CHAPTER NO. 1
INTRODUCTION
Development of android-based Quiz application is mainly required by students and learners to
prepare themselves for different examinations directly through smart phones and tablets in
hands. One of the major goal of our project is to facilitate students in learning, gaining and
improving their knowledge skills. At the meantime, our app provides them fun so that the users
can prepare for interviews, entrance tests or any other corresponding purposes in a fresh mood
and can’t get bored or frustrated due to dullness of app. We designed the application to facilitate
the users to be able to take short quizzes using portable devices such as smart phones and tablets.
1.1 Background Context
The Expert System(ES), namely Interactive Learning Using Expert System Quizzes was proposed
by John A. Byers and Alnarp, at Sweden in 1999 [1]. He combined database of text with HTML
(Hypertext markup language) code and JavaScript to make Interactive quizzes. The compilation
of the HTML pages with appropriate JavaScript and specific text of questions & answers is
performed by an executable program (QUIZMAKE.EXE) compiled from QuickBasic code.
Questions are given along with multiple choices and at the end the accuracy of correct answers are
displayed after calculation. The above mentioned software can be downloaded at [2]. This quiz
provides users the feature of making their own quiz. The operational version of the aforementioned
system is available at [3].
The Web based expert system, by [4] is an online learning center. This is the Student Edition for
learning and preparation. It is a multiple choice quiz. After each and every question, five choices
are given. Users can select a single choice at a time. After giving answer to all of the questions,
users will submit the answers, and then a result or progress report is displayed containing total
number and accuracy of correct, incorrect and un-answered questions. Email facility is also
provided in HTML or Text format; one can email or send results to his/her own id, to instructor,
to the TA and others.

of 63
The Quiz Hub [5] is an online Interactive Learning Quiz Games, focused on facts. This quiz has
many sub categories. It provides many fields to users, students and learners for the learning
purpose. The categories are Math facts, U.S. History, Multiply fractions, Vocabulary Quiz,
Spelling Quiz Game, Physics and others. It is not a multiple choice quiz; one has to select the
matching pairs in this quiz.
The current documentation [6, 7, 8, 9, 10, 11, 12] of different studies are organized in the context
of opinion mining and lexicon based sentiment analysis related to quiz applications. However most
of such systems are either web- based or desktop-based and directs the user generated content.
There are many researches [13, 14, 15, 16, 17, 18] in the field of quiz application development
which are conducted to evaluate the growth in knowledge and skills.
1.2 Motivation
As Android is rapidly getting famous day by day and the number of its users are increasing with
every blink of eye, because it is easy to access the necessary android based applications on smart
phones and tablets in your hands. Therefore, we found this idea interesting, easy and time efficient
to facilitate the users in this way without any difficulty. There are many online quiz applications
available on internet, but most of them are only for entertainment and fun. Moreover, if one is
going to appear in any test or interview, then it is difficult and time consuming for them to read
the full books or articles related to specific fields for the preparation or revising their knowledge.
But the most attractive feature of our app is that we take learning and fun side by side. Our app
provides them the facility to revise their knowledge or to learn something advantageous at one
place without wasting their time.
1.3 Objectives
The basic objective of this project is to develop an android-based system with following features,
namely: (i) Questions bank, (ii) Time frame, (iii) Life lines, (iv) Data Storage, and (v) Multimedia
support (pictures, snapshots, tables). The main objective to create this Quiz app is to help the users
for the preparation of necessary educational purposes regarding Computer Science and IT field
with an easy access to our app directly on their Android phones. Through our app, users can learn
and prepare themselves for interviews, tests and exams on Android phones, and can also use this
app for increasing their general knowledge about Computer Science, Verbal and Analytical
everywhere and anytime.

1.4 Problem Statement
It is essentially required to assist students for the learning and preparation of different tests
conducted for admission in higher studies in Pakistan. However, there exist no such application in
android-based platform, which can provide candidates with both preparation of such tests in
user friendly and interactive way. This is what we tried to address in the development of Quizzy:

CHAPTER NO. 2
EXISTING SYSTEM
Although there are number of web-based and android based applications which are, one way or
other related to quiz, however, there are only few that help in learning and contribute to the
academic enhancement of the students. Most of the available applications are aiming at having a
fun or entertainment. Among the many applications, we review some Web based and Android
based applications that are quite famous and are successful in terms of amount of players and
downloads
2.1 Web-Based Applications
Following is the detail of some of the selected web-based systems.
2.1.1. JAGRAN Josh Computer General Knowledge Quiz
Computer General Knowledge Quiz section is a repository of Multiple Choice Question that
make you aware about evolving nature of competitive examination, this quiz is about subjects
related to computer field. It’s a general computer quiz. This quiz is useful for the preparation of
any computer field test. In this quiz app, questions are given along with four choices, and at the
end the correct choice is also given. After preparation, students can check their level of
preparation through the quiz [19]. A snapshot of this system is shown in Fig. 2.1.

of 63
Fig. 2.1 JAGRAN Josh Computer General Knowledge Quiz
2.1.2 EDUzip The Knowledge Hub
It is a Computer Science Quiz. It contains multiple choice questions and answers with
explanations and examples (Fig. 2.2). Operating System, Database Management System,
Software Engineering, Computer Networks, Digital Electronics are the sub fields present in this
quiz. These Computer Science MCQs will help users for various Interviews, competitive exams,
entrance exams, and others [20].

Fig. 2.2 EDUzip the Knowledge
2.1.3 TreeKnox Computer Quiz
TreeKnox Computer Quiz (Fig. 2.3) is a quiz system for the help and preparation of computer
science and IT students who are going to appear in any interview, tests or exams in computer
science and IT field. Questions are given along with multiple choices and at the end of each
question, a button named “Answer” is given. On clicking that button the correct answer is
highlighted at the mean time [21].

2.2 Android Based
Following is the detail of different android-based systems.
2.2.1 Quiz app-1
This quiz application (Fig. 2.4 and Fig. 2.5) is very simple and interactive. In this there are two
modes General and Aptitude, after selecting one of them it will be redirect to the Quiz interface
which will contain question with multiple answers (options) and contain three buttons “Submit”,
“Show Answer” and “Next” [22].
Fig. 2.4 Quiz App-1.

of 63
Fig. 2.5 Quiz App-1 Result
2.2.2 Quiz app-2
It is also a simple and interactive application (Fig 2.6 and Fig 2.7). It contains three modes “Easy”,
“Normal”, “Hard”, after selecting one of them it will be redirect to the Quiz interface which
contains questions with two options, True “T” and False “F”. It also show hints when user wants
but the drawback is that user can use this life line “Hint” more than one time and it will show the
answer not hint So it is useless because user can’t learn anything from it as when will user can’t
answer the question it will tap hint button over and over again.[23]

Fig. 2.6 Quiz App-2 interface 1.

of 63
Fig. 2.7 Quiz App-2 interface.
Although there are many apps that focus on the quiz, but there are limited applications with focus
on learning or improving knowledge in curriculum area. Most of the other apps are entertainment-
based with little focus on educational paradigm.
There are many limitations with the existing systems mentioned above. To overcome such
limitations, we propose user-friendly application, namely “Quizzy”, which mainly focuses on
gaining the curriculum knowledge as well as entertainment. Therefore, when one is amazed with
playing the quiz, he/she is gaining curriculum knowledge with emphasis on not only gaining good
grades but also having better understanding of the subject matter.

of 63
Another unique feature of Quizzy that is lacking in other apps is the life lines, which it provides to
user. Users can view the hints for the right answer, can skip a question and also pause the quiz app
for thirty seconds. These life lines can be provided for the particular questions or the category itself
but user can use these life lines only once.
Other features regarding Quizzyand other apps seemed to be quite similar, i.e. answering questions
with multiple choices as fast as possible, scoring as high as possible among the group, and so on.

CHAPTER NO. 3
PROPOSED SYSTEM (FRONT-END)
The fundamental idea behind our project is to make a product that would offer new aspects of
learning. We wanted to create a tool that fits into modern age, but still stays true to the concepts
of studying. During development, we worked out some guidelines for our applications game play,
given as follows.
• Playing a round in a quiz should take less than 15 minutes.
• Users should be able to play the content they want to learn more about
Quizzycontains three types of main categories that a quiz is based on, these are; Computer science,
verbal and analytical and then computer science and verbal contains different types of sub
categories. In our prototype we are focusing at computer science’s sub category Operating System
as the first.
Following is the detail of different modules of our proposed system.
3.1 Main screen
the main screen (Fig. 3.1) is the main or starting screen of our app. It has 2 buttons, “START” &
“INSTRUCTIONS”. When the user clicks the “START” button, the control goes to the next
screen, which is “TimeOrQueMode” screen. When the user clicks the “INSTRUCTIONS”
button, the control shifts to the screen named as “Instructions Description” screen.

of 63
Fig. 3.1 Main Screen (Screen-1)
3.2 Instructions Screen
The next screen is “Instructions Description screen” (Fig. 3.2), which is simply like a “guide”. It
guides the user about each n every minor to major detail about how to play this app. The full-
fledged description about each screen and their purpose is mentioned in this screen for the better
convenience and guidance of user. By clicking the “BACK” button, the control goes back to the
main screen, i.e. to the “Screen1”.

of 63
Fig. 3.2 Instructions Screen
3.3 Time mode Screen
This screen (Fig. 3.3) contains three buttons, Time, Categories and Back. If the user clicks button
“Time” then control goes to the next screen, “TIME”. If the user clicks button “Categories”, the
control shifts to “CATEGORIIES” screen. By clicking button “BACK” the control goes back to
the “Screen1”.

of 63
Fig. 3.3 Time mode Screen
3.4 Time selection screen
The “TIME” screen (Fig. 3.4) provides this facility to users to set their desired time range for
playing the quiz. But the range has a limit and users can set the desired range within that limit.
List picker is used for this purpose. There are two buttons on this screen, “Continue” and
“Back”. When the user clicks button “Continue” the control shifts to the next screen, namely
“CATEGORIIES”, and if the user wants to go back to the “TimeOrQueMode” then he/she hits
the button “Back” for it.

CHAPTER NO. 4
PROPOSED SYSTEM (BACK-END)
4.1 Tiny DB
It is a small database which can store all kind of data string, picture, audio, video etc., and it
works on key value pair, key/tag which is used to retrieve the data from tiny db and the function
which take key as parameter called getVelue(). For saving data in tiny db we require a function
called storevalue (). It takes two parameters, tag and value. It has other use functions.
4.2 Tiny DB used in QUIZZY
In our project (Fig 4.2.1, 4.2.2 and 4.2.3) tiny db is used to transfer/exchange the data between
multiple screens. For example, on screen “sub categories” we have lists of questions and we simply
put that list which is selected by user in tiny db and retrieve that quiz list at another screen which
is Question screen. Secondly, we store temporary results in tiny db and retrieve those results in
final screen called “RESULT” screen.

TOOLS AND TECHNOLOGIES
The tool we used is “app inventor”. App Inventor for Android is an open-source web application
originally provided by Google and now maintained by the Massachusetts Institute of Technology
(MIT). App Inventor is a cloud-based tool, which means you can build apps right in your web
browser. The App Inventor software or service [24] you can get there by clicking the orange
"Create Apps!" button from any page on this website. It allows newcomers to computer
programming to create software applications for the Android operating system (OS) (Fig. 6.1). It
uses a graphical interface and led by Hal Abelson and Mark Friedman. The MIT app inventor site
can easily be accessible by anyone requiring a free Google account (Fig. 6.2).

6.1 Goals
The goal of this tool is that anyone should be able tinker their smart phone and can easily develop
their own android apps. Even it promotes beginners, non-programmer to use app inventor for
creating app. It is easy to use because it eliminates the need to remember and type code. We only
to drag and drop the components and function that exist in the drawer we have to just find them.

The language used in developing Android apps is Java and a bit of XML is also used for the UI
part, but it is easy to grab on to. So if you want to start developing apps learn Java and its various
object-oriented concepts. The official language for Android development is Java. Large parts of
Android are written in Java and its APIs are designed to be called primarily from Java. It is possible
to develop C and C++ app using the Android Native Development Kit (NDK); however it isn’t
something that Google promote.
6.3 Major libraries
App inventor uses open source java libraries that are used to create programming interface it
contain different functions, events, and procedure.

6.4 App inventor software
App inventor emulator cannot be used, if this software is not installed (Fig. 6.3). We first need to
install the app inventor software for proper working of app inventor that runs on the browser.
Fig. 6.3 Dialog window for installation.
6.5 Tool description
The app inventor consists of two components the designer viewer where the user can easily make
the desire design of her/his application. The design viewer also consists of different parts such as
palette viewer, component and procedure and properties as displayed in figure 6 .4. Each part
has its own function the palette consists of user interface (button, label, textbox, list picker, slider
etc). Lay out (horizontal arrangement, vertical arrangement etc) media (player, sound, text to
speech, camera, video player) drawing and animation (canvas, image sprite etc) sensors (clock,
location sensor, barcode scanner etc) social (email, texting, phone number etc) storage (tiny DB,
tiny WEB DB). The viewer is the part where actual designing is done. Components for giving
meaningful names. Properties where we can edit and modify the properties of the selected
component.

6.6 Building blocks
Built-in block are available regardless of which components are in your project fig 6.6. In addition
to these language blocks, each component in this project has its own set of specific to its own
event, methods, and properties.

6.7 Testing of android app
To test the app we need to connect to phone or running the emulator to see how it looks like.
App inventor provide on-screen built-in emulator for the user who do not have android device to
check the application we can test the application on phone either a Wi-Fi or a USB-cable
Build apps with an Android device and Wi-Fi Connection
If you have a computer, an Android device, and a Wi-Fi connection, this is the easiest way to test
your apps. Fig .6.7

Option Two
Don’t have an android device? Use the Emulator:
Fig 6.8 Emulator testing
If you students? Have them work primarily on emulators and share a few devices.
Don’t have an Android phone or tablet handy, you can still use App Inventor. As shown in
Option Three
No Wi-Fi? Build apps with an Android device and USB Cable:
Some firewalls within schools and organizations disallow the type of Wi-Fi connection required.
If Wi-Fi doesn’t work for you, try USB. Fig. (6.9)

6.8 Getting the app on your phone
In order to install the app on the phone we first need to download the apk (android application
package) on computer. Then either through USB-cable or Bluetooth we can get this apk file on
our android device and we now can install this apk on the phone. Fig. 6.9
Fig .6.9 Scanning of code
6.9 Android application packet (apk)
Android application package (APK) is the package file format used by the Android operating
system for distribution and installation of mobile apps and middleware.
APK files are analogous to other software packages such as APPX in Microsoft Windows or Deb
packages in Debian-based operating systems like Ubuntu. To make an APK file, a program for
Android is first compiled, and then all of its parts are packaged into one file. An APK file contains
all of that program's code (such as .dex files), resources, assets, certificates, and manifest file
6.10 Software development kit (sdk)
A software development kit is a typically a set of software development tools that allows the
creation of applications for a certain software package, software framework, hardware platform,
video games console, operating system. To create application you have to download this
application you have to download this software development kit. For example, if you want to
create an android app you require an SDK with java programming.

CHAPTER NO. 7
CONCLUSION AND FUTURE WORK
7.1 Conclusion
The main purpose of our project is to develop an application that offers new aspects of learning
and improving knowledge in educational area. Most of the available apps are entertainment-based,
which mostly do not contribute to the academic enhancement of the students.
The theme of our quiz is to provide user to practice for subjective tests conducted on national level,
so in this app we focus on Computer science field. This quiz is useful for the preparation of any of
the computer-related test.
This quiz app includes three main modules, namely (i) computer science, (ii) verbal, and (iii)
analytical. The computer science and verbal modules contains various types of sub categories. This
quiz includes three functions: (i) Hint, (ii) Skip, and (iii) Pause, which are collectively named as
life lines that help users to answer questions correctly. These functions can be used only once by
a user.
When user tap/click on “Hint”, it will show hints by disabling two extra options from four options,
then user can easily select an option from the two. Skip options can be used at of user’s choice.
This function will simply skip the current question. When user wants some time to answer a
question then he/she will use this function to pause the quiz. Resultantly, time clock is stopped for
30 sec and this time is not be added in the total time.
We have learned a lot about Android based applications and also about user’s behavior. We have
found that the development process is hard and time-consuming, but it can be managed by a team
work. We hope that other developers will take advantage from our experience/from our
development.
7.2 Future work
We are planning to keep managing the project and improving it based on user feedback. Here is
our to do list for future
 We will add some more categories in our app.
 We’ll try to make it more user friendly than it is now.
 We’ll try to improve its quality.
 We’ll work on another feature in our app to add a module namely “Make Quiz” which is
helpful for teachers to make their own quiz for their students.
