E Contact is an application developed in
Android platform to help the app users in emergency situations. This
Android based E Contact app can be used as a mobile app to contact
different departments such as hospital, fire station, blood bank,
police, ambulance and other emergency contacts. Even people with speech
disorders can use this application to communicate with other people
about their problems.
E contact works as a mobile app and can
be installed in android tablets. The full source code and project report
of this android app project is available in the download links provided
in this post. Below, I’ve briefly introduced the architecture and
details in this project. You can their detailed information in the
project report itself.
E Contact Android App Project Abstract:
- After installing the E contact app, you should enter your details and register. Registration requires details such as name, contact number, emergency contact name plus number and blood group.
- Under “Settings” you can update your along with your emergency contact details.
- If someone wants your phone number, they can update their details. So, this eradicates the complexity of uninstalling and installing the E contact app again.
- Emergency contact number can be contacted or accessed under “Help” option.
- Hotlines can be rescued under “SOS” option.
- Under “Blood Bank” option, there is a feature to send requests for blood group by sending a SMS to all the contacts. The details under this include the current location the user and the blood group required.
- Hospitals, police, ambulance, fire stations, etc. can also be search via the features available in the app.
System Architecture:
The E Contact Android app was developed
to have a working app at all times. The final version comes with Google
maps. Also, distributing and implementing the app was managed very
effectively so that there are less conflicts and regressions in this
android application.
Rather than proposing an app with less
features, this application is a fully functioning one compared to a
unstable version with more features and functions. The project involved
the use of SQLLite as the database for storing information. It
implements a self-contained, server less, zero-configuration,
transactional SQL database engine.
Android simulator was used to check the
working of E Contact and the app was checked for compatibility with API
10 as the target API. Google maps API is used to locate the co-ordinates
of the nearest service points. The below is the description of how the
modules that were used in the App Design interact to produce the desired
result.
The registration module is used to
collect user details and the emergency contacts information and store
them. The maps module dynamically retrieves location co-ordinate
information from the google maps API. The other modules dynamically
retrieve location from the google maps server and use them to provide
related information to the user with respect to the service the user has
requested.
Conclusion:
As stated in the project report, the
future improvements in Android based E Contact app include getting the
hotline numbers dynamically based on the location in which the user is
present. With this feature incorporated in the app, people outside USA
can easily use this app. Further, a feature to send a text message to
911 can also be introduced into the E Contact app.
