Firebase Data Connect Quickstart

Introduction

This quickstart is a movie review app to demonstrate the use of Firebase Data Connect with a Cloud SQL database. For more information about Firebase Data Connect visit the docs.

Getting Started

Follow these steps to get up and running with Firebase Data Connect. For more detailed instructions, check out the official documentation.

0. Prerequisites

Latest version of Android Studio
Latest version of Visual Studio Code
The Firebase Data Connect VS Code Extension

1. Connect to your Firebase project

If you haven't already, create a Firebase project.
1. In the Firebase console, click Add project, then follow the on-screen instructions.
Upgrade your project to the Blaze plan. This lets you create a Cloud SQL for PostgreSQL instance.

Note: Though you set up billing in your Blaze upgrade, you won't be charged for usage of Firebase Data Connect or the default Cloud SQL for PostgreSQL configuration during the preview.
Navigate to the Data Connect section of the Firebase console, click on the "Get Started" button and follow the setup workflow:
- Select a location for your Cloud SQL for PostgreSQL database (this sample uses us-central1). If you choose a different location, you'll also need to change the quickstart-android/dataconnect/dataconnect/dataconnect.yaml file.
- Select the option to create a new Cloud SQL instance and fill in the following fields:
  - Service ID: dataconnect
  - Cloud SQL Instance ID: fdc-sql
  - Database name: fdcdb
Allow some time for the Cloud SQL instance to be provisioned. After it's provisioned, the instance can be managed in the Cloud Console.
If you haven’t already, add an Android app to your Firebase project, with the android package name com.google.firebase.example.dataconnect. Click Download google-services.json to obtain your Firebase Android config file.

2. Cloning the repository

Clone this repository to your local machine:

git clone https://github.com/firebase/quickstart-android.git

Move the google-services.json config file (downloaded in the previous step) into the quickstart-android/dataconnect/app/ directory.

3. Open in Visual Studio Code (VS Code)

Open the quickstart-android/dataconnect directory in VS Code.
Click on the Firebase Data Connect icon on the VS Code sidebar to load the Extension. a. Sign in with your Google Account if you haven't already.
Click on "Connect a Firebase project" and choose the project where you have set up Data Connect.
Click on "Start Emulators" - this should generate the Kotlin SDK for you and start the emulators.

4. Populate the database

In VS Code, open the quickstart-android/dataconnect/dataconnect/moviedata_insert.gql file and click the Run (local) button at the top of the file.

If you’d like to confirm that the data was correctly inserted, open quickstart-android/dataconnect/movie-connector/queries.gql and run the ListMovies query.

5. Running the app

Press the Run button in Android Studio to run the sample app on your device.
