Abstract:
In today’s world time management is a big task. Now a
day, we have a trend of using smart phones supporting
different tools and applications which could make our life
simple. The proposed study is based on android devices
such as smart phones and tablets running on the Android
operating system. A location-based service (LBS) is a
mobile application that is dependent on the location of a
mobile device. A positioning component is usually needed
in a LBS application to determine the location of user's
mobile device. Most of the current LBS services do not
require users to input location manually, like giving zip
code or street name. In the proposed system we will discuss
about the application which provides the service of
automatic profile changing, weather detection, sending
message automatically by taking current location of user
in case of emergency and remainder based on the user’s
location from one to other. It uses internet connection and
GPS services to learn about the user’s current location.
Key Words: LBS, Android Operating System, GPS,
SQLite.
1. INTRODUCTION
The idea of using the mobile phones is to deliver the
valuable services. Location-based services or LBS refer to
a set of applications that exploit the knowledge of the
geographical position of a mobile device in order to
provide services based on that information. Location
based services (LBS) provide the mobile clients
personalized services according to their current location.
They also open a new area for developers, cellular service
network operators, and service providers to develop and
provide value-added services: advising clients of current
traffic conditions, providing routing information, helping
the users to find nearby shopping malls. Location-based
services offer many merits to the mobile clients. For the
mobile user, the examples of location based services are:
• Profile changer based on place or area
• Person Location tracking by Family Member
• Nearest Friends notification reminder
Location based Services can be classified in following
categories
a. Public Safety / Emergency Services-
The location of the client can be determined by
the mobile carrier hence it finds great use during
Emergency since it can be used during the
emergency/health hazard to locate the mobile clients.
b. Consumer Services-
Now days, smart phones like (Android,
Blackberry and iPhone) provide a set of location based
applications and services which helps the users to access
the multiple services based on the user location.
• Maps Navigation - The users can use the Google
Maps to get to the particular location or to trace the route
between any two locations.
• Marketing /Advertising - Many corporate
companies advertise their items based on the location of
the clients. For Example – Sale in Shopping Mall near to
your location.
• Location based Reminders - The phones can be
used to set as the reminder based on the location.
This proposal is made on the basis of “Location based
services on smart phone using Android application.” and
is been designed to be automatic using the GPS services
provided by the smart phone manufacturers and using
the internet services on the smart phone. This can be
possible because of the rapid growth of the wireless
communication systems and global location positioning
systems. We know that the Android is an open source
platform it allows anyone to try and develop application
for it and use it for the specific function on the devices
running Android. Since the mobile devices are built

having limited power and storage facility, it is ideal to
build applications for one specific purpose or one specific
work. In this proposed system we have designed an
application that will provide the automatic profile change
together with three different modules. There are other
various location based services as well that could be
implemented on the android devices.
2. LOCATION BASED SERVICES(LBS)
A location-based service (LBS) is a mobile application
that dependents on the location of mobile devices which
is an Information services accessible with mobile devices
through the mobile network and utilize the ability to
make use of the location of the mobile device.
A Location Based Service (LBS) is an information and
entertainment service, accessible with mobile devices
through the mobile network and utilizing this ability to
make use of geographical position of the mobile device.
LBS services can be used in a variety of way, such as
work, health, personal life, etc. LBS include services to
identify the location of a person or object, such as
discovering the nearest ATM or the nearest filling station,
tracking location of friend or employee. LBS services
include order tracking and vehicle tracking services.
There are two major parts-
 Obtaining the current location of the user.
 Utilize the obtained information to provide the
user a specific service.
In order to make LBS services possible, some
infrastructure elements are necessary, including mobile
devices, applications, communication network,
positioning component, and service servers Mobile
devices are tools used by users to access LBS services, to
send requests and retrieve results. Such devices can be
portable navigation devices (PNDs), Personal Data
Assistants (PDAs), laptops, mobile phones, and so on.
Application is the interface for users to access the LBS
service. Due to the restrictions of mobile devices (small
screen size, limited processor power and memory,
battery capacity), LBS applications need to be lightweight
and battery saving .Communication network refers to the
mobile network which transfers service request from
user to service provider, and requested information back
to the user. A positioning component is usually needed in
a LBS application to determine the location of user's
mobile device. Service providers maintain service servers
which offer different kinds of LBS services to users and
are responsible for processing service requests and
sending back request results. Servers calculate positions,
search for a route, or search specific information based
on user's position. Service providers usually do not store
and maintain all the information requested by users.
Instead, content providers are responsible for collecting
and storing geographic data, location-based information,
and other related data. These data will be requested and
processed by service servers and then returned to users.
Fig-1 shows the interactions among these
components, and the process of a LBS service. First, user
sends a service request using the application running on
mobile device (Step 1). The service request, with user's
current location information obtained from the
positioning component (in this example, GPS data), is
sent to service server via the mobile communication
network (Step 2). The service server requests geographic
database and other related database to get required
information (Step 3, 4). At last, the requested information
is sent back to user's mobile phone via mobile
communication network paragraphs must be indented.

3. GLOBAL POSITIONING SYSTEM
The Global Positioning System (GPS) is a space based
satellite navigation system that provides location and
time information in all weather conditions, anywhere on
or near the Earth where there is an unobstructed line of
sight to four or more GPS satellites. The system provides
critical capabilities to military, civil and commercial users
around the world. It is maintained by the United States
government and is freely accessible to anyone with a GPS
receiver. GPS is often used by civilians as a navigation
system. On the ground, any GPS receiver contains a
computer that "triangulates" its own position by getting
bearings from at least three satellites.
The result is provided in the form of a geographic
position - longitude and latitude - to, for most receivers,
within an accuracy of 10 to 100 meters. Software
applications can then use those coordinates to provide
driving or walking instructions. Getting a lock on by the
GPS receivers on the ground usually takes sometime
especially where the receiver is in a moving vehicle or in
dense urban areas. The initial time needed for a GPS lock
is usually dependent on how the GPS receiver starts. The
receiver has a general idea of which satellites to look for
because it knows its last position and the almanac data
helps identify which satellites are visible in the sky. This

takes longer than a hot start but not as long as a cold
start. The GPS receiver has to attempt to lock onto a
satellite signal from any available satellites, basically like
polling, which takes a lot longer than knowing which
satellites to look for. This GPS lock takes the longest. In an
attempt to improve lock times, cell phone manufacturers
and operators have introduced the Assisted GPS
technology, which downloads the current ephemeris for a
few days ahead via the wireless networks and helps
triangulate the general user‘s position with the cell
towers thus allowing the GPS receiver to get a faster lock
at the expense of several (kilo) bytes.
3.1 Working of GPS
Global Positioning System satellites transmit signals
to equipment on the ground. GPS receivers passively
receive satellite signals; they do not transmit. GPS
receivers require an unobstructed view of the sky, so
they are used only outdoors and they often do not
perform well within forested areas or near tall buildings.
GPS operations depend on a very accurate time reference,
which is provided by atomic clocks at the U.S. Naval
Observatory. Each GPS satellite has atomic clocks on
board.
A GPS receiver "knows" the location of the satellites,
because that information is included in satellite
transmissions. By estimating how far away a satellite is,
the receiver also "knows" it is located somewhere on the
surface of an imaginary sphere centered at the satellite. It
then determines the sizes of several spheres, one for each
satellite. The receiver is located where these spheres
intersect.
3.2 Latitude & Longitude
Latitude - Lines parallel to equator called latitude.
Longitude - Lines parallel to prime meridian called
longitude.

3.3 Android: Mobile Operating System
Android delivers a complete set of software for
mobile devices: an operating system, middleware and key
mobile applications. Android was built from the ground-
up to enable developers to create compelling mobile
applications that take full advantage of all a handset has
to offer. It was built to be truly open. Android is built on
the open Linux Kernel. Android support LBS Application
Programming Interfaces (APIs). Location service allows
finding out the device current location. The application
can request for periodic update of the device location
information. The application can also register a intent
receiver for proximity alerts like when the device is
entering and existing from an area of given longitude,
latitude and radius.
On a basic level, android is a distribution of Linux
that includes a Java Virtual Machine (JVM), with Java
being the preferred programming language for most
Android applications. The Android Software
Development Kit (SDK) includes a debugger, libraries, a
handset emulator, documentation, sample code and
tutorials. Android‘s official integrated development
environment is Eclipse using the Android Development
Tools (ADT) plug-in. SQLite database support is
integrated into the Android platform. The ADT plugin
includes an Android emulator that allows for the
simulation of GPS and Wi-Fi. The Android emulator is
depicted.
3.4 Android Location API
These are the different classes present under
Location API package to retrieve the Location
information of the user.
a. Location Manager-
The class provides access to the location service. It
also provides facility to get the best Location Provider as
per the criteria.
b. Location Provider -
It is an abstract super class for location providers. A
location provider provides periodic reports on the
geographical location of the device.
c. Location Listener -
This class provides call back methods which are
called when location gets changed.
d. Location Manager -
The class provides the application to choose suitable
Location Provider by providing access to set of required
properties of the Location Provider. Android also provide
an API to access the Google maps. So with the help of the
Google maps and the location APIs the application can
show required places to the user on the map.
3.5 SQLite
SQLite is a software library that implements a self-
contained, zero-configuration, transactional SQL

database engine. SQLite is the most widely deployed SQL
database engine in the world. The source code for SQLite
is in the public domain.
4. MODULES IN ANDROID APPLICATION
a. Profile Change Based On Location or Area
In this module of project we are going to implement
automatic profile changing facility means using this
feature of our android app, the profile of user‘s mobile
device will automatically change according to places
where person goes. The user needs to register the
particular places/location for which he wants to change
the profile. And accordingly the profile changer will work
in that particular registered perimeter only. Here first the
user‘s mobile device will locate using GPS technology
then according to place the profile of mobile will change.
Sometimes the person forgets to change the profile of
mobile phone at certain places, so this app will help
which automatically change profile.
b. Location Based Reminder
In this module of project, alerts to be display after
entering to a specified zone/area. Smart phone user can
set the remainder for any work with location. When user
can reach that location, location will be detected and then
automatically it can receive the remainder for the work
that already set by the user. In this location can be track
by using the GPS.
c. Weather Detection of Current Location
In this module of project, we can detect the
temperature of current location of the smart phone user
and display it to user.
d. Sending Emergency Message to Members
In this module of project, the emergency message is
send to specific contact member by automatically
considering the current location of user. The user does
not require to creating a messages because by default
message is already present there. At the time of sending
automatically insert the current location of the user &
message is send to members which are already present in
the contact list.
5. CONCLUSION
In today’s fast moving world people tends to reduce
their work effort and also save their time. This
application intelligently provides the services as per
locations, thus reducing human efforts. One of the best
ways to personalize information services is to enable
them to be location based. It is an excellent tool that helps
us in our daily life. We might forget to mute our phone
before entering into any important meeting and lose the
impression of the delegates sometimes. So using this
application the user can focus on his daily activities
without worrying to monitor his mobile device. It also
provides the location based reminder, sending message
in case of emergency & weather detection which is very
important in day to day life. The behavior of the model is
totally depends on internet connection or Wi-Fi
networks.
