Understanding the Project Tree
Once your application is created, several folders, subfolders and files are created automatically, not easy to navigate! So here are some brief explanations on the role of each one (we will return in more detail in each part using them):
The « manifest » is the place where you must declare your activities, services and suppliers.
The « java » folder contains our files where our lines of code are located.
The « res » folder is a diminutive of resources, it is here that will be found:
The « layout » or the layout of each of your windows
The « menu« , which works in the same way as the layout, except that it only contains our menu
The « values » containing the values, for example the names assigned to our menu will have to be assigned / modified in the file strings.xml
