Implement simple application for backup and restore a list of contacts. All the requirements from the Architecture Specification must be applied (see document bellow).
Two projects must be implemented “Android Library Project” for the Model, “Android Application Project” for the simple GUI. Simple GUI (see picture bellow) is not for production usage, just to exemine the functionality.
Backup is saved to a local folder of the external storage of a device. It must be single archive file located in a nested folder as specified in Architectural Specification.
Current task is the first part, then there will be more work.
