Abstract

The project Indore Business directory was based on android application. The system defines

the growing needs of the Businessmen in Indore city. Indore is the largest city and the

commercial capital of the Indian state of Madhya Pradesh. Indore city has a population of

2,167,447. Indore is often referred as the commercial capital of Madhya Pradesh with a bulk

of its trade coming from Small, Mid and Large scale manufacturing & service industries.

These industries range from Automobile to Pharmaceutical and from Software to Retail and

from Textile trading to Real estate, what not.Several IT services companies have presence inIndore. So there obviously arises a need to communicate to do business, perform commercial

practices and all these needs the information like contact number and address which was

earlier searched through typical YELLOW PAGES.

In growing Business environment, businessman needs to deal with the other businessman,

search for the shop, place like hotel, coffee shop, college, institutions, industries, firms, food

shops, restaurant etc. and want to get contact information and search in the conventional

yellow pages (a thick hard copy like diary that contains information of business organization

and commercial entities in tabular format) which contains only phone number and address,

not much information. The yellow pages are hard to carry and hard to search for when it

comes to the need to go to a place or arrangement of a particular meeting.

Even if he will go for an option like internet a no of web pages will be opened. Nobody

carries heavy gadgets like laptop now-a-days and if carries then too it is not feasible to search

anything about it.

If the Business is dynamic like packers and movers, they often needs a guide to help them

in getting the information of the place where they have to deliver the goods and commodities,

or from where they have to carry away the consignments. They may be sometimes but not

always are familiar with the place they are going to visit.

Introduction

2.1Objective

The objective is to make an android product for the Businessmen to help them

exploring their business by providing them with the facility of instant contacting with

any organization. Today every businessman has an android phone. By downloading

the application, they will be able to use the facilities provided by it. The main

objective is to make a user friendly interface of an android application, so as to benefit

the businessmen and making it suitable to call and contact to any shopkeeper

instantly, without wasting their time.

Switching from yellow pages to a ready-made mobile app.

In todays scenario, if a person has to search for a place like hotel, coffee shop,

college etc. And wants to get appropriate information will search in yellow pages

which contains only limited information hence it is wastage of time.

To switch from net surfing for a small purpose into a time saving environment.

To provide 24*7 facility for searching a place just with the help of a cell phone

means Nobody carries heavy gadgets like laptop, all the time and if carries then too itis not feasible to search anything about it.

To help the tourist with this app so that they will not require to hire the guide for the

place they are going to visit.

For taking immediate action like in case of emergency i.e heart attack, immediate

action will be needed for going to a hospital, to make a call etc.

Employees or Job seekers often require quick response so they would not waste their

precious time in surfing over the net or visiting the location.

Headache of filling forms over the internet while visiting any website for the purpose

of searching can easily be removed; hence no need to worry about the accessibility or

leak of our personal information.

2.2 Scope

In future dynamic business directory can be made, in which a user can also make

changes.

Business directory with updatable database can be made in which a businessman can

add a new business of his own or any other business or place like hotel, petrol pump,

boutique, his favorite pizza shop etc.

Also if user wants, he can delete the place which is of no use for him.

This project is only limited to Indore city, but in future it can also be made for 2 to 3

cities or the whole state.

A share option can be provided below every organization name, so that the user can

share the contact information with anyone.

If a similar web application exists i.e. an online business directory then the data

(contact information of a place) can be imported from there directly on your android

phone.

2.3 Problems in existing system

Problems faced in real life situations are as follows:

In todays scenario, if a person has to search for a place like hotel, coffee shop,

college etc. And wants to get appropriate information will search in yellow pages

which contains only limited information hence it is wastage of time.

Even if he will go for an option like internet we need to open a no of web pages

which is a time consuming process.

Nobody carries heavy gadgets like laptop, all the time and if carries then too it is

not feasible to search anything about it.


4/25

Tourist often needs a guide and is not familiar with the place they are going to

visit.

In case of emergency, like a heart attack, immediate action will be needed for

going to a hospital, to make a call etc.

Job seekers often require quick response so they would not waste their precious

time.

Headache of filling forms over the internet while visiting any website for the

purpose of searching can easily be removed,hence no need to worry about the

accessibility or leak of our personal information.

It is helpful for employees they can search the information about the desired

company.So helpful in global market to share and access the organization details.

2.4 Justification to the Project

An android application will prove to be a better solution for this, by providing

following features:

Address information: Complete address.

Message: Immediate message facility.

Website link: connect you to the official website on just one click.

Exact location: Search for exact location on maps (Google maps).

Call: In case of emergency immediate call can be made.

This android application will play important role in many areas right from the

industries to local places.It is helpful for employees they can search the information about the

desired company.So helpful in global market to share and access the organization details.Job

seekers can easily search the company or college where they will be going to attend the off or


5/25

pool campus.Tourist will not require any guide for the place they are going to visit hence they

would really enjoy even more the place without wasting time in querring or searching.

System Requirement Analysis

3.1 Information Gathering (Literature Review)

3.1.1 System Components Identified

ACTIVITY:

a. Activity is an individual user interface screen in an Android application where visual

elements called Views (also known as widgets) can be placed and the user can perform

various actions by interacting with it.

b. The widgets in an Activity can be created in two different ways, by pure java code and

by adding XML code to define the UI. The latter is always preferred.


6/25

c. An application can have more than one Activity and each Activity operates

independently, but can be linked to one another and each Activity created must be defined in

the applications manifest file.

SERVICE:

a. A service is an Android application component that runs in background and has no

visual UI.

b. Services are used to perform the processing parts of the application in the background.

a. While the user is working on the foreground UI, services can be used to handle the

processes that need to be done in the background.

A service can be started by other Android application components such as an activity or

other services and it will continue to run in the background

CONTENT PROVIDER:

a. Content provider in Android provides a flexible way to make data available across

applications. Suppose you are creating any type of data in your application.

b. Suppose a particular type of data is created in an application and they are stored at any

storage location, it may be in the data base, file system or in any online storage space.

c. Then through content providers other applications are able to query, access or even

modify the data been created, as long as the content provider allows it.

d. In a similar way one can access the data that other utilities have created, by using

content providers.

BROADCAST RECEIVER:

a. Broadcast receivers are one of Android application components that are used to receive

messages that are broadcasted by the Android system or other Android applications.

b. There are many broadcasts that are initiated by the Android system itself and other

applications can receive by using Broadcast receiver.

INTENTS:

a. Intents are not one of Android application components; instead it is the component

activating mechanism in Android.

b. It constitutes the core message system in Android and defines a message to activate aparticular component.


7/25

c. For example, if a new activity is to be invoked from a current activity, intent needs to

be fired specifying the new Activity. And if other application needs to be started from the

Activity, then also it would require to fire intent.

3.1.2 System Architecture for Proposed System

System Structure:


9/25

Methodological contributions:

In this project various methods for implementing Google maps, phone dialer, sms service etc.

will be required as the major features. Here are few methods which will be used mainly.

Methods and resources for Google maps:

Geopoint-to set the location of any particular point.

setZoom-to zoom in or zoom out in the map.

locationManager- which provides APIs to determine location and bearing of the

underlying device (if available).

animateTo- To animate properties for a View , call animate() to construct a

ViewPropertyAnimator object for that View .

MAP API KEY-used to programetically access data from google server.

Methods for Dialer:

launchDialer- The method launchDialer(String) initiates the phone call.

Various permissions are also used for these services like-

Geolocation permission

Internet Permission

call_phone Permission


10/25

write_External_storage Permission ,etc.

Packages used-

Location and map based capabilities incorporated into the mobile for users are done using the

package android.location and Google Maps External Library.

1. android.location-

The central component of the former package is LocationManager system service which is a

class.This class provides access to the system location services which in turn allow

applications to obtain periodic updates of the device's geographical location.

You do not instantiate this class directly;instead, retrieve it through

getSystemService(Context.LOCATION_SERVICE).

Once the LocationManager is instantiated,application is able to-

1. Query for all the LocationProvider for the last known user location.

2. Register/Unregister periodic updates of the user's current location from a location

provider.

LocationProvider is an abstract superclass that provides the periodic updates of the

geographic location of device.

Classes and interfaces in the android.locationpackage are-

1. Interfaces-

GpsStatus.Listener Used for receiving notifications when GPS

status has changed.

GpsStatus.NmeaListener Used for receiving NMEA sentences from the

GPS.

LocationListener Used for receiving notifications from the

LocationManager when the location has

changed.

2. Classes-

Address A class representing an Address, i.e, a set of

Strings describing a location.

Criteria A class indicating the application criteria for


11/25

selecting a location provider.

Geocoder A class for handling geocoding and reverse

geocoding.

GpsSatellite This class represents the current state of a GPS

satellite.

GpsStatus This class represents the current state of the

GPS engine.

Location A class representing a geographic location

sensed at a particular time (a "fix").

LocationManager This class provides access to the systemlocation services.

LocationProvider An abstract superclass for location providers.

GpsStatus.NmeaListener-

NMEA 0183 is a standard for with marine electronic devices and is common method for

receiving data from GPS .

Geocoder-A class for handling geocoding and reverse geocoding. Geocoding is the process of

transforming a street address or other description of a location into a (latitude, longitude)

coordinate. Reverse geocoding is the process of transforming a (latitude, longitude)

coordinate into a (partial) address.

Location-

A class representing a geographic location at a particular time. A location consists of latitude,

longitude, UTC timestamp & information on altitude,speed & bearing.

2. Google Maps Android API-External Library

To make it easier for you to add powerful mapping capabilities to your application, Google

provides a Maps external library that includes the com.google.android.maps package. The

classes of the package offer built-in downloading, rendering, and caching of Maps tiles, as

well as a variety of display options and controls.

The key class in the Maps package is com.google.android.maps.MapView, a subclass of

ViewGroup.


12/25

A MapView displays a map with data obtained from the Google Maps service. When the

MapView has focus, it will capture key presses and touch gestures to pan and zoom the map

automatically, including handling network requests for additional maps tiles. It also provides

all of the UI elements necessary for users to control the map. Your application can also use

MapView class methods to control the MapView programmatically and draw a number of

Overlay types on top of the map.

Challenges in determining User Locations-

When developing a location aware application for android, GPS and Androids Network

Location Provider can be utilized to get the location of device.Since GPS is most accurate but

only works outside, consumes more battery power and does not responds as quickly as

expected.

Androids Network Location Provider determines user location using cell tower and Wi-Fi

signals, providing location information in a way that works indoors and outdoors, responds

faster, and uses less battery power.

Obtaining user location from a mobile device can be complicated. There are several reasons

why a location reading (regardless of the source) can contain errors and be inaccurate. Some

sources of error in the user location include:

Multitude of location sources

GPS, Cell-ID, and Wi-Fi can each provide a clue to users location. Determining

which to use and trust is a matter of trade-offs in accuracy, speed, and battery-

efficiency.

User movement

Because the user location changes, you must account for movement by re-estimating

user location every so often.

Varying accuracy

Location estimates coming from each location source are not consistent in their

accuracy. A location obtained 10 seconds ago from one source might be more

accurate than the newest location from another or same source.

3.2 System Feasibility

After the analysis and specifications of the requirements of the proposed system feasibility

study is conducted. It is done to find out whether the system is beneficial to the organization


13/25

or not. For each proposed solution it is checked whether it is practical to implement that

solution, this is done through feasibility study. Various feasibility aspects are considered .

The feasibility study includes the investigation of the information needs of the end user and

objectives, constraints, basic resource requirement and cost benefits. The main and prime

objective of feasibility study is not to solve the problem but to acquire a sense of its scope.

The feasibility study includes the investigation of,

Needs of the end user and objectives

Information

Constraints

Basic resource requirements

3.2.1 Economical

The system is economically feasible because there are no requirements of any special Costly

hardware or software to develop the system. This system uses minimum resources for

development and usage so it is very economic and user friendly system. The organization for

which it is meant can avail it at a very low cost. The objectives are fulfilled within minimum

resources.Hence our project is economically feasible.

3.2.2 TechnicalThe project is technically feasible because it will not develop or use any technology which is

under research. The project uses Android and java as front end and designing is done using

Eclipse IDE. The back end of the project is SQLite which is again a part of android itself.

In technical feasibility the following issues are taken into consideration:

1. Whether the required technology is available or not?

The work for the project can be done wih the current equipment and existing software

technology that the organisation possessess.

2. Whether the required resources are available?

The system does not have any rigid hard-ware and software requirements and there is

availability of the people who can perform the software engineering activities required for the

development of the system.Hence, the system is technically feasible.

3.2.3 Behavioral


14/25

Behavioral feasibility is concerned with as curtaining the views of the examiners and

organizers about the use of the computer facility. The support or the lack of the support that

the examiners are likely to give to the system is the critical aspect of the feasibility in all

respects except the behavioral and fails miserably because of human problems. Our project is

behavioral feasible because it is time saving and reliable.

For which problem do you lack good solutions?

There was need to create a integrated system which surpasses the expectations of the person

needing the information regarding pvc pipes manufacturing company and through which

Administrators can also update & access the information from any location all over the

world.

How would you like to solve it?

To solve this problem we have made a web based application through which customer that

can do online Registration on the site and without extra effort can get the all the basic

information about company.Admin module is also made web based and hence administrators

can access from any where in the world.

3.3 Platform specification (Both Development and Deployment)

3.3.1 Hardware

Architecture: Android application architecture follows very modern Model-View-View

Model (MVVM) architectural pattern in how it handles relationships between GUI and a

logic supporting the GUI. This is actually good news for Android developers since this is the

latest and greatest architecture for GUI applications at the moment. In MVVM architecture:

GUI development is done by a GUI designer in technology more or less natural

for this task (XML)

Logic behind the GUI is implemented by a developer as ViewModel (which

actually means Model of View) component.


15/25

Functional relationships between GUI and ViewModel are implemented through

bindings that essentially define rules like if a button A is clicked, method

onButtonAClick() should be called on ViewModel. Bindings can be written in the

code or defined in a declarative way (Android uses both types of bindings)MVVM architecture is used in one way or another by all modern GUI

technologies like Microsoft WPF and Silverlight, Oracle (former Sun) JavaFX,

Adobe Flex, AJAX.

Backend: SQLite

Frontend: SDK

Server: apache-tomcat-7.0.23

HardDisk: 29 MB.

3.3.2 Software implementation language/technology

Programming language: core java

Querry Language: SQL

Operating System: Windows XP professional

Framework: eclipse helios
