I have used this forum as a resource while l have learnt to develop android application, and am very thankful for all the help I have been able to extract from previous posts. I am now glad to be able to make my first post to promote my application "Distance and area measurement". It is an application that uses the GPS to measure the area of a region you souround by carrying the mobile around it. It come in one free version that can be obtained from the ordinary market, and one paid, ad free version, that can be obtained from SlideMe.org. Feel free to download, use, and comment on it.
