resources from app moudle

Answer 1

the problem was with the R file he simply was to big so he pass the limit of R file size, in order to solve that i needed to increase it by putting this line in the idea.properties file idea.max.intellisense.filesize=10000
