Bus Scheduler App

This folder contains the source code for the Bus Scheduler app codelab.


The Bus Scheduler app displays a list of bus stops and arrival times. Tapping a bus stop on the first screen will display a list of all arrival times for that particular stop.

The bus stops are stored in a Room database. Schedule items are represented by the Schedule class and queries on the data table are made by the ScheduleDao class. The app includes a view model to access the ScheduleDao and format data to be display in a list, using Flow to send data to a recycler view adapter.


  • Experience with Kotlin syntax.
  • Familiarity with activities, fragments, and recycler views.
  • Basic knowledge of SQL databases and performing basic queries.
