Where is my bus is tool that helps students to track where their school buses are in real time. This project is composed by three clients apps (Android, iOS and Web mobile) and one tracker app. Each school bus has a low-end android device with the tracker app installed in it, every time the buses move 20 meters the app pushes the new location to a real-time firebase database and notify all the clients that the position has changed. This is the home for the source code of the android app, is written using java and firebase BaaS. We are open improvements, if you like 😍 the app and think that there is something missing, or perhaps you want improve something, just do it!. We are looking forward to hear from you.
