I realize this probably happened during course of writing the article - you started out with a project structure with a certain name but in packaging the tutorial for starter / final projects things may have changed. In the point of the tutorial where you first have the reader do stuff in Android Studio, you say:
Right click on MajesticReader in Project explorer and select New ▸ Module or select File ▸ New ▸ New Module
This is incorrect in relation to the project the reader actually downloads, and the screenshots are also incorrect.
The only folder named majestic reader is too far down on the hierarchy. Comparing to the final project, the place they should be creating the new module is at the project root.
