21. Android applications have
common structure
Views such as lists,
grids, text boxes, An Activity Manager that
buttons, and even manages the life cycle of
an embeddable web applications and provides a
browser common navigation
backstack
Content Providers A Notification Manager that
that enable enables all apps to display
applications to custom alerts in the status
access data from bar
other applications
(such as Contacts),
A Resource Manager,
or to share their
providing access to non-
own data
code resources such as
localized strings, graphics,
and layout files
23. These are the 4 building blocks of
android application .
Activity
IntentReceiver
Service
ContentProvider
Not every
application needs to have all four, but a user’s application will
be written with some combination of these. Once the user has
decided what components are needed for the application, they
should be listed in a file called AndroidManifest.xml, which is
where the components of the application are declared and what
their capabilities and requirements are
24. Activities
• usually a single screen.
• Each implemented as single class.
• most apps consists of multiple screens ,each
screen will be an activity .
• When we switch from one activity to another ,the
older one is paused and put on stack .It is called
back again on resume .
• Android uses a special class called Intent to move
from screen to screen.
25. Intents
Home
Picasa
Photo Gallery
Contacts
“Pick photo”
GMail
Client component makes a
Chat System picks best
request for a specific action
New components can use
component for that action
Blogger
Blogger
existing functionality
26. IntentReceivers
You can use an IntentReceiver when you want code in your
application to execute in reaction to an external event, for
example, when the phone rings, or when the data network
is available, or when it's midnight.
Intent receivers do not display a UI, although they may
display Notifications to alert the user if something
interesting has happened.
Intent receivers are also registered in AndroidManifest.xml,
but you can also register
Your application does not have to be running for its intent
receivers to be called;
the system will start your application, if necessary,
27. Services
A Service is code that is long-lived and runs
without a UI
(IN BACKGROUND).
A good example of this is a media player
playing songs from a play list. In a media
player application, there would probably be
one or more activities that allow the user to
choose songs and start playing them.
28. ContentProviders
A content provider, however, is useful if you
want your application's data to be shared
with other applications.
A content provider is a class that implements
a standard set of methods to let other
applications store and retrieve the type of
data that is handled by that content provider.
30. Common uses of location in apps
1) Plotting a point on a map.
2) Navigation/directions to a point on a map.
3) Finding a local point of interest (nearest ATM ,nearby
restaurants. Etc.
4) Vehicle/traffic tracking
5) Local weather. And countless other things .
Flexible map display and control functions and location
support are provided in Android for mobile system design
31. Location base service
• LBS stands for location based service .
• Location based service is forcasted to be a big
revenue .(Revenue expected to be 10 billion
by 2015 . So it is expected to grow at a high
rate.
KEY CONCEPTS :
1) How do we get the current location
2) Using google map API extension.
32. Location Technologies
network-based
TOA ( Time of Arrival)
Base Station 1
Mobile
T=distance 1

Base Station 2
T=distance 2

33. HOW LOCATION WORKS ?
* Android provides a location framework
- Determine the device’s location
* It can be a combination of GPS and Network Location(Cell
tower and /wi-fi) or just one technology
We then use the Android Location-Based API to collect
user current position and display that location on the screen,
and use Google Maps to display the current user location on
the cell phone.
34. Location Technologies
handset-based
EOTD (Enhanced Observed Time Difference)
Difference 1-3
Base Station 1 Difference 1-2
Clock time 1
Mobile Clock time 2
Base Station 3
Clock time 3
Base Station 2 Difference 2-3
34
36. GETTING CURRENT LOCATION :-
The Android has a LocationManager
- Implement a LocationListener
- Call requestLocationUpdates() passing your
LocationListener
- Can define GPS/Network Location Provider at the same
time
LocationManager will use callback methods' implemented
in LocationListener when :
-Location is changed
- Status of location service changes
For improving performance
-getLastKnownLocation
-min time and min Distance for updating .
37. LOCATION PERMISSION
* Manifest file:user permission request
• -ACCESS_COARSE_LOCATION
• -ACCESS_FINE_LOCATION(GPS AND/OR Network
Location Provider)
Application will fail at without requesting and being granted
necessary permissions .
38. KEY CLASSES :
1) GeoPoint : a pair of latitued and longitude cordinate
2) MapView :displays a map with data obtained from the Google Maps
service
- built in zoom and pan capabilities
- Support for satellite ,traffic and street views
MapView is used to display a view of the map. It can accept the keyboard
events such as onKeyDown and onKeyUp to support the map movement
and the zoom feature. It also supports multi-layer Overlay and user can
draw coordinates,pictures and strings on the map. MapView is set up
only byMapActivity.
3) Overlay : Which can be displayed on top of map like :direction or
compass
39. LOCATION BASED MOBILE SERVICE DESIGN
MAP PROCESS:
-Add maps add-on for google APIs to project
- Multiple versions are available for different API level s
*Manifest file: add<user-library> with com.google.android.maps
-get a MAP API
Sign application with certificate associated with Map API key
40. MapView is required to be added into the layout
create a LocationManager from which we can get the
coordinate values:
41. GETTING CURRENT LOCATION :-
• Dalvik Debug Monitor Server (DDMS)
• Keyhole Markup Language (KML) is an XML notation for expressing
geographic annotation and visualization within Internet-based, two-
dimensional maps and three-dimensional Earth browsers
42. Definition – Reference Point
Reference point: Place taken as a reference
on target path in the cell data collection
process (e.g. bus stop, railway stations)
42
43. Definition – Point of
Interest
Point of Interest (POI): Location that is
interested in the application level (e.g.
building, tourist spot)
43
47. Application in Action (4)
3. The application keeps
track of the location of the
user in the path at each
reference point
47
48. Application in Action (5)
4. Display the information
about the point of interest
(destination)

49. CONCLUSIONS
The feature of location based service is emphasized on
Android platform. One can integrate a fully zoom and
drag enabled map by adding just few lines in the java
code and XML code to the Android-Default-Application.
Through this paper, the availability and performance of
the platform is verified and the design result also shows
the easiness to implement self-location,to perform
queries and to flexibly control the real-time map on
Android. The actual system also achieves high running
performance.
The future work is to design a more powerful mobile
location-based system featured with more unique
customized functions based on Android.
