40. Android Platform Android is a software stack for mobile devices that includes an operating system, middleware and key applications.  Application framework  Dalvik virtual machine  Integrated browser, Media support, Optimized Graphics, SQLite, Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model.

41. Android Implementation Our robust design easily leveraged the facilities provided by Google's Android. Android provides excellent integration with Google's location based and map services.  Location Providers – whereami, gps (mock, for now) etc...  Map Controller, Overlay Controller Implementation of our service is in the form of an overlay on the base map service.

43. Android Advantage Focussed on the Developer, lots of documentation and a powerful, well structured API. Very good integration with web-services (although not complete), including Google's own. Android is based on several open-source technologies.

45. Challenges 1. Figuring out IMS 2. Power v/s Frequency of querying WhereAmI 3. Bandwidth for maps
