Educational Technology is constantly evolving and growing, and this progression will continually offer new and interesting advances in our learning environment. Traditional E-Learning systems developed for laptop and desktop computers were based on stand-alone software application or through websites and lack the ability to provide a comprehensive ubiquitous learning environment. A ubiquitous learning environment based on early days mobile phones lack the processing power of notebooks or desktop computers, low data transfer speeds and capacity. However, the ability to provide a comprehensive ubiquitous learning environment on the 3G (3rd Generation) mobile device will offer powerful collaborative and interactive learning opportunities. Thus the main objective of the research work is to develop an interactive mobile learning application based on Web Services in Android base mobile devices to facilitate the ubiquitous learning. This paper deals with the prototype development of an MLearning application for mobile phones running with Android platform using Web services.
