CHAPTER ONE
1.1. Introduction
A mobile device, which is also referred to as a handheld device or handheld computer, is a
pint-sized computing device. Mobile devices usually come with a touch or non-touch display
screen and sometimes, even a mini keyboard. There are many types of mobile devices; the
commonest ones are mobile phones, smart phones, PDAs, pagers and Personal Navigation
Devices. PDAs and smart phones are among the most preferred mobile devices, which offer
all the conveniences of a personal computer, along with a very small form factor.
Although mobile phones have taken over our current society, they have been around for
several decades in some form or another. Beginning in the late 1940s, the technology that
would later be used in today’s cell phones was created and the idea of a mobile phone was
introduced. This cell technology was first used in mobile rigs which were mainly used in
taxis, police cars and other emergency vehicles and situations. Truckers also used a form of
this technology to communicate with each other. The first mobile phones, referred to as First
Generation or 1G, were introduced to the public market in 1983 by the Motorola Company.
These first mobile phones used analog technology which was much less reliable than the
digital technology we use today. The analog phones also had a great deal more static and
noise interference than we are accustomed to today. The main purpose of this First
Generation technology was for voice traffic, but consumers felt insecure about people
listening in on their conversations. During the 1990s, great improvements were made in the
mobile phone technology. These phones used Second Generation, or 2G technology. In 1990,
the first cell phone call was made using the new digital technology that became characteristic
of this era. The Second Generation cellular phone technology was faster and much quieter
than its analog predecessor. As a result, it became even more popular than previous models,
too. The new technology also made them capable of being smaller rather than the large
briefcase-sized units from the 1980s.The Third Generation technology, or 3G, is what many
people currently use in their digital cellular phones today. This technology was created very
soon after the excitement that the 2G technology created. This new technology is not only
capable of transferring voice data (such as a phone call), but it is also able to transfer other
types of data, including emails, information and instant messages. There are currently plans

2
in place to develop a Fourth Generation – 4G – technology. Goals for this new set of
standards include a combination of technologies that will make information transfer and
internet capabilities faster and more affordable for cellular phones.
A mobile application (or mobile app) is a software application designed to run on smart
phone, tablet computer and other mobile devices. They are usually available through
application distribution platforms, which are typically operated by the owner of the mobile
operating system. A mobile operating system (OS) is software that allows smart phones,
tablet Pcs and other devices to run applications and programs. A mobile OS typically starts
up when a device powers on, presenting a screen with icons or tiles that present information
and provide application access. Mobile operating systems also manage cellular and wireless
network connectivity, as well as phone access. Examples of mobile device operating systems
include Apple iOS, Google Android, BlackBerry OS, Nokia’s Symbian, Hewlett-Packard’s
webOS (formerly Palm OS) and Microsoft’s Windows Phone OS. Android is one of the most
popular Linux based mobile operating system.[1]
1.2. Background
The mobile phone device is a very important communication tool as it was built to enhance
social contacts and network while enhancing business productivity. The mobile phone
enables us to be on time during appointments. It also helps in verifying the degree of
temperature to enable us chose appropriate dress code for the day. It keeps us informed on
current events because of its connectivity to the internet. It relaxes it also when we play
games with it or listen to music through it. The mobile device can provide the information
about something and also it detecting the location of the user.
Today, a mobile application plays a great role in our day to day activities. Tour Gondar
application is a city guide mobile application which is run in the smart phones. This
application provides basic information about the services which reside Gondar town like
Hotels, Restaurants, Attraction places, Banks, Tour and Travel agents and Health centers.
The application informs the current events in the town and also it detects the current location
of the users.

3
1.3. Statement of the problem
Gondar is one of the oldest and historical town in Ethiopian history. In this town there are
money Attraction and Historical places, Hotels ,Restaurants, Banks, Health centers and Tour
and Travel agents and also many events are happen in this town like the great epiphany
ceremony (carnival). But the people which are living in this town and also the visitors cannot
access the information about the service providers and events easily. More specific problem
listed as follows:
 User cannot access well organized information at anywhere about service provider
like Hotels, Restaurants, Attraction and Historical places ,Banks, Health centers and
Tour and Travel Agents.
 User cannot get information about service provider for 24/7 hours.
 When there is a new event(like carnival ceremony) happen in the town the user must
be wait until announced and post in mass media.
 There is no a mechanism a visitor to detect the current location.
 Manually system needs more human power and time.
1.4. Objective of the project
The general and specific objectives of the study are described below.
1.4.1 .General objective
The general objective of this project is to developing a city guide android mobile
application.
1.4.2 .Specific objective
In order to achieve the general objective of this project, the following specific objectives are
addressed.
 The system provide information about service provider either in Amharic or English
language
 The system detect the current location of the user,
 The system provide new update information about events like celebrity;

4
 The system also provides a city map to user to search a point of interests like
Attractions places, Hotels and Restaurants.
1.5. Scope of the project
Tour Gondar mobile application is software application which is run only in smartphones and
performs the following activities:
 The application gives information about the types of service which is provided by
service provider.
 The application provides a working day, time and location of service providers.
 The application provides new updated information about service providers and
events.
But the application does not include the following activities:
 The application doesn’t provide any information about services provider which is
located outside of Gondar town.
 Tour Gondar application is not operates other language rather than Amharic and
English languages.
1.6. System Development Methodology
Since the entire project requirements are not well known in detail initially, the development
team chooses prototype system development methodology to develop the new system. The
basic idea of prototype model is that a prototype build, test, and then rework as necessary
until an acceptable prototype is finally achieved from which the complete system or product
can now be developed. It is an iterative, trial-and-error process that takes place between the
developers and the users. The most significant advantage of using prototype system
development methodology is listed as follows:
 Users are actively involved in the development.
 Errors can be detects much earlier.
 Quicker user feedback is available leading to better solutions.
 Missing functionality can be identifying easily.
 Confusing or difficult functions can be identifying.

5
 Since in this methodology a working model of the system is provided, the users get a
better understanding of the system being developed.[2]
1.6.1. Investigation (fact-finding) methods
For gathering information to our project we use different methods.
 Observation: Observation is one of the most important methodologies to gathering
information by physical going to the place and looks how the current system. It can
be very difficult for humans to explain what they do or to even describe accurately
how they achieve a task, so observation very crucial to gathering information.
 Interview: Interview is another important methodology to gathering information by
asking someone a set of questions. It helps us to get critical and important
information about the overall view of the current system.
 Document analysis: This is also another information gathering methodology by
referring the document of the existing system.
1.6.2. System Development Tools
1.6.2.1. Hardware
The system needs different materials to develop the mobile application and to run the system
in the real world, the basic hardware are:
 Personal computer(PC)
 Android platform mobile
 Flash disc
 Digital camera
1.6.2.2. Software
We use the following tools to develop the mobile application:
 Eclipse (IDE)
 MySQL
 Apache

6
 Edraw-max
 Adobe Photoshop
 Microsoft Word
1.7. Significance of the project
At the end of this project, the application will raise the following significance for the users
and the town.
 The user can access organized information about services at anywhere and at any
time.
 The users (visitors) can easily detecting the current location.
 The user can find the services in a simple user interface.
 When we develop the mobile application there is some significant role in developing
technology by making the society more interact with technology, this leads to the
Gondar town to shift one step in technology.
1.8. Beneficiaries
The most beneficiaries are:
 User: when the users use this mobile application it saves their time and money.
 Town: it will enhance the development of the town in the side of technology.

CHAPTER TWO
2. Requirement Analysis
2.1. Introduction
Requirements analysis, also called requirements engineering, is the process of determining
user expectations for a new or modified product. These features, called requirements, must be
quantifiable, relevant and detailed. In software engineering, such requirements are often
called functional specification.
Requirements analysis is critical to the success of a systems or software project. The purpose
of Requirements Analysis is to obtain a thorough and detailed understanding of the user
needs and to break it down into discrete requirements, which are then clearly define, review
and agree upon with the Customer Decision-Makers. Requirements Analysis provides the
foundation for the desired product or services. [4]
2.2. Current System
2.2.1. Major function of current system
The major functions of the system that are currently available in Gondar town are providing
information manually about the service providers like Hotels, Restaurants, Tour and Travel
agent, Banks and Health centers. Other function of the current system is providing
information about events manually. Bazars, pamphlet papers and mass media are using to
advertising the town. Generally the current system uses a manually system.
2.2.2. Problem of existing system
As we have observed the existing system it is not preferable for the user since everything is
manually. As mention above the current system providing information about the service
providers and events but it is not attractive for the users and it needs more human power to
perform the activity. And also the way of advertising the town cannot address many people.
The major problems which are found in the existing g system listed as follow as:
 Availability: The current system which is existed in Gondar town is not available at
anywhere and at any time. The system does not easily providing information about

9
the service providers to the user when the user is located outside of Gondar town and
also the system doesn’t work for 24/7 hours.
 Performance: The other problem which is resided in the current system is
performance. We are measuring the performance of the current system in terms time.
The time took by the current system to proving information about the service
provider to user so slow.
 Data Storage mechanism: The data storage mechanism which is used by the existing
system is manually. The current system used more stationary materials like papers
and pen frequently to store data. Because of this the current system spent more cost
for data storage mechanism.
 Efficiency: The other crucial problem which is found in the existing system is
efficiency. We are measuring the efficiency of the current system in terms of
resource: human and time resources. The existing system needs more human power
and time to perform the task like advertising, announcing new information and store
data.
 Security: Since the current system used manually system it is easily expose to
security problem. The existing system used hard copy document to store data and it
may be stole the information by unauthorized user easily and it cause a serious
problem.
2.3. Gathering Information
Different fact finding techniques were used to gathering information about the current
system. It is the fundamental activity for the development of the system. Without them data
modeling cannot be constructed. In order to know how the existing system work and what
problem are there we have been using the following fact-finding techniques.
 Interviewing
 Observations
 Document analysis

10
2.3.1 Requirement Gathering Methodologies
To develop the new system we have to collect information, to collect information we use
different methodologies.
 Observation: The development team visiting and take look how the manual system
works.
 Interview: The development team interviewed administrator of Gondar town about
how the user gain information about the service provider which available in the
town, what is working time and days of the current system , what kind services are
provided by the current system ,what kind services are not provided by the current
system and also ask the challenge which is found in the current system and we
interviewed manager of tourism office about the general working system of tourism
in Gondar town and also we interviewed some people about how much the current
system is effective.
 Document analysis: The development team also referring the document of the
existing system.
2.3.2. Result Found
After interviewing, observing and analyzing of the current system, the development team
found some results those are listed as below:
 The current system provide information about service providers manually,
 The current system works from Monday to Friday for 7 hours in each day,
 The current system provide information about attraction and historical places
manually and
 The current system needs more time and human power.
2.4. Proposed System
2.4.1. Overview
We would like to create a mobile city guide application. Users of this application will be able
to search services, historical places and other points of interest by using two type of interface:
either a categorized list or by viewing a map. Users can also see more details of a point of
interest when they select it, like a describing text.

11
2.4.2 Functional Requirement
It is a function or features that must be include in the new system to satisfy the user needs
and also be acceptable to the user and solve the problem in the current system.
The functionality of this system are:
 The system must provide the working time, days and location of the service
providers.
 The system must provide a searching mechanism to the user to find information about
service providers.
 The system must providing information in either Amharic or English.
 The system must provide new updated information about service provider and events.
 The system must provide a map view to users to find the points of interest.
2.4.3. Non-Functional Requirement
It deals with the performance, time, cost and so on. It also describes the importance that is
not directly related to the system.
The non-functionalities of the system are:
 The user can access the information about the service provider with a second.
 Easy user interface to communication with the user.
 The user can access more relevant and reliable information.
 The user can access information at anywhere for 24/7 hours.
2.4.3.1. User interface and Human Factors
When conceptualizing the mobile applications user interface, there are a few things that you
should keep in mind. Some of the basic things such as clarity of interface, consistency from
one view to the next, and making sure that size and uniformity user interface element .
The user interface of mobile application must be easy for the user to use without any
ambiguity. Tour Gondar city guide mobile application having attractive list view, consistent
user interface and few and uniform buttons. Even if the interface is easy to use the customers,
there will be some difficulties in understanding some part of the system like how to use and

12
accessing the system. So the user must have some level of experience to accesses and use the
system easily and effectively such as:
 The user must have knowledge about how to use the smart phone
2.4.3.2. Documentation
Tour Gondar city guide mobile application provided two documentation which helps to the
user help menu and technical documentation .The help menu providing information to the
user how to use the application. The system might need to be maintained and modified in the
future therefore the maintainers will be provided with technical documentation which are the
analysis, design and implementation documents.
2.4.3.3. Hardware consideration
Tour Gondar City Guide application is deploy in Android 4.2.2 and late versions because
this are the latest’s version for android mobile phone and most people having this versions in
their mobile phone.
Version: Android 4.2.2 versions
Processor: 1GHZ
Memory: at least 512RAM
2.4.3.4. Performance characteristics
The user to access information about the service provider from server it takes only a second.
Since the information is accessed from the database, the new system can support one
thousand users at time and the user can use the system efficiently.
2.4.3.5. Error Handling and Extreme conditions
When the user make an error or extreme condition like that is not allowed by the system, the
system handle error or extreme condition by giving or show an error message and also alert
message to user.
The extreme condition that may occur in this system is:
 Out of range(when the user out of Gondar city),the system doesn’t detect the current
location of the user

13
2.4.3.6. Quality Issues
The new system is reliable, robust compare with the current system and also when we
observe the current system it’s not always available anywhere and anytime as the new
system.
Availability: The new system providing service to the client without concerning the locations
of the user and also it works for 24 hours.
Reliability: The user of the new system can access more relevant and reliable information
about the services and also it detect the current location accurately.
Robustness: The ability of error detecting of the new system more efficient than current
system. Since new system is based on client server architecture when error occurred we just
concerning manly on server side. For this reason we are saving time to detecting error.
Content Richness: The new system providing rich information about Hotels, Restaurants,
Attraction and historical places and events in the town.
In case of our new system user involvement in the development processes is vital
requirement for the quality of the system.
2.4.3.7. System Modifications
In the future the system can be modified in order to have the following extra features that are
not implementing now.
This can be listed as:
 Enabling the users to detect the current locations using Wi-Fi rather than GPS.
 Enabling the users to viewing offline map rather than online map.
Those new features can be implemented by another programmer or by the team in future.
2.4.3.8. Physical Environment
The System is deploy in each individual smart phone. In order to detect the current location
of the user the system need protection from external factors like those things that does not
make clear line between the device and the sky since the GPS system need a clear line
between the phone and Satellites to detect the location of the user.

14
2.4.3.9. Security Issues
To protect the application from unauthorized user and malicious attack, we will concern the
security issues into two perspectives: from client and server perspective.
Client perspective
Compared with personal computers or servers, mobile devices store much more sensitive
personal information and are thus attractive targets for attackers seeking financial gain.
Because these devices are always online and have a restricted user interface, it is easier for
attackers to hide their malicious activities. This special issue aims to present high-quality
articles describing security algorithms, protocols, policies, and frameworks for applications
running on modern mobile platforms such as Android, iOS, and Windows Mobile. Security is
a major part of any Android device. Since the system will be hosted on the user smart phone
the user will provide security tools such as antivirus to protect the applications.
Server perspective
An electronic announcement board where authorized users can publish and/or read
announcements. There two types of user, author user and read-only user. The rights of a user
are determined by its type: An author user has the right to create new announcements and to
modify or delete announcements authored by himself. A read-only user has the right to read
all announcements. The announcements are centrally stored in a database server and the
author users and read-only users, can use mobile devices to perform their application related
operations remotely. The core of the application is built on mobile database technology. So
by giving such kind of privilege to the user, we can protect the data in database server from
unauthorized user.
2.4.3.10. Resource Issues
The system has a resource that requires the following performance characteristics:
 The smart phone must have enough memory space to process the application.
 The smart phone must have high processor speed.
 The phone must have a latest version of android OS.

15
2.5. System Model
A system model is the conceptual model that describes and represents a system. A system
comprises multiple views such as planning, requirement analysis, design, implementation,
deployment, structure, behavior, input data, and output data views. A system model is
required to describe and represent all these multipleviews.
System modeling is intended to assist in developing and maintaining large systems with
emphasis on the Construction phase. The idea is to encapsulate complex or changeable
aspects of a design inside separate components with well-defined interfaces indicating how
each component interacts with its environment. Complete systems are then developed by
composing these components. System modeling can increase reliability and reduce
development cost by making it easier to build systems, to reuse previous built components
within new systems, to change systems to suit changing requirements such as functional
enhancement and platform changes, and to understand systems. In this way, a system model
can satisfy different requirements such as documenting the system, providing a notation for
tools such as consistency checkers and can also be used in the design stage of system
development.[2]
Thus, system modeling is used to ensure that a developing piece of software evolves in a
consistent manner and that the task of integrating software components is simplified.

Use case diagram is a visual depiction of the different scenarios of the interaction between
actor and use case. An actor is an idealization of an external person, process, things that
interact with the system or subsystem. A use case is logical description of the slice of the
system functionality.[3]

2.5.4.2. Class Modeling
The purpose of the class diagram is to model the static view of an application. The class
diagrams are the only diagrams which can be directly mapped with object oriented languages
and thus widely used at the time of construction.[3]

Sequence Diagram
A sequence diagram is an interaction diagram that shows how processes operate with one
another and in what order. It is a construct of a Message Sequence Chart. A sequence
diagram shows object interactions arranged in time sequence. It depicts the objects and
classes involved in the scenario and the sequence of messages exchanged between the objects
needed to carry out the functionality of the scenario. Sequence diagrams are typically
associated with use case realizations in the Logical View of the system under development.
Sequence diagrams are sometimes called event diagrams, event scenarios
A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects
that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in
the order in which they occur. This allows the specification of simple runtime scenarios in a
graphical manner.[3]

CHAPTER THREE
3. System Design
3.1. Introduction
Systems design is the process of defining the architecture, components, modules, interfaces,
and data for a system to satisfy specified requirements. The System Design Document
describes the system requirements, operating environment, system and subsystem
architecture, files and database design, input formats, output layouts, human-machine
interfaces, detailed design, processing logic, and external interfaces.
In this chapter we try to discuss the design part and also we see the architecture part. After
this has been done, the analysis was completed using different UML diagram. System design
is the first step to get into the solution domain. In this document we will try to describe the
design aspect of the new system.[2]
3.2. Current software architecture
In the city currently there is no any software in use to guide the city for the users.
3.3. Proposed software architecture
3.3.1. Overview
We try show the bird’s eye view of the new system so that, the software architecture for each
subsystem functionality will be the following.

43
Figure 16 Overview of the new system
3.3.2. Subsystem decomposition
Component diagram is a special kind of diagram in UML. It does not describe the
functionality of the system but it describes the components used to make those
functionalities.
So from that point component diagrams are used to visualize the physical components in a
system. Component diagrams can also be described as a static implementation view of a
system. Static implementation represents the organization of the components at a particular
moment.
Use component diagram to partition a system into subcomponents. The main subsystem of
the system list as follows:
 User Interface subsystem
 Database subsystem
 Account Management subsystem.[3]

44
Figure 17 Components diagram for subsystem decomposition

45
3.3.3. Hardware/Software mapping
Deployment diagrams are used for describing the hardware components where software
components are deployed.[3]
Figure 18 Deployment diagram for hardware/software mapping

46
3.3.4. Persistent data management
Persistence modeling is used to communicate the design of the database, usually to the
developers. It is also used to describe the persistence data aspect of the system.

3.3.5. Access control and security
In this new system different actor have access to different functionality and data. Who can
access what is by using an access control matrix is describe in the following table. The
following table describes an actor who is involved in the scene and the possible benefit
assigned to the actor.
Actor Privilege
User requestToView();
Administrator uploadData();
updataData();
deleteData();
Table 16 Access control and security

50
3.3.6. Subsystem services
In this section try to cover the main subsystems that are used in the system and the service
provide by each subsystem. Those are:
 User interface subsystem: this subsystem used to interact the user with system and it
is majorly connected with the database subsystem for displaying up to date
information that is stored in database.
 Database subsystem: this subsystem is used to perform the task that is performed by the
administrator. The tasks that are performed in the database are updating information such as
deleting and uploading information.
 Account management subsystem: this subsystem is used to perform user management
and validating there account.

3.3.8. Package
Package diagram is UML structure diagram which shows packages and dependencies
between the packages. Package diagram enables you to gain a high level understanding of the
collaboration among model elements through analyzing the relationships among their parent
package. This also helps explain the system's architecture from a broad view.[3]

CHAPTER FOUR
4. Implementation
4.1. Mapping models to code
The system has the following actors.
 Administrator
 User
The administrator who controls all over the system and access the tables in the database these
are:
Administrator
Figure 22 Mapping model for administrator
Notice: The administrator has permission of managing or controlling the application and it
has one to one relationship.
Events
Hotels
Restaurants
Attractions
Banks
Health Centers

54
The users can view and access information from the database.
