Firebase Unity Open Source Development

The repository contains the Firebase Unity SDK source, with support for Android, iOS, and desktop platforms. It includes the following Firebase libraries:

Firebase is an app development platform with tools to help you build, grow and monetize your app. More information about Firebase can be found at https://firebase.google.com.

More information about the Firebase Unity SDK can be found at https://firebase.google.com/docs/unity/setup. Samples on how to use the Firebase Unity SDK can be found at https://github.com/firebase/quickstart-unity.

Getting Started

You can clone the repo with the following command:

git clone https://github.com/firebase/firebase-unity-sdk.git

Prerequisites

Please follow Firebase C++ SDK Prerequisites first.

  • Swig, version 4 or newer

Install Unity

  • Unity, version 2019 or newer

While installing through UnityHub, when you decide which version to install, it will pop up a dialog to select necessary support modules. Please check the boxes based on your dev machine OS and dev platform. For most common case while dev on macOS, we should select Android + Android SDK & NDK Tool, iOS Build Support and Mac Build Support (IL2CPP)

Building

Under the repo root folder, call

python scripts/build_scripts/build_zips.py –platform=<target platform>

Note: Supported target platform names: linux,macos,windows,ios,android

Expected output artifact is [Repo Root]/<platform_unity, eg macos_unity>/firebase_unity-< version >-< platform >.zip

Note:

  • Linux zip requires linux machine to build.
  • Windows zip requires windows machine to build
  • macOS, iOS and android zips can be built by mac.(Although android zip could be built on both linux and windows machine as well, but we recommend to run it with mac, to get align with our CI)

Building for certain library

python scripts/build_scripts/build_zips.py —-platform=<target platform> --targets=<lib1> -–targets=<lib2>

Note: Supported library names: analytics, auth, crashlytics, database, dynamic_links, firestore, functions, installations, messaging, remote_config, storage

Packaging

We can package the built artifacts to better imported by Unity Editor.

Packaging unitypackage

Copy the zip file for each platforms to one folder, referred to as assets_zip_dir below, for example usually looks like this

  • firebase_unity-< version >-Android.zip
  • firebase_unity-< version >-Darwin.zip
  • firebase_unity-< version >-Linux.zip
  • firebase_unity-< version >-iOS.zip
  • firebase_unity-< version >-win64.zip

And then run:

python scripts/build_scripts/build_package.py --zip_dir=<assets_zip_dir> –output=<output dir>

Packaging tgz

With the same assets_zip_dir, we can run:

python scripts/build_scripts/build_package.py --zip_dir=<assets_zip_dir> –output=<output dir> --output_upm=True

Packing for certain library

If we build only certain subset of the libraries like in Building for certain library, we can copy the built artifacts into assets_zip_dir, and then run:

python scripts/build_scripts/build_package.py --zip_dir=<assets_zip_dir> -–output=<output dir> --apis=<lib1,lib2>

Including in Project

We can refer to Firebase Unity Installation Options to learn how to import the unitypacakge or tgz files that packaged.
