Movie Night Planner
Assignment 1 (20 marks)
You are to implement a simple Movie Night Planner app to create and
schedule movie viewing events and invite attendees. In this first assignment,
you will implement the basic user interface for event creation (including movie
details), editing, and calendar viewing. This will be extended in Assignment 2
to provide a full application complete with persistent storage and
networking/cloud service behaviour (including a location-based alarm that will
trigger based on your distance from your current location to that of the movie
event).
At the core of the functional requirements of this application are the following
two entities:
Event: An event is a social movie viewing activity that occurs at a specific
date, time and location and has a number of attendees. It must (at a
minimum) maintain the following information:
- Id: A randomly generated combination of numbers and letters, which
uniquely identifies an event (not visible to the user).
- Title: The title of the event (e.g. “Scary Saturday!”)
- Start Date: The start date and time of an Event (e.g. April 6th, 2019,
7.30PM)
- End Date: The end date and time of an Event (must be later than start
date)
- Venue: The location of the event (e.g. “MegaDupaMultiPlex, 13
Node.js”)
- Location: A String representation of geographical latitude and longitude
of the venue (e.g. -37.805631, 144.963053), you can get this from
Google Maps web page directly (i.e. outside of your app by just copying
and pasting the data).
- Attendees: A list of individuals who are invited to this event (as picked
from the user’s contacts list .. see supplied contacts_data/).
Movie: Each event has associated details of the movie to be viewed/screened
as follows:
- Id: A randomly generated combination of numbers and letters, which
uniquely identifies a movie (not visible to the user)..
- Title: The title of the movie (e.g. “Blade Runner”) - Year: the year the movie was released (e.g. 1982)
- Poster: an image of the poster used to promote the movie.

assignment is covered under fair use i.e.

but should not be redistributed outside the educational setting.
Functional Requirements
Your application must provide the following functionalities and meet the nonfunctional
requirements stated under the “Other Requirements” section below.
- Schedule and Unschedule an Event: The application should allow the
creation of an unbounded set of events. For simplicity, you can ignore
duplicate entries or events with overlapping times (we will make sure test
data does not overlap when assessing your assignment).
- Edit Event Details: Users should be able to edit the event details as well
as add or remove attendees.
- Add/Edit Movie details for an event: This should be implemented in a
separate screen or Activity from the Event scheduling/editing described in
the previous two points.
- View Events: Users should be able to display a list of events where each
element in the list will be a synoptic view (summary) of the Event e.g.
event title, date, venue, movie title and number of attendees. The list
should be sorted according to date (user can toggle
ascending/descending order).
- View Calendar: Users should be able to view the entries in a calendar
style layout, based on either* a week or month view (you can look at the
calendar app on an Android device or emulator for ideas but are free to be
creative with your layout). IMPORTANT NOTE: You must create your
own UI using standard layouts i.e. you cannot just use a standard or third
party Calendar widget.
- Selection/Editing: In the view modes described above, i.e. when events
are shown in a list or in a Calendar, users should be able to add or edit
items via direct manipulation (e.g. long press or gesture).
* You only have to choose one or the other but if you are having fun with
layouts you are welcome to create both so that you have a total of three
different views!
Other Requirements:
- In assignment part 1 you are not expected to persist data however your
data must not be limited to the lifetime of any specific activity (i.e. must
have application scope to facilitate testing). You should read data from the
supplied events.txt and movies.txt when your app is first loaded. - Your Graphical User Interface (GUI) must support all of the functionalities
presented under “functional requirements” above.
- The preferred Target Android Version is API Level 25, however, for
students with old devices who want to target lower levels you are allowed
to do so.
- You can write your application in the single Activity per screen phone style
however you may choose to write a tablet version using Fragments.
- You should use the Model View Controller (MVC) approach to assist in
writing modular and cohesive code. In particular we will be looking for a
domain neutral model implementation which is not dependent upon
Android specific features (i.e. java.* class/package dependencies only
not android.*). Some examples of class/interface usage in your model
would be: Event(interface)<-AbstractEvent<-EventImpl and
Movie(interface)<-AbstractMovie<-MovieImpl.
- For your UI you should aim for simplicity. You will not be marked on the
aesthetics of your design (beyond common sense!) but we are looking for
clear workflows. The only constraints on the design and classes used are
those explicitly stated above, otherwise you are free to be creative
(menus, buttons, toolbars, navigation drawers etc.)
- Your implementation must make efficient use of common values (such as
Strings, Dimensions or Colors) by (re)using values from the appropriate
XML resource file. i.e. do not hardcode such values into your layout files
or your application.
- You may want to consider branding, business models, distribution
frameworks, 3rd party integration (maps, navigation, social media sites)
etc. and how these would impact on your app design although you will not
be assessed on these features (some of these will be covered in
assignment part 2).
Code Quality
Since this is an advanced programming elective you will be marked on code
quality as well as functional correctness (approximately 60/40 split of
functionality versus quality respectively). A marking rubric is available on
Canvas for further details.
In particular:
1. You should aim to provide high cohesion and low coupling.
2. You should aim for maximum encapsulation and information hiding.
3. You should rigorously avoid code duplication.
4. You should comment important sections of your code remembering
that clear and readily comprehensible code is preferable to a comment.
5. If you use lambdas you should carefully consider the impact on
coupling, cohesion and comprehensibility. In many/most cases
inheritance, polymorphism and delegation are better approaches when
used well. 6. Where appropriate, MVC controller functionality should be placed in
separate classes in a separate controller package. A good rule of
thumb is if it is more than a single method call, or there are non-local
variable dependencies, then put it in a separate class!
Submission Instructions
Your project should be implemented using Android Studio and your project
exported as a single compressed .zip archive before submission. Do not use
any other compression formats - use of other formats (e.g. tar.gz, RAR, etc.)
may lead to delays in marking and/or a deduction of assignment marks.
Important Regulations
- You are free to refer to textbooks and notes, and discuss design issues
(and associated general solutions) with your fellow students and on
Canvas; however, the assignment should be your own individual work
(or optionally a pair of students, see details below).
- Note that you will only be assessed on your own work so the use of third
party designs and APIs (beyond the standard Android libraries) is not
allowed.
Optionally forming pairs:
This assignment is of a size and scope that can be done as an individual
assignment. However, since we understand that some students benefit from
working in pairs we will allow optional pairs to be formed. We will however
strictly adhere to the following procedure, keeping in mind that group work is
NOT a core learning outcome of this course and is only offered as an
extra/bonus option.
This assignment can be done in pairs or individually. If done
individually there is no marking advantage. If done as a pair, students
are NOT marked individually, only as a pair (No ifs, no buts .. so when
choosing a partner it is Caveat Emptor i.e. Buyer Beware!).
If students choose to be a pair they must register together in their
tutelab class in week 2 with their student ids (NOTE: Student pairs are
encouraged to be in the same scheduled tutelab but this is not strictly
required other than initial signup).
If students are unable to attend together due to timetabling issues
students must promptly confirm their pairing via email to their tutor.
If you fail to inform your tutor that you are working as a pair you must
submit individually and not share any source code.
Students cannot change pairs but pairs can separate and both
students become individuals if problems arise with the pairing (both
students being able to use any shared code that has been created to
this point). In this case your tutor must be notified at the latest by
Friday 5th April 2019 (end of week 5).
No changes will be allowed after this time unless special consideration
applies. NOTE: The required implementation language for this assignment is Java
since it is stable, widely used and most importantly students can leverage
their experience from the pre-requisite courses. Moreover, Android is
challenging enough (by design) without having to learn a new language at the
same time. However, if students have a compelling reason to use Kotlin and
can demonstrate a track record of high competency and independent learning
they can make their case to their tutor in the tutelab (email applications are
not acceptable since this is a special arrangement) and your tutor may use
their discretion and make a decision to allow this.
This assignment is due at 6:00PM Thur. 18th April 2019 and is worth
20% of your final assessment
