people can use this app since it is user friendly and every one can easily understand. With this
app individuals not only get help in developing a good personality, but also help them in
improving their attitude (Nishiyama, 2013).
3. User interface prototypes
The web app can be designed by using HTML, CSS. But the implementation is done in Android studio.
Android Studio
Android studio is tool for creating apps on any type of android device. It consist of debugging, a
flexible construct system, world class code editing. It is an immediate developing system. This
permits you to concentrate on making single and high quality apps. Number of methods to develop
android but highly used and powerful to use is android studio (Kołek, 2013).
Android studio is developed for creating apps. That application can be used in daily life.
Android studio is developed by Google (Singh, Bhardwaj and Abdul Qadeer, 2012).
2

Android studio is the great code editor. It offer some more features. They are It supports to construct
Google cloud platform. It supports NDK and C++.It is easily modified grade-based constructing
system. It is fast and many options along with their functional capabilities. It contributes in
debugging andimprovingprogressofthecode.HowtoinstallAndroidstudioforwindows you have to
install the android studio before starting to develop the mobile application (Nale and Landge,
2016). From Android studio home page download and introduce .exe file is to personal computer.
In order to install android studio go throughout the instruction from setup wizard.
Need to direct the installer to appropriate place, if it asks for wherever java is installed.
HTML
HTML stands for Hyper Text Markup Language. This language is made for producing the
web page and data that can be visualized through the internet. For any creation using html tag is
essential. There is number of desktop applications which mix web browser control to display html.
And also for communicating directly through web applications. If you need to develop desktops like
iTunes, amazon music etc. By using java technology. And implant fast, safe, light weight web
browser that controls java script, flash, HTML5, etc (Lee and Lee, 2016).
Uncertainty you need to practice HTML for your user interface. Server/client model must be used.
Developing local server is easier. On text editor develop the HTML file. HTML file can be viewed
in browser. From there you can examine your file. And rewrite it if needed. Upload on browser
(Shen, 2012).
The HTML page construction is made of head, body, header, main and footer. It is used to develop
the construction of the web application (Jeon and KOH, 2015).
CSS
CSS stands for Cascading Style Sheet. If you required to use CSS for your user interface.
Server or client model should be used. Producing local server is easier. In CSS is colon for property
and semi colon for value (Kimetal., 2011).CSS gives the pictorial performance. That may help you
to find the basic information about the content. CSS can perform much better than other. For
animation purpose power of CSS can be used. For avoiding unwanted pictures make precise
gradients. For adjusting presence of data based on your device, media Queries developed.
JavaScript
3

JavaScript is a programming language. It is also said to be JS in short form. It delivers level
of dynamism. It is entirely differ from the classical OO/UML objects. JavaScript have their
individual technique. They have no method slot or property slot. JavaScript can give an energetic
interactivity on websites. You can create animated 2Dand 3D graphics, games, application etc. it is
compact and also flexible. At the end of the line the semi colon shows that the declaration finish. It
is case sensitive. And also java script is much hard to study. For making JavaScript program, you
should get knowledge about html and css (Sari et al., 2014).
4. App Testing
A software technique for testing exclusively approved to test the apps which are provided on
the web in that app interfaces and functionalities are tested. It is the process by which mobile
device developed applications are tested for its consistence, usability and functionality. The
testing may be manual or automated. The testing techniques can differ for mobile devices (Khan,
Ali and Saleem, 2015).
Mobile Application Testing challenges
1. The mobile application testing performance is not easy. It requires to perform on
difference of versions, software platform, network condition, Shard ware (Adsul,
2016).
2. Fast changing mobile operating system, unpredictability of simulators, several
devices, and frequent introduction on new devices makes it complex (Sa'adah et al.,
2015).
Approaches of mobile app testing on cloud
The best choice for testing the mobile application is by using cloud testing. By using
cloud based approach, we attain hybrid and native mobile application automation testing. If the
long term automation testing is carried out across the predefined device set and multi-platform,
automated testing approach on cloud is used. It is very effective. It reduce the setup time for the
test. It gives strong server configurations, testing resources, and pre-configured, licensing and
highly synchronized architecture. It reduce automated testing and Time-to-market competence. It
enhance the application quality. The amount of scalability having real time effects is one of the
4

advantages of cloud approach. While running the test, the defects able to be analyzed (Daubs and
Manzerolle, 2015).
5. Business plan
Creating a solid idea about business plan helps to thinking about application. In order to start
and implement business. Should have a great idea about business plan that may help all
information about business and its development. For analyzing, worksheet grow to think and it is
unique. Mission statement is important to all business. Quiz application is an android app.

Quiz app is mostly designed for high schooling students who wants effective type of
learning. Quiz app is the realistic learning material. It help students to save time and keep
interested on learning. It will acts as smart learning technique. Instead of using study guide,
paper back study guides. And also books are huge and uninteresting. Quiz app is totally useful in
learning (Dutta and Vandermeer, 2017).
Quiz app may help high school students, colleagues, etc. it can be very useful to learn more
and more about general knowledge and their basic materials of their educations. It is studying
and preparation tool. It may also help to reach the success in school. Similar quiz app have
realized by some other companies. It can be installed in computer as well as mobile. It can act as
finest educational apps for students. It help students to get success in their exam.
6. Marketing

this app and this makes the user to use this at any time. Many users can use this app together
with relaxing mind and without stress. The quiz app is user friendly and thus makes the user to
use it in an easier way (Hensel, 2015)
7. Research
The thousands of quiz apps are accessible for low cost or free. The application permits the
user to track activity, share progress on social media, set goal and collect ideas about their daily
activity. The examination suggest that the application basis in behavior change technique,
evidence based practices and health behavior theory are lacking. It makes difficult to examine
the health behavior variant techniques on mobile technologies. In few quiz applications, behavior
change methods are used. The costly applications manage to be greater quality which in term of
usability and involve few behavior change methods. The long life of application usefulness on
the changes of behavior is unpredictable (KOCAKOYUN, 2017) .

The physical activity literature review related applications on smartphone able be effective in
advancing enhance in mental strength for short period of time. The long term examination is
requires to examine the lifestyle changes. The customized feedback to motivate and coach also
viewed as significant. The users who utilized an application to train for quiz event enhanced self-
esteem, knowledge and feeling good among others (Oliveira and Galembeck, 2015).
It is an android app gives new methods of playing quiz by using mobile. The app is mainly
developed for the people who likes to play quiz. It gives the challenge to players. It allows the
player to play quiz by connecting Wi-Fi in android phone.
From cloud database, the questions are loaded. At the end of the game, it displays scores
such as number of skipped questions, number of correct answers and total number of question s
in the game. The major objectives of this application is to encourage the participants to play the
quiz. The application is downloaded by the users and play the games. It provides effective
challenge to the users (Moorkens, O'Brien and Vreeke, 2016).
The smartphone plays a significant role in our society for entertainment, communication etc.
like mobile computing. The innovations play an important role in teaching. It focus on teaching
the development technology to the people. It is based on software which is prototype to enhance
the participation of the students in learning. Mobile game comprises of 2 modes namely single
player and multiplayer mode consist of 3 levels having embedded scoring mechanism. The
additional features in the developed prototype is the smiley and other symbols for
communication. It was create by using java platform, java ME while the web app is developed
by ICE faces that is integrated Ajax app framework to create RIA. Research found that greater
interactivity over the users and becoming energetic in learning task (Lee, 2015).
Parse
It is the data management system based on cloud which permits the users to develop the
mobile and web applications. It is the popular backend like service platforms. The usage
provides 3 products namely parse push, parse analytics and parse core in one package. The parse
core usually maintains the social media integration and data savings. For sending push
notification, parse push is used. The parse push permit the developer to schedule, send push
notification and customize to selected set of users or registered users. The parse analytics permits
7

to track the application data namely user retention, push notification, installations and active
users (VOŠTINÁR, 2017).
Before the application tag, add the permissions in manifest file.
