There are 4 | just a few small guidelines you need to follow. 5 | 6 | ## Contributor License Agreement 7 | 8 | Contributions to this project must be accompanied by a Contributor License 9 | Agreement (CLA). You (or your employer) retain the copyright to your 10 | contribution; this simply gives us permission to use and redistribute your 11 | contributions as part of the project. Head over to 12 | to see your current agreements on file or 13 | to sign a new one. 14 | 15 | You generally only need to submit a CLA once, so if you've already submitted one 16 | (even if it was for a different project), you probably don't need to do it 17 | again. 18 | 19 | ## Code reviews 20 | 21 | All submissions, including submissions by project members, require review. We 22 | use GitHub pull requests for this purpose. Consult 23 | [GitHub Help](https://help.github.com/articles/about-pull-requests/) for more 24 | information on using pull requests. 25 | 26 | ## Community Guidelines 27 | 28 | This project follows 29 | [Google's Open Source Community Guidelines](https://opensource.google/conduct/). -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.

Tapping a bus stop on the first 7 | screen will display a list of all arrival times for that particular stop. 8 | 9 | The bus stops are stored in a Room database. Schedule items are represented by the `Schedule` class 10 | and queries on the data table are made by the `ScheduleDao` class. The app includes a view model to 11 | access the `ScheduleDao` and format data to be display in a list. 12 | 13 | # Pre-requisites 14 | * Experience with Kotlin syntax. 15 | * Experience with Jetpack Compose. 16 | * How to create and run a project in Android Studio. 17 | * Basic knowledge of SQL databases and performing basic queries. 18 | 19 | # Getting Started 20 | 1. Install Android Studio, if you don't already have it. 21 | 2. Download the sample. 22 | 3. Import the sample into Android Studio. 23 | 4. Build and run the sample. -------------------------------------------------------------------------------- /app/build.gradle.kts: -------------------------------------------------------------------------------- 1 | /* 2 | * Copyright (C) 2023 The Android Open Source Project 3 | * 4 | * Licensed under the Apache License, Version 2.0 (the "License");
