Introduction
• Short Introduction on who you are
• Things to possibly talk about:
• What your degree you are doing
• Why you are doing it
• What sort of job you are looking for
• What are your capabilities
• What are your interests (if applicable to your app’s functionality)
• Maybe include a picture of yourself?

App Overview
• Escala App is a food recording app that lets users record the history of the food that they eat. It helps the
user to track the eating by recording the quantity of carbohydrates, proteins and fats for every meal they eat
• The app was influenced by the need to have a meal tracking food that lets users to track how they eat so
that they can live a better life
• The goal of the app is to provide a platform that makes it easy for the users to track their eating habits.
• The target market of the app can be for anybody that needs to keep track of the food they eat especially
those people dealing with weight issues or people who are sick and need to keep track of what they eat
• There is need for the escala app because it provides a simple interface bundled with features that make it
easy for the user to track meals. The app also makes it easy for the user to see what they are consuming
more or less by use of graphs. There exists other food tracking apps include
• My Fitness pal
• Fatsecret
• Yazio
• My diet coach
Despite there being similar food tracking apps Escala is desirable because of its simplicity.

App [Intended] Functionality
The app will have the following functionalities;
• The app should allow the user to register and create an account in the app
• The app should allow the user to login into their account if they have already created an
account using the registration interface.
• The app should allow the user to add new meal details. This will involve recording the
fats, proteins and carbohydrates levels contained in the meal.
• The app should allow the user to view all meal details that they have added.
• The app should allow the user to share meal details that they have saved in their
account.
• The app should give the user a graph view of their saved records using a bar graph that
is easy to understand for all users.
• The app should enable the user to quit the app using a button.

School of Computing and Mathematics
Tools and Platform Used
• The platform used to develop the application is android. The application will be
developed as a native application. The reason for choosing android as the target
platform is because majority of smartphone users are android user thus this presents
a greater market compared to other platforms.
• The tools used to make the app are;
• Android Studio 3.5
• Build #AI-191.8026.42.35.5791312, built on August 9, 2019
• JRE: 1.8.0_202-release-1483-b03 amd64
• JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
• Windows 10 10.0
• For the app to store data locally, SQLite is used as the database.
• The general requirements required to run the app are;
• Recommended OS is Android 10 which is the latest release by google
• The minimum recommended OS is android 4.3 icecream sandwich.
• Any device capable of running android 4.3 will run the application
• The application requires storage device permission

School of Computing and Mathematics
Techniques and Challenges
• The development of the app involved following a divide and conquer method where I
divided the development into phases including design, coding and testing. The first
stage was designing user interfaces and then I proceeded to do the code and finally
testing the app to make sure everything works.
• The project was a learning experience as I got to learn many things related to native
android development. The lessons were mostly through the challenges I encountered
especially when writing the code. To solve the issues experienced with the code, I
relied on Google to find solutions for some of the errors I was unable to diagnose.

School of Computing and Mathematics
Improvements for the Future!
• If the development of the app was to continue, there are a few improvements that
would be recommended to improve the design and functionality of the application.
Once of the major requirements is adding cloud capability such that the user is able to
view his or her records using any device instead of restricting the storage of the
records to only the current device being used by the user.
• The interface of the app can also be improved from the simple minimalistic design to a
better design which can be achieved by following Google’s material design
• The app can be further developed to include push notifications such that the user gets
a notification if different levels exceed a level that they set.

App Architecture

School of Computing and Mathematics
App architecture
• The class diagram shown in the previous slides shows the classes that will make up
the app. The first class is the MainActivity class which the first class that is loaded
when the app is opened. All the activity classes contain the oncreate method which
displays the interface of the class which is an xml file and any actions like buttons are
coded in this section.
• The record class is the base class which represents the model of a note record. Each
variable has a getter and setter method. When a new record is created, a record
object is initialized.

School of Computing and Mathematics
Sequence diagram
The sequence diagram shows the
interaction between the user and the
application when the user open the
app and adds a record and they are
displayed using listview and a graph

School of Computing and Mathematics
[Register]
• This use case is used to register where by the user
enters their username, email, names and password
and then presses the register button. The app
verifies the details are correct and no field has been
left blank. If the registration is successful, the app
opens the login activity.

School of Computing and Mathematics
Login
The login activity is used to login for users
who have already registered. The login
activity is displayed when the user
opens the app. To login the user has to
enter the username and password and
then press the login button. If the
details are correct the app opens the
main interface.

School of Computing and Mathematics
Add Meal Activity
The add meal activity is opened by the
user from the main interface using the
bottom navigation menu. The user
enters details of the meal and they are
saved in the SQLite database and then
opens view records interface.

School of Computing and Mathematics
Graph interface
The graph interface displays the records
entered in a bar graph. This interface
is opened using the bottom navigation
menu.

School of Computing and Mathematics
View records interface
The view records interface displays all
records entered by the user using a
listview and allows the user to share
the records through email.

School of Computing and Mathematics
Demonstration
• Demonstration shows the app running with the user performing all actions in the app.
• There are two types of demonstration
• Screen grab demonstration- This is a demonstration using screen grabs where all activities and their actions are
shown using screen grabs of the app
• Video demonstration- The video demonstration of the app shows the app running on the phone while all
functionalities are performed

School of Computing and Mathematics
MainActivity demonstration
The main activity is the first activity that the user
sees when the app is opened.it contains the
login interface and a link to open the
registration interface

School of Computing and Mathematics
Registration Activity
The registration activity is opened from a
link in the login activity. It allows the
user to register and create an account.

School of Computing and Mathematics
Home Interface
This is the first interface the user sees
after successful login. The interface
displays the records added by the user
using a graph.

School of Computing and Mathematics
Add Record interface
The add meal activity is opened by the
user from the main interface using the
bottom navigation menu. The user
enters details of the meal and they are
saved in the SQLite database and then
opens view records interface.

School of Computing and Mathematics
Add Record Validation
The add record interface validates when
the user presses the add food record
button. If one of the field is blank it
displays a message

School of Computing and Mathematics
View records interface
The view records interface displays all
records entered by the user using a
listview and allows the user to share
the records through email. It has a
floating button that is used to share the
records via email.
