The aim of this bachelor’s thesis is to extend the mobile application of Zoo Brno with the possibility to play recorded stories of each animal. The app must be able to play the records without the internet connection. In case of the missing record, it enables a user to download a package with the record. Because the app is primarily designated for Zoo Brno visitors, to prevent animals from disturbing , it only allows playing of stories with headphones plugged in or device put near the ear of a user. The result of the thesis is an extension of the application implemented for Android and distributed in Google Play.
