Quote:If I can write a mobile application that give me information about the people whose I have their mobiles numbers stored in my mobile, the application should give exactly where and how far they are from my position or the distance between me and them and the direction.
This application should give a notification list of people withen 200 meters around me.
It is possible to write such a application- But.......
1. The people who are in your phonebook must share their GPS location to the server from where your mobile application fetched the location. For that , the people will have to install the same application on their mobile.
2. The application must be able to identify the device from the mobile number.
Use GPS locations to calculate the distances.
Quote:If that possible; what is the best programming language that can be used and the hardware components that might be needed to implement this project?
Android,iPhone , Windows Phone SDK can be used. No specific hardware. A server which has a GPS service. GPS enabled devices. Development environment for app development.
Quote:What should I need to learn to be able to perform this project ?
