2.2 Tools and Technologies:
1. Android:
Android is a mobile operating system (OS) based on the Linux kernel and currently developed by Google. With a user interface based on direct manipulation, Android is designed primarily for touchscreen mobile devices such as smartphones and tablet computers, with specialized user interfaces for televisions (Android TV), cars (Android Auto), and wrist watches (Android Wear). The OS uses touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to manipulate on-screen objects, and a virtual keyboard. Despite being primarily designed for touchscreen input, it also has been used in game consoles, digital cameras, regular PCs (e.g. the HP Slate 21) and other electronics.
Android is popular with technology companies which require a ready-made, low-cost and customizable operating system for high-tech devices. Android's open nature has encouraged a large community of developers and enthusiasts to use the open-source code as a foundation for community-driven projects, which add new features for advanced users or bring Android to devices which were officially, released running other operating systems.
Android, Inc. was founded in Palo Alto, California in October 2003 by Andy Rubin (co-founder of Danger), Rich Miner (co-founder of Wildfire Communications, Inc.), Nick Sears (once VP at T- Mobile), and Chris White (headed design and interface development at WebTV) to develop.
Android SDK: The Android SDK provides the API libraries and developer tools necessary to build, test, and debug apps for Android.
Why Android?
A secure mobile experience: A dedicated work profile, hardware-based encryption and sharing restrictions ensure business data - calendars, contacts, files and apps - are separate and safe from malware while personal information stays private.
Easy to manage: IT has full control of all work related policies, profiles and data - from distributing apps to wiping business information - and the standard Enterprise Mobility Management (EMM) framework delivers a consistent experience across all devices.
All the apps you need: Find and deploy business apps easily with Google Play and create apps quickly with the Android app framework. Seamlessly integrate with existing IT systems like Microsoft Exchange, IBM Notes and Google Apps for Work.
A seamless experience: Switch between work and personal activities intuitively and seamlessly.
Data separation with multiple profiles: Work and personal information is securely separated and managed on a single device, with multiple profiles.
Standard APIs for EMM providers: A full range of management APIs will be available on all Android devices, ensuring a consistent user experience.
Secure app deployment: All business apps are managed and distributed to the work profile through a managed version of Google Play.
Flexibility: Internally developed enterprise apps can be self-hosted on premise or hosted by Google.

7 By – Raval Sneh
Full app management support: APIs for complete app management via EMM solutions. Whitelist apps and control installs and updates for business users.
Collaborate anyplace: Connect wherever you are with enterprise apps for mail, contacts, calendar and tasks. Full support for Microsoft Exchange, IBM Notes and Google Apps for Work.
Work anytime: Create files and edit in real-time from your smartphone or tablet using Docs, Sheets and Slides designed and optimized for mobile devices.
Browse online with confidence: Use the internet for work safely using the intuitive and secure Chrome browser, built on top of Android's security framework.
2. Eclipse:
Eclipse is an integrated development environment (IDE). It contains a base workspace and an extensible plug-in system for customizing the environment. Written mostly in Java, Eclipse can be used to develop applications. By means of various plug-ins, Eclipse may also be used to develop applications in other programming languages: Ada, ABAP, C, C++, COBOL, Fortran, Haskell, JavaScript, Lasso, Natural, Perl, PHP, Prolog, Python, R, Ruby (including Ruby on Rails framework), Scala, Clojure, Groovy, Scheme, and Erlang. It can also be used to develop packages for the software Mathematica. Development environments include the Eclipse Java development tools (JDT) for Java and Scala, Eclipse CDT for C/C++ and Eclipse PDT for PHP, among others.
3. Unity3D:
Unity is an entire ecosystem of tools and services designed for people who want to build a successful business by creating multiplatform games and interactive content. The Unity ecosystem is available to anyone who downloads the Unity engine. The Unity engine integrates into one unparalleled platform the tools to create 2D and 3D interactive content; collaboration solutions; rapid multiplatform deployment, and retention, advertising and analytics services to grow your business.
Unity is a cross-platform game creation system developed by Unity Technologies, including a game engine and integrated development environment (IDE). It is used to develop video games for web sites, desktop platforms, consoles, and mobile devices. First announced only for Mac OS, at Apple‟s Worldwide Developers Conference in 2005, it has since been extended to target more than fifteen platforms. It is now the default software development kit (SDK) for the Nintendo Wii U.
Unity is notable for its ability to target games to multiple platforms. Within a project, developers have control over delivery to mobile devices, web browsers, desktops, and consoles. Supported platforms include BlackBerry 10, Windows Phone 8, Windows, OS X, Linux (mainly Ubuntu)[citation needed], Android, iOS, Unity Web Player (including Facebook), Adobe Flash, PlayStation 3, PlayStation 4, PlayStation Vita, Xbox 360, Xbox One, Wii U, and Wii. It includes an asset server and Nvidia's PhysX physics engine. Unity Web Player is a browser plugin that is supported in Windows and OS X only. Unity is the default software development kit (SDK) for Nintendo's Wii U video game console platform, with a free copy included by Nintendo with each Wii U developer license. Unity Technologies calls this third party provisioning of a free SDK, an "industry first".

3. Process Model – Spiral Model:
The spiral model is similar to the incremental model, with more emphasis placed on risk analysis. The spiral model has four phases: Planning, Risk Analysis, Engineering and Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model). The baseline spiral, starting in the planning phase, requirements is gathered and risk is assessed. Each subsequent spiral builds on the baseline spiral.
Planning Phase: Requirements are gathered during the planning phase. Requirements like „BRS‟ that is „Bussiness Requirement Specifications‟ and „SRS‟ that is „System Requirement specifications‟.
Risk Analysis: In the risk analysis phase, a process is undertaken to identify risk and alternate solutions. A prototype is produced at the end of the risk analysis phase. If any risk is found during the risk analysis then alternate solutions are suggested and implemented.
Engineering Phase: In this phase software is developed, along with testing at the end of the phase. Hence in this phase the development and testing is done.
Evaluation phase: This phase allows the customer to evaluate the output of the project to date before the project continues to the next spiral.
Diagram of Spiral model:

Advantages of Spiral model:
 High amount of risk analysis hence, avoidance of Risk is enhanced.
 Good for large and mission-critical projects.
 Strong approval and documentation control.
 Additional Functionality can be added at a later date.
 Software is produced early in the software life cycle.
When to use Spiral model:
 When costs and risk evaluation is important
 For medium to high-risk projects
 Long-term project commitment unwise because of potential changes to economic priorities
 Users are unsure of their needs
 Requirements are complex
 New product line
 Significant changes are expected (research and exploration)
4. Analysis:
4.1 Feasibility study exciting system:
A Feasibility study is undertaken to determine the possibility or portability of either improving the existing system or developing a completely new system.
Feasibility is the measure of how beneficial or practical the development of information system will be to an organization. The feasibility study involves following criteria.
 Whether the identified user needs may be satisfied using current software and hardware technologies.
 The study will decide if the proposed system will be cost-effective and if it can be developed given existing budgetary constraints.
 The result should inform the decision of whether to go ahead with a more detailed analysis.
There are three methods of feasibility study.
1. Technical feasibility
2. Economic feasibility
3. Behavior feasibility
Technical feasibility:
It is measure of the practicality of specific technical solution and the availability of technical resources and expertise. Technical feasibility is computer oriented. The “Profile Manager”, “Flappy Bird” and “Nightmare” and is technical feasible because of the following reasons.

10 By – Raval Sneh
 In Game hardware and software requirement are easily available.
 The games have a good GUI interface.
 The games will have user friendly form and screen.
To check whether the module technically feasible or not we have to give the following two question answer.
Q-1 Is the proposed system practical?
Ans. The proposed system is definitely practical as we have all the resources available. Also building up this module requires the minimum amount of hardware & software is easily available. So, the proposed system is extremely efficient and practical.
Q-2 Do we currently possess the necessary technology?
Ans. Looking into the system requirement, we can see that we possess all the hardware and software requirements. Also the technology used is easily available and deployed all around the world.
Economic feasibility:-
It is a measure of the cost-effectiveness of a project or solution. This is often called a cost-benefit analysis. Economic feasibility deals with the cost and benefits of the information system.
In the economic feasibility, the development cost of the system is evaluated weighing it against the ultimate benefit derived from the new system. It is found that the benefit from the new system would be more than the cost and time involved in its development.
The Game is Economical feasible because of the following reasons.
Game requires less time to react for the user.
The cost of the hardware and software are normal.
GUI interface.
The system provides the services for the decision making. As this not begins a conversion of the present module into and rather begins creating a new module from scratch, the cost of the module includes cost of the module development; implementation and it not include the maintenance.
Operational Feasibility:
Operational feasibility covers two aspects. One is the technical performance aspect and other is the acceptance. Operational feasibility determines how the proposed system will fit in the current operations and what, if any job restructuring and retraining may be needed to implement the system.
In the system operational feasibility checks, whether the user who is going to use the system is able to work with the software‟s with which the system is coded and also the mind of the user going to use the system. If the user does not understand or is able to work on the system further development is of waste.
Behavioral feasibility:-
Behavior feasibility determines how much effort will go in the proposed information system and in education and training efficiency on the new system.

It is a measure of how well the solution will work in the organization. It is also a measure of how people feel about the application. Behavior feasibility is people oriented. Some question arises in the behavior feasibility, we discuss on this question.
Q-1 Is the problem worth solving or will the solution to the problem work?
Ans. Yes, the problem is off course worth solving because the system existing today is more time consuming and full of extra content like advertisement, other application link etc. so, the problem is worth solving.
Q-2 How the end-user feels about the problem?
Ans. This Game provides a best operator specification through its user friendliness. That is any kind of training is not required to play the game. So, the non-technical person can use it.
5. Profile Manager:
Profile Manager provides a way to manager profile of your Android device with future time. Profile Manager automatically set your device profile to silent or vibrate on specific time and back to the ring mode on given time.
The idea of developing this Application is come from the classroom, Many times in lecture students are forgot to silent or vibrate the cellphone and there phone are ringing in the lecture which was disturb the whole class. So I developed Profile Manager in this application you set the starting time, Profile Mode (Silent or Vibrate) and end time. When the start time arises the device switch in selected profile and when End time arise device back to the Ring mode. This all done using the AsyncTaskRunner class.
I. Input Controls:
a) Input Time using Time Picker.
b) Input Profile Mode using Radio Buttons.
c) Start Application using Button.
II. Development Workflow:
i. Design Splash Screen: Create new XML file named Splash.xml and Design Splash Screen like welcome screen of Application and put it on “ ~/res/layout/ ” folder.
ii. Create Splash Java File: Create java file to manage the Splash Screen activity like time limit to display screen, add Sound, and which activity calling next, etc.
iii. Design Main Activity Screen: Main Activity xml is the main view of game where users interacts and manage the application. I put two Textview control for display application name and current status of application, DigitalClock control to display time, TimePicker for receiving Start and End time from user, two RadioButtons for input the Profile mode and place it in RadioButtonGroup, one Button to Start Application.

iv. Create MainActivity Java File : The Actual logic of application is written in MainActivity.Java file. In this file fist I will receive input of start time when first time button is clicked and counts the difference between system time and start time like
long startmilisecond= (((timepicker2.getCurrentHour()*120)+(timepicker2.getCurrentMinute() * 60)) - ((cal.get(Calendar.HOUR_OF_DAY)*120)+(cal.get(Calendar.MINUTE)*60)+ cal.get (Calendar.SECOND) ))*1000;
Difference converts into milliseconds and call the AsyncTaskRunner class like
AsyncTaskRunner runner = new AsyncTaskRunner();
runner.execute(sleepTime); // Here sleepTime is Differences of time.
After the sleepTime thread runner will awake and called onPostExecute() method of AsyncTaskRunner class in this I will check which radio button is clicked and depend upon it set the profile mode of device using “audiomanager service” .
myAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT )// For Silent
And recall calculate the differences between start and end time and recall the AsyncTaskRunner runner thread. After completing End time reset the profile mode on ring and enable all the controls. To manage Start/End time and AsyncTaskRunner used to variables named getTime and getProfile.
v. Setting Manifest File:
In Menifest.xml file is used to give permission for resources like Internet, memory access to application and we can also set hierarchy of activity called like first Splash file called then after main activity.
vi. Create AVD :
For testing and running the application create Android Virtual Device (AVD) from window menu -> Android Virtual Device Manager. From here we can create new device or used pre-defined devices available.
vii. Run Application:
Run the application using Run Button or Ctrl+F11 key and Test the Application.
