I wanted to ask couple questions about the Book being promoted on this forum, and this question is based on my own experience.
A while ago I developed mobile tracking application that is integrated with an online application, two of the major problems were:
1- I've tried to use standard J2ME classes, but I was surprised to find out that the functionality that is offered as standard set of feature is limited on different devices. I've considered developing a web application that is accessible from the device.
2- although that I've tried to simulate actual tracking units in my application, publishing the application and generating a revenue out of it was "and still" a problem: I know the possibilities of the technology now "at least on BlackBerry" but I couldn't come up with a business model that I can enforce with the application: how to sell it? how to control the licensing of it? ... etc. most of the location aware application that I know "maybe I'm wrong" are social oriented which are published and used freely. how to create a business model out of location aware mobile application.
I hope that such a book which is promoted here clears these issues.
