The most common Smart phone platforms available today are Android, Windows and IOS. Android, being the only open source platform for mobile devices offers a lot of scope in the field application development. Android is a software platform and operating system for mobile devices developed by Google and the open handset alliance.
The purpose of our Android based application for making rescue calls is to make people feel safe even when they are in an emergency situation. The application can be activated before getting into an emergency situation, say before walking alone to a tunnel. On the press of a button, the device will send an emergency SoS to a friend or the police along with the current position and video to another device.
We develop this application using “Eclipse” IDE (Integrated development environment) which uses the Android SDK (Service development kit). Once the application has been coded it will be tested on an Android virtual device (AVD). This application can be installed on all Mobile Phones supporting Android and can be used during an Emergency.
