The world of information technology is in continuous evolution. New, more capable devices and technologies emerge constantly, introducing ways not previously known in the field of communication, orientation, gathering information and countless other activities.
During the past decade, the Internet went through dramatic changes: on many newly opened sites, users are the providers of content. Various social sites have been formed, where anyone can share what s/he thinks, creates or discovers. In the meantime the World Wide Web has become available on the ever-evolving mobile devices. Anyone can share things from wherever s/he is, and other people can access them from anywhere: thanks to smartphones, they can see and hear these things as the owner does. With the help of these devices, they are able to look around somewhere in a way that all the information that is available about that place could appear on the screen held on their palm.
These innovations were combined, creating location-based social applications. In this way, conventional maps can be replaced with knowledge bases built of user contributions.
The aim of the COPI project is to create a such tool for the most popular smartphone platforms. Using the application users can mark points of interest, which can be rated, tagged or commented on. They can create questionnaires, which anyone coming by a given place can fill.
This thesis is about enhancements to the media management capabilities of COPI for Android. There is a dedicated chapter for each feature, containing the detailed documentation, supplemented with diagrams and screenshots. At the end of each chapter, there is a short user documentation illustrated with screenshots.
The first implemented feature introduces the support of photo, voice or movie recordings as answers in location based questionnaires, these can be the sources of valuable extra information. The other two solved tasks deal with the user-friendly and efficient presentation of media content: they create the user interface for both an overview of attachments to a place and the detailed view of a piece of content. After each chapter, there is a short discussion of further development possibilities.
