Android based real time projects - III

The new platform for Smartphone  is the Android OS,  launched by Google, which is growing at faster rate.  Android provides the support for location services. Development of location based applications is complex and difficult. This paper introduces the architecture and component models of Android, and analyzes the anatomy of an Android application including the functions of Activity, Intent Receiver, Service, SMS, and etc. Based on Android, the design method of a location-based mobile service is then presented. The design example shows that it's so easy to implement location application which fetches latitude and longitudinal values and sends through the desired phone number.

Drunk driving, or officially Driving Under the Influence (DUI) of alcohol, is a major cause of traffic accidents throughout the world Today. In this paper, we are proposing a highly efficient system aimed at early detection and alert of dangerous vehicle maneuvers typically related to drunk driving. The entire solution requires only a android based device, which  can be placed in vehicle and with accelerometer sensor. A program installed on the device computes accelerations based on sensor readings, and compares them with typical drunk driving patterns extracted from real driving tests. Once any evidence of drunk driving is present, the mobile phone will automatically alert the driver or message to specific number for help.
