Android studio :: Unable to see a source folder

Question

I recently migrated my project to Android studio. I have placed all my library source folders under Application/library/src/main/java.

There is one folder named "rcs". I can see it in my windows explorer. But, I cannot see it in Android studio project view or any other views. And I can see that, wherever I refer the contents of this folder, I am seeing "Cannot resolve symbol" for this particular folder.

But I see those files are compiled and present in the "exploded-aar" folder of my application folder. Just that, they are not present in the project explorer.

Please input your suggestions. I don't have a classpath or .cvsignore or .gitignore.

Answer 1

Folder named "rcs" was ignored by Studio as its a version control system. Fixed it by changing:

Go to File > Settings > Editor > File Types > ”Ignore files and folders”.
