Introduction:-

Mobile devices, such as smart phones and PDAs, are playing an increasingly

important role in peoples lives. Location based services take advantage of user

location information and provides mobile users with a unique style of resource andservices. Nowadays more and more location-based applications and services

provide users about their locations information. As location proof plays a critical

role in enabling these applications, they are location-sensitive. The common theme

across all these applications is that they offer a reward or benefit to users locating

them in a certain geographical location. But users want their exact locations to be

pointed. There are many kinds of location-sensitive applications. One category is

location-based access control.

To introduce this project is our purpose is to mark the mobile phone smarter as that

we not seen in early days. To make this application user convenient so that user

can track the location of other user, parent can know the child location and user

can find the location of their mobile phone in case of mobile phone is lost.

Our aim to is to develop the android based application where the both the user has

the android application and any user of the application can know the current

location of the user when the both the user make the communication with each

other.

There are several other reasons to develop this application is, these days mobile

theft is on the rise. On a rough estimate, there are 1.2 million to 2 million handsets

lost or stolen in the country every month. Assuming that these are low-end

handsets (priced between Rs 4,500 and Rs 5,000 each) the total lost or stolen value

of mobile handsets would be around Rs 400 crore every year. a lot of money

involved. Mobile phones have now become the most important device as it doubles

up as a wallet, not to mention its conventional uses of communication. It holds a

lot of data, e-mail accounts, power point presentation files and documents, andprotecting this is as important as protecting your wallet.So developing a mobile

tracking device will be very helpful in overcoming the problems. This software

application will help us to control and track our phone if it has been lost or stolen

by somebody. If the phone is lost, the user can be assured that it would not fall into

the wrong hands. The Global Positioning System (GPS) is a space-based global
http://en.wikipedia.org/wiki/Global_navigation_satellite_systemhttp://en.wikipedia.org/wiki/Global_navigation_satellite_system


3/36

navigation satellite system (GNSS) that provideslocation and time information in

all weather, anywhere on or near the Earth, where there is an unobstructed line of

sight to four or more GPS satellites. It is maintained by the United States

government and is freely accessible by anyone with a GPS receiver with some

technical limitations which are only removed for military users.Since the phonestoday are essentially smartphones with features such as GPS ,microprocessor etc

we can make use of them to track the phone down with good accuracy.There are

lot of applications present in the market but we will be creating one which will

overcome some of the drawbacks in the mobile tracking applications already

present.

BASIC CONCEPT:

Our project aims to create an ANDROID application which will track down the

phone wherever it is. This application will be installed on the phone and will give

the exact coordinates of the phone.

When activated the cellophane will use the get coordinates/ location from a

location provider which can be a GPS.

The coordinates will be forwarded to the online web server and the location will be

displayed using a embedded Google map.

This project is based on tracking of mobile phone in various scenarios. The variousfunctionality and roles of actors are given below:-

System scope:

The system will be deployed as an application on Android which will effectively

enable the user to utilize the inbuilt gps capabilities of android phones and hencerecover the phone.

APPLICATION:

The developed software will be deployed on individual on phones and could be

used as and when the situation demands.

This application will be highly useful for people who have important data with

them on their mobile or have expensive phones. This will help in saving thousands

of money.


5/36

Statement of Problem:-

The problem of statements is as follows,

Since the previous application take long time to send the GPS location to the

server, so that the finding the current location is difficult.

According to the other application process the user of the system must login

to the system to use the application.

That give the problem to the user, because if the user want the current location or

any user want the current location of the other the that user must login to the

application to track to the location.

There is other problem in the existing the system is the application is not sending

the user current location in timely.

Other issues is if the mobile user lost the mobile phone then finding the mobile is

much more complex task since because of required the login to the system.

Since the user is changing the current location regularly the change location data

is not update properly.

Why the particular topic is chosen:-

The main purpose of the project is to track the exact current location of the mobile

user.

The reason to choose the particular topic is, because of the GPS technique is track

the exact location of the mobile phone. So that the user can find the current

location of the other users.

Another reason for this project is it can be use when the user lost the mobile phone.Since this application is not using the login and registration process this application

can directly tack the mobile location.


6/36

Important of Purpose Investigation:-

Following are the important of purpose investigation,

The purpose is not using the user login/registration process. The purpose continuously sends the user current location to the

server.

The purpose used the GPS so it tracks the location of the mobile

location.

The purpose system can be used to find the lost mobile phone.

Objective of the system:-

Finding the exact location of the current user.

Continuously sending the current location to the web server.

Not required to login to the application.

Review of the system:-

In this section we are going to discuss the various pros and cons of the above

mentioned software already present in the market and put forth our idea for

development of another more developed application.

2.1.ANTI DROID THEFT

Add extra to security to your phone if it is lost or stolen. Track its location and take

pictures on the internet through the Anti Droid Theft.


7/36

Anti Droid Theft is one of the oldest and most popular anti theft apps used to

secure your phone by using GPS tracking and other security features. It was

created by ZOBO TECHNOLOGIES .

PROS:

1.View position of phone using GPS

2.Track changes to SIM card / phone numbers

CONS:

1. Needs password protect to uninstall app or make app hidden.

2. Time duration between GPS updates is very long.

MOBILE DEFENSE

Founded in early 2007, Mobile Defense has quickly become leaders in both

personal and enterprise mobile security. Mobile Defense was founded by Stuart

Saunders and Ken Adair. Between the two of them they have over three decades of

combined software development experience and have led large mobile initiativesin banking, security, and device management. Mobile Defense was inspired by

their experience securing mobile devices for F500 executives and institutional

traders. Mobile Defense was the first security solution for Google Android devices,

originally developed as a contender in the first Google Android Developer

Challenge. Over the years our products have grown and evolved to keep pace with

rapidly changing mobile technology.

PROS:

1. Find your phone if lost or stolen from Mobile Defenses website.2. Send alerts to your phone with alarm sound and security pin.

3. Once successfully installed, the app is not detected on the phone.

CONS:


8/36

1.No remote wipe.

2.Presently working only in U.S.Work is in progress to get it in other countries.

3.When you sign up for an account theres a waitlist before the user can register

himself/herself.

4.This is a Beta version and it is expected that the service will have premiumcharges at some future date.

Deciding when to start listening for updates

You might want to start listening for location updates as soon as your application

starts, or only after users activate a certain feature. Be aware that long windows of

listening for location fixes can consume a lot of battery power, but short periodsmight not allow for sufficient accuracy.

Maintaining a current best estimate

You might expect that the most recent location fix is the most accurate. However,

because the accuracy of a location fix varies, the most recent fix is not always the

best. You should include logic for choosing location fixes based on several criteria.

The criteria also varies depending on the use-cases of the application and fieldtesting.

Here are a few steps you can take to validate the accuracy of a location fix:

Check if the location retrieved is significantly newer than the previous

estimate.

Check if the accuracy claimed by the location is better or worse than the

previous estimate.

Check which provider the new location is from and determine if you trust it

more.

Reduce the size of the window

A smaller window in which you listen for location updates means less interaction

with GPS and network location services, thus, preserving battery life. But it alsoallows for fewer locations from which to choose a best estimate.

Set the location providers to return updates less frequently

Reducing the rate at which new updates appear during the window can alsoimprove battery efficiency, but at the cost of accuracy.


11/36

Restrict a set of providers

Depending on the environment where your application is used or the desired level

of accuracy, you might choose to use only the Network Location Provider or onlyGPS, instead of both. Interacting with only one of the services reduces batteryusage at a potential cost of accuracy.


12/36

Existing System

Today mobile phone comes with the location tracking application which tracks the

mobile phone location. This application uses the GPS (Global Position System)

which is used for the location tracking.

The application uses the satellite system for the location tracking. This location

coordinate must send the server where the location point saves. But the sendingprocess is too late so the server is not update timely. This is big disadvantage of the

current system. Since because the user can change the location as needed. So theserver is not getting the accurate location of the mobile phone.

Although some application overcome this problem but such application is needed

to register the client to use the application. This creates the problem for the user

who is not login. So the server is not able to track the current location of themobile phone.

Drawback of the Existing System

Update location data is not in timely.

Some system use login/register process.

Difficult to identify the location of the mobile phone since the user changethe location frequently.


13/36

Propose System

To overcome the problem of the update location data, required to login in theapplication to track the location we implement the new concept which is,

GPS BASE LOCATION TRACKING ON ANDRIOD.This application updateslocation data and send to the server with less time limit. This application is not

required the user to register and login process. Just both the user must the androidbased application on their mobile phone system.

The propose system send the location point using the web service technique andnot using the sms based.

Application Working

The working of the application is as follows,

Every user installs the android based application on their mobile phone.

When the two users communicated with each other their current mobile

location is send to the web server.

When the any user wants the exact location of the other user the using the

android based application is it send the request to the web server and inreturn the server send the response.

16/36

Testing Technology

System testing is a critical phase implementation. Testing of the system involves

hardware devise and debugging of the computer programs and testing information

processing procedures. Testing can be done with text data, which attempts to

stimulate all possible conditions that may arise during processing. If structured

programming Methodologies have been adopted during coding the testing proceeds

from higher level to lower level of program module until the entire program is

tested as unit. The testing methods adopted during the testing of the system were

unit testing and integrated testing.

UNIT TESTING:

Unit testing focuses first on the modules, independently of one another, to locate

errors. This enables the tester to detect errors in coding and logical errors that is

contained within that module alone. Those resulting from the interaction between

modules are initially avoided.

INTEGRATION TESTING:

Integration testing is a systematic technique for constructing the program structure

while at the same time to uncover the errors associated with interfacing. The

objective is to take unit-tested module and build a program structure that has been

detected by designing. It also tests to find the discrepancies between the system


17/36

and its original objectives. Subordinate stubs are replaced one at time actual

module. Tests were conducted at each module was integrated. On completion of

each set another stub was replaced with the real module.

FUNCTIONAL TESTING:

Functional testing is a technique in which all the functionalities of the program are

tested to check whether all the functions that where proposed during the planning

phase are full filled.

This is also to check that if all the functions proposed are working properly.

This is further done in two phases:

- One before the integration to see if all the unit components work properly

-

Second to see if they still work properly after they have been integrated

to check if some functional compatibility issues arise.

PERFORMANCE TESTING:

Expected Result

The client should be able to connect to the server properly without any

problems.

The connection establishment between the mobile device and the

server should take minimal time.


18/36

The mobile device should be able receive data from the server

uninterruptedly.

Information provided by the application should be correct and as per

the users need.

Observation

Connection can be established easily provided that the server is on.

The connection with the server takes time as it uses Internet

connection.

Receiving data from the server takes time.

Information coming from the database is correct.

LOAD / STRESS TESTING :

Expected Result

Response time should be unaffected irrespective of the no of users.

The introduction of the newer clients should not make the server to

work hap hazardously.

Continuous use of the server by different clients should not result into

the server getting slowed down.

Response time should not be degraded if there is congestion in

network.


19/36

Observation

The speed of transmission was fine even when the newer clients

were getting added. The response of the server was satisfying even

with the introduction of newer client.

Theoretical analysis of the topic

Android for Mobile Application

Androidis an operating system for mobile devices such as smart phones and tablet

computers. It is developed by the Open Handset Alliance led by Google.. Google

released most of the Android code under the Apache License, a free software

license. The Android Open Source Project (AOSP) is tasked with the maintenance

and further development of Android. Android consists of a kernel based on

the Linux kernel, with middleware, libraries and APIs written

in C and application software running on an application framework which includes


20/36

Java-compatible libraries based on Apache Harmony. Android uses the Dalvik

virtual machine with just-in-time compilation to run compiled Java code. Android

has a large community of developers writing applications ("apps") that extend the

functionality of the devices. Developers write primarily in a customized version of

Java. Apps can be downloaded from third-party sites or through online stores such

as Android Market, the app store run by Google.

ASP.NET

ASP.NET is more than the next version of Active Server Pages (ASP); it is a

unified Web development platform that provides the services necessary for

developers to build enterprise-class Web applications. While ASP.NET is largely

syntax-compatible with ASP, it also provides a new programming model and

infrastructure that enables a powerful new class of applications. You can migrate

your existing ASP applications by incrementally adding ASP.NET functionality to

them.

ASP.NET is a compiled .NET Framework -based environment. You can authorapplications in any .NET Framework compatible language, including Visual Basic

and Visual C#. Additionally, the entire .NET Framework platform is available to

any ASP.NET application. Developers can easily access the benefits of the .NET

Framework, which include a fully managed, protected, and feature-rich application

execution environment, simplified development and deployment, and seamless

integration with a wide variety of languages.

IDENTIFICATION OF THE PROJECT FROM THE STUDY

FEASIBILITY STUDY :

The very first phase in any system developing life cycle is preliminary

investigation. The feasibility study is a major part of this phase. A measure of how

beneficial or practical the development of any information system would be to the

organization is the feasibility study.

The feasibility of the development software can be studied in terms of the

following aspects:

1.Operational Feasibility.

2.Technical Feasibility.

3.Economical feasibility.

4.Motivational Feasibility.

5.Legal Feasibility

OPERATIONAL FEASIBILITY :

The site will reduce the time consumed to maintain manual records and is not

tiresome and cumbersome to maintain the records. Hence operational feasibility is

assured.


22/36

TECHNICAL FEASIBILITY :

At least 166 MHz Pentium Processor or Intel compatible processor. At least 16 MB RAM.

14.4 kbps or higher modem.

A video graphics card.

A mouse or other pointing device.

At least 3 MB free hard disk space.

Microsoft Internet Explorer 4.0 or higher.

ECONOMICAL FEASIBILTY :

Once the hardware and software requirements get fulfilled, there is no need for

the user of our system to spend for any additional overhead.

For the user, the web site will be economically feasible in the following aspects:

The web site will reduce a lot of paper work. Hence the cost will be

reduced.

Our web site will reduce the time that is wasted in manual processes.

The storage and handling problems of the registers will be solved.

LEGAL FEASIBILITY :


23/36

The licensed copy of the required software is quite cheap and easy to get. So

from legal point of view the proposed system is legally feasible.

Steps Towards Implementation

System Development Life Cycle:

The System Development Life Cycle is the process of developing

information systems through investigation, analysis, design, implementation, and

maintenance. The System Development Life Cycle (SDLC) is also known as

Information Systems Development or Application Development.


24/36

Steps involved in the System Development Life Cycle :

Below are the steps involved in the System Development Life Cycle. Each phasewithin the overall cycle may be made up of several steps.

Step 1:Software Concept

The first step is to identify a need for the new system. This will include

determining whether a business problem or opportunity exists, conducting a

feasibility study to determine if the proposed solution is cost effective, and

developing a project plan.

This process may involve end users who come up with an idea for improving

their work. Ideally, the process occurs in tandem with a review of the

organization's strategic plan to ensure that IT is being used to help the organization

achieve its strategic objectives. Management may need to approve concept ideas

before any money is budgeted for its development.

Step 2:Requirements Analysis

Requirements analysis is the process of analyzing the information needs of

the end users, the organizational environment, and any system presently being

used, developing the functional requirements of a system that can meet the needs

of the users. Also, the requirements should be recorded in a document, email, user

interface storyboard, executable prototype, or some other form. The requirements


25/36

documentation should be referred to throughout the rest of the system development

process to ensure the developing project aligns with user needs and requirements.

Professionals must involve end users in this process to ensure that the new

system will function adequately and meets their needs and expectations.

Step 3:Architectural Design

After the requirements have been determined, the necessary specifications for the

hardware, software, people, and data resources, and the information products that

will satisfy the functional requirements of the proposed system

can be determined. The design will serve as a blueprint for the system and helps

detect problems before these errors or problems are built into the final system.

Professionals create the system design, but must review their work with the users

to ensure the design meets users' needs.

Step 4:Coding and Debugging

Coding and debugging is the act of creating the final system. This step is

done by software developer.

Step 5:System Testing The

system must be tested to evaluate its actual functionality in relation to expected or

intended functionality. Some other issues to consider during this stage would be

converting old data into the new system and training employees to use the new

system. End users will be key in determining whether the developed system meets

the intended requirements, and the extent to which the system is actually used.

Step 6:Maintenance


26/36

Inevitably the system will need maintenance. Software will definitely undergo

change once it is delivered to the customer. There are many reasons for the change.

Change could happen because of some unexpected input values into the system. In

addition, the changes in the system could directly affect the software operations.

The software should be developed to accommodate changes that could happen

during the post implementation period.

There are various software process models like:-

Prototyping Model

RAD Model The Spiral Model

The Waterfall Model

The Iterative Model

Of all these process models weve used the Iterative model(The Linear Sequential

Model) for the development of our project.

The Iterative model

The waterfall model derives its name due to the cascading effect from one

phase to the other as is illustrated in Figure1.1. In this model each phase well

defined starting and ending point, with identifiable deliveries to the next phase.

This model is sometimes referred to as the linear sequential model or the

software life cycle.


27/36

The model consists of six distinct stages, namely:

1. In the requirements analysisphase

(a) The problem is specified along with the desired service objectives

(goals)

(b) The constraints are identified


28/36

2. In the specification phasethe system specification is produced from the

detailed definitions of (a) and (b) above. This document should clearly define

the product function.

3. In the system and software design phase, the system specifications are

translated into a software representation. The software engineer at this stage

is concerned with:

Data structure

Software architecture

Algorithmic detail

Interface representations

The hardware requirements are also determined at this stage along with a

picture of the overall system architecture. By the end of this stage should the

software engineer should be able to identify the relationship between the

hardware, software and the associated interfaces. Any faults in the

specification should ideally not be passed down stream.

4. In the implementation and testingphase stage the designs are translated

into the software domain

Detailed documentation from the design phase can significantly

reduce the coding effort.

Testing at this stage focuses on making sure that any errors are

identified and that the software meets its required specification.

5. In the integration and system testing phase all the program units are

integrated and tested to ensure that the complete system meets the software

requirements. After this stage the software is delivered to the customer


29/36

[Deliverable The software product is delivered to the client for

acceptance testing.]

6. The maintenancephase the usually the longest stage of the software. In

this phase the software is updated to:

Meet the changing customer needs

Adapted to accommodate changes in the external environment

Correct errors and oversights previously undetected in the testing

phases

Enhancing the efficiency of the software

Observe that feed back loops allow for corrections to be incorporated into

the model. For example a problem/update in the design phase requires a revisit to

the specifications phase. When changes are made at any phase, the relevant

documentation should be updated to reflect that change.

Advantages of the Iterative Model:-

Testing is inherent to every phase of the Iterative model

It is an enforced disciplined approach

It is documentation driven, that is, documentation is produced at every

stage

Disadvantages of the Iterative Model:-


30/36

The waterfall model is the oldest and the most widely used paradigm.

However, many projects rarely follow its sequential flow. This is due to the

inherent problems associated with its rigid format. Namely:

It only incorporates iteration indirectly, thus changes may cause

considerable confusion as the project progresses.

As The client usually only has a vague idea of exactly what is

required from the software product, this IM has difficulty

accommodating the natural uncertainty that exists at the beginning of the

project.

The customer only sees a working version of the product after it has

been coded. This may result in disaster any undetected problems are

precipitated to this stage.

User Manual

About softwares:

1.Eclipse:

Development of Android Application mainly consist of following

Packages.

1.Activities:

An activityrepresents the visual representation of an Androidapplication. activitiesuse views, i.e. user interface widgets as for example

buttons andfragmentsto create the user interface and to interact with the user.

An Android application can have several activities.

2.Fragments :


31/36

Fragments are components which run in the context of an activity.

3.Views and layout manager:

Viewsare user interface widgets, e.g. buttons or text fields.

4.Device configuration specific layouts :

The user interface forActivitiesis typcally defined via XML files (layout files).

5.Content providers :

A content providerprovides a structured interface to application data.

Via content provideryour application can share data with other applications.

Android contains an SQLite database which is frequently used in conjunction with

a content provider. The SQLite database would store the data, which would be

accessed via the content provider.

6.Services:

Servicesperform tasks without providing a user interface. They can

communicate with other Android components and notify the user via the

notification framework in Android.

7.Intents:

Intentsare asynchronous messages which allow the application to request

functionality from other Android components, e.g. fromservices oractivities.

An application can call a component directly (explicit Intent) or ask the Android

system to evaluate registered components based on the intentdata (implicit

intents). For example the application could implement sharing of data via

an intentand all components which allow sharing of data would be available for


32/36

the user to select. Applications register themselves to an intentvia an intent

filter.

Intentsallow an Android application to start and to interact with components

from other Android applications.

2. Android Development Kit (SDK) :

TheAndroid Software Development Kit (SDK) contains the necessary tools to

create, compile and package Android application. Most of these tools are

command line based.

The Android SDK also provides an Android device emulator, so that Android

applications can be tested without a real Android phone. You can createAndroidvirtual devices (AVD) via the Android SDK, which run in this emulator.

The Android SDK contains theAndroid debug bridge (adb) tool which allows to

connect to an virtual or real Android device.

3. Android Development Tools :

Google provides theAndroid Development Tools (ADT) to develop Android

applications with Eclipse. ADT is a set of components (plug-ins) which extend

the Eclipse IDE with Android development capabilities.

ADT contains all required functionalities to create, compile, debug and deploy

Android applications from the Eclipse IDE. ADT also allows to create and start

AVDs.

The Android Development Tools (ADT) provides specialized editors for

resources files, e.g. layout files. These editors allow to switch between the XML

representation of the file and a richer user interface via tabs on the bottom of the

editor.

VB.Net for Administrator server

Visual Basic is a programming language that is designed especially for windows

programming. It will explain most of the tools available for implementing GUI

based programs. After introducing the basic facilities and tools provided by Visual

Basic, we apply our knowledge to implementing a small VB program. Our

program will implement a visual interface for a commonly know stack abstract

data type.

VB.NET is still the only language in VS.NET that includes background

compilation, which means that it can flag errors immediately, while you type.

VB.NET is the only .NET language that supports late binding. In the VS.NET IDE,

VB.NET provides a dropdown list at the top of the code window with all the

objects and events; the IDE does not provide this functionality for any other

language. VB.NET is also unique for providing default values for optional

parameters, and for having a collection of the controls available to the developer.

Advantages of VB.NET :

Build Robust Windows-based Applications :

With new Windows Forms, developers using Visual Basic.Net can buildWindows-based applications that leverage the rich user interface features available

in the Windows operating system. All the rapid application development (RAD)

tools that developers have come to expect from Microsoft are found in Visual

Basic .NET, including drag-and-drop design and code behind forms. In addition,


34/36

new features such as automatic control resizing eliminate the need for complex

resize code.

Resolve Deployment and Versioning Issues Seamlessly:-

Visual Basic .NET delivers the answer to all of your application setup and

maintenance problems. With Visual Basic .NET, issues with Component Object

Model (COM) registration and DLL overwrites are relics of the past. Side-by-side

versioning prevents the overwriting and corruption of existing components

and applications.
