Get Started with Firebase Storage for Unity

Firebase Storage lets you upload and share user generated content, such as images and video, which allows you to build rich media content into your apps. Firebase Storage stores this data in a Google Cloud Storage bucket, a petabyte scale object storage solution with high availability and global redundancy. Firebase Storage lets you securely upload these files directly from mobile devices and web browsers, handling spotty networks with ease.

Before you begin

Before you can use Firebase Storage, you will need to create a Firebase project, and add the Firebase Unity SDK packages to your Unity project.

Setup:

Prerequisites

If you don't have a Unity project already, you can download one of our quickstart samples and experiment with a specific Firebase feature. If you're using a quickstart, remember to get the bundle identifier from the project settings; you'll need it for the next step.

Set up your app in Firebase console

To add Firebase to your app you'll need a Firebase project and a Firebase configuration file for your app.

Create a Firebase project in the Firebase console, if you don't already have one. If you already have an existing Google project associated with your mobile app, click Import Google Project. Otherwise, click Create New Project.

Add the Firebase Unity SDK to your app

1. Download the Firebase Unity SDK
2. Select the Assets > Import Package > Custom Package menu item.
3. Import the FirebaseStorage.unitypackage package from the Firebase Unity SDK, downloaded previously.
4. When the Import Unity Package window appears, click the Import button.

Build your app

Setting up public access

Storage provides a declarative rules language that allows you to define how your data should be structured, how it should be indexed, and when your data can be read from and written to. By default, read and write access to Storage is restricted so only authenticated users can read or write data. To get started without setting up Authentication, you can configure your rules for public access. This does make Storage open to anyone, even people not using your app, so be sure to restrict your Storage again when you set up authentication.

Access the FirebaseStorage class

The Firebase.Storage.FirebaseStorage is the entry point for the Firebase Storage Unity SDK.

// Get a reference to the storage service, using the default Firebase App
Firebase.Storage.FirebaseStorage storage = Firebase.Storage.FirebaseStorage.DefaultInstance;

If you have chosen to use public access for your rules, you can proceed to the sections on saving and retrieving data.

Setting up restricted access.

If you do not want to use public access you can add Firebase Authentication to your app to control access to Firebase Storage.
