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

It's also the subject of my talk "[Connect 5 | your Android Things with Firebase][1]". 6 | 7 | There are three components to this project: 8 | 9 | - An Android Things app (the doorbell) 10 | - A companion app (homeowner app) 11 | - A backend implemented with Cloud Functions 12 | 13 | The Android Things app lives under "thing", and the companion app lives 14 | under "app". They both need to be added as apps to a Firebase project. 15 | The backend lives under "backend" and should be deployed to the same project 16 | with the Firebase CLI. 17 | 18 | The latest version of the slides of the related talk can be found on 19 | [SpeakerDeck][1]. There are some slides with code and a helpful system 20 | diagram that shows how the following Firebase and Google APIs were used: 21 | 22 | - Cloud Firestore 23 | - Cloud Storage 24 | - Cloud Messaging 25 | - Cloud Functions 26 | - Nearby 27 | 28 | **NOTE**: A service account is required for the Cloud Functions code to 29 | run correctly. The script under `backend/scripts/config-env.sh` will help 30 | you get your service account file added as an env var to deploy with the 31 | functions. 32 | 33 | ## Watch the session 34 | 35 | Recorded at Droidcon VN: 36 | 37 | [![Video of session](https://img.youtube.com/vi/F-zq8xOntEE/0.jpg)](https://www.youtube.com/watch?v=F-zq8xOntEE) 38 | 39 | ## License 40 | 41 | The code in this project is licensed under the Apache License 2.0. 42 | 43 | ```text 44 | Copyright 2018 Google LLC 45 | 46 | Licensed under the Apache License, Version 2.0 (the "License");
