Abstract

In the contemporary society of knowledge and two-way interhuman communication information is acquired, processed, stored, retrieved, transmitted and spread in real time and at minimal cost. During the last decade, an exponential increase in the use of up-to-date instant messaging applications has been noted. Specifically, the function of exchanging messages in real time has currently prevailed over communication via electronic mail on a personal level, while it has started gaining ground in professional talks as well. The most popular instant messaging applications for smart devices are enriched with additional functions, besides sending and receiving text, which allow the users to exchange photographs, videos, emoticons (icons with facial expressions to show emotion) and some common type files, such as, for example, Word documents and Excel spreadsheets. In the wider context of the present postgraduate dissertation a fully featured Android instant messaging application through Cloud Messaging (GCM) has been developed; namely a complete system of two-way communication in real time which optimizes the homonymous free service of Google and applies it to smart devices with an Android operating system. The particular service, which is described thoroughly in this dissertation, offers a steady channel of exchanging information through which the following can be transmitted at no cost; on the one hand, the messages that are sent by an Application Server to one or more conjugate and certified GCM client applications – namely the downstream GCM messages, on the other hand, the messages that are sent by a GCM client application to a given and familiar Application Server– namely the upstream GCM messages. In accordance with the demands of the times the devised GCM Android Application provides the users with the ability to instantly exchange text messages and images in an adaptable, minimalistic and easy to use Graphical User Interface GUI environment which has been developed on the basis of the totality of the designing rules of Google’s Material Design.
