Directories rendered as packages in Intellij Idea 13?

Question

After a rebuild of my android project i saw that the src folder and other folders(assets, libs etc) have turned into packages.(Packages in Intellij have a folder icon with a ball inside it)

Due to this, I also got errors in all files inside src folder. (for example see SearchActivity.java , 1st line).

I am new to Intellij so apologies if this sounds rudimentary.

As of 2019.2.2, it's easiest to do File > Project Structure..., double click Modules, and then under the "Sources" tab right click the folder and un-mark it as a source folder.
