It stack includes an operating system, a middleware and a few applications. Google provides an android SDK for developing android applications. The SDK is available on all major platforms – Windows Linux and Mac OSX and is free download from [6]. We developed our application on the Android 1.1 SDK release 1. The development was done the Eclipse IDE for Java using the Android Development Tool (ADT) plug-in. Instructions for installing the SDK and ADT can be found here [7]. 3.

The certificate is used to identify the authors of applications and to build trust among applications. More information on application signing can be found here [9]. Android provides a Maps API to help developers use and integrate Google Maps with their mobile applications. However, in order to use the Maps API the developers have to register withGoogle Maps service and agree to certain Terms of Service. More information on registering ...
