Web System for interlocutor's Availability

Abstract

It is inevitably noticeable that mobile technologies are increasingly occupying a central place in today's world. Currently, they form the fastest growing technologies and it can easily be concluded that a generation of smart mobile devices has started. Today, there are four billion active users of mobile phones and one billion users are familiar and are using smartphones. Also, for two to three years, we are expecting accession to the Internet from mobile devices to surpass joining the Internet via desktop devices [1]. This situation requires more work and research in this area, so that we can create new and useful mobile applications that hopefully in the future might become necessary in everyday situations. However, developing mobile applications is not only creating the software that runs on any portable device with low power and with limited operating system’s and platform’s features. Creating a mobile application means to design and create entire systems with components of different nature that will exist individually and independently but will provide all the data and functions that a mobile application needs. Briefly, mobile phones cannot, and should not carry large processing or large data. Their duty is only in such communication with external systems. This paper will present a system of multiple components, with special focus on a mobile application that will enable new, so far unknown function for all users of the Android operating system. Namely, it is a system which provides fast information about the availability of interlocutors. It is presented in an intuitive way on the device display, and the same information is taken from the user’s calendars. All details will be presented in the following chapters.
