3. Android is the first open source smartphone OS
Developers enjoy a comprehensive software development kit, with
ample tools for developing powerful, feature-rich applications.
The Open Handset Alliance announced the Android platform and
launched a beta program for developers.
As android OS keeps on upgrading rapidly so for developing
applications for upgraded OS SDK version are also upgraded
Android IN short…….

4. Peril alert is an android application. The central concept of the
application is to provide safety to the user in hazardous conditions.
The word ‘PERIL’ defines a condition in which a person is stuck!
And needs HELP!!
It helps the user to reach his friends or family by using certain type
of short messaging services. With no efforts the user can simply
convey the ‘DANGER SITUATION’ to his nearest rescue person.
It uses Android’s Peer-to-Peer (P2P) text and data communication
protocols, specifically instant messaging and SMS.

5. To develop a system that uses the short messaging service to instantly
send our location which can be determined using the global
positioning service provided in the smartphones. The application can
help us to rescue from a hazardous situation by sending the location to
our friends.

6. Use the Google maps to trace the location and in a click the location
is sent through the SMS.
Instead of calling someone and asking for help, this is more
preferable and can get help in a short time.
In case of recording an evidence, the recording function can also be
used.
Storing a number and the message with the latitude and longitude of
our present location can be send.

12. Basic Methodology
10/7/2013 12Android Application for Peril Alerts

13. This android application is implemented using two programming
languages
• Java
• XML(Extended Mark-up language)
Why to use XML programming language?
• User Interfaces (UI) in Android can be built within two ways, by
defining XML-Code or by writing Java-Code.
• XML is highly preferable, because as one knows that the UI should
always be separated from the program-logic.
• After declaring the layout structure in XML we use java to define
the actions that the objects in layout should perform.
