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. Page 1 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: Quiz Application Development using Android-Based Platform

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.

Page 4 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].

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.

Page 8 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.

Page 10 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 entertainmentbased 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.

Page 11 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 Quizzy and 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

Quizzy contains 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.

Page 13 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 fullfledged 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”.

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.

The number of questions to appear is in the range of 20 per sub categories. There are two labels in this screen, one is for correct answers and another is for wrong answers. If the user selects any of the wrong option, then the label captioned as “cross symbol” is incremented. Same is in the case of selecting right option the “correct symbol” is incremented. The countdown time is started as soon as the user starts the quiz. This screen (Fig. 5.9) is comprised of four buttons, namely (i) question mark, (ii) skip, (iii) reset quiz, and (iv) pause. The “Question Mark” button, when clicked, then among four of the options, two will be removed, providing user an ease with selection. The “skip” button is used to skip the question in which the user feels difficulty to answer. The next is “Reset Quiz” button, enabling the user to reset the quiz anytime. The last button is used to pause the quiz for a Page 30 of 63

time period of thirty seconds. In below figure 5.9, the answer is wrong that’s why one is incremented, which appears on the label.

Fig 5.9 Question screen

5.8.1 Function of question mark in Quizzy The function of the question mark: “?”, which appears on the left corner of the Fig. 5.9.1, is to skip the two options among four options. By skipping two options, user can easily select the appropriate option from the two remaining options.

CHAPTER NO. 6 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).

Fig. 6.1 MIT app inventor

Page 36 of 63

Fig 6.2 Google account 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.

6.2 Languages 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.

Page 37 of 63

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.

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.

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.
