About the project

Jibberin allows you to send free messages and make calls to other users on any device through any network around the world. The application has the ability to send text messages, make both ordinary and video calls between users, add friends to different groups, report new events and maintain a joint calendar for organizing various events.


In the application the opportunity is realized to group contacts and chats by interests, spheres or in any other way convenient for the user.

In groups, it is possible to exchange messages, photos, intersections, files. There is also the possibility of joint planning of events.


Any member of the group can create new chats, as well as make them private for a certain range of contacts. Users have the opportunity to file complaints against participants whom they consider not relevant.

In the conversation itself there is a standard functional: the invitation of users, the requirement to render ban to users, as well as the request to make the conversation private. The decision on these requests is made by the chat administrator - the user who created it.


Data exchange with the server was implemented using the Retrofit library. Storage and exchange of data is carried out using Firebase. Notifications of new events were realized with the help of EventBus, which greatly simplified the interaction with the life cycle of the application. Loading and caching images was entrusted to Universal Image Loader. Serialization and deserialization of data was carried out by the library from Google - Gson.

At this time, the application is available on Google Play.
