The Cloud Storage for Firebase Unity Sample demonstrates the Firebase SDK for Cloud Storage with the Firebase Unity SDK inside the Unity Editor.

• Unity The quickstart project requires 2017.4 or higher.
• Xcode 10.3 or higher (when developing for iOS).
• Android SDK (when developing for Android).

• Download the Firebase Unity SDK and unzip it somewhere convenient.
• Open the sample project in the Unity editor.
  • Select the File > Open Project menu item.
  • If Unity Hub appears, click Add. Otherwise click Open.
  • Navigate to the sample directory testapp in the file dialog and click Open.
    • You might be prompted to upgrade the project to your version of Unity. Click Confirm to upgrade the project and continue.
• Open the scene MainScene.
  • Navigate to Assets/Firebase/Sample/Storage in the Project window.
  • Double click on the MainScene file to open it.
• Import the Firebase Storage plugin.
  • Select the Assets > Import Package > Custom Package menu item.
  • From the Firebase Unity SDK downloaded previously, import FirebaseStorage.unitypackage from the directory that matches the version of Unity you use:
    • Unity 5.x and earlier use the .NET 3.x framework, so you need to import the dotnet3/FirebaseStorage.unitypackage package .
    • Unity 2017.x and newer allow the use of the .NET 4.x framework. If your project is configured to use .NET 4.x, import the dotnet4/FirebaseStorage.unitypackage package.
  • When the Import Unity Package window appears, click the Import button.
• Turn off secure access using Public Rules
  • Navigate to the Storage tab in the firebase console.
  • In the Rules section, replace the line allow read, write: if request.auth != null; with allow read, write;
• Change the line private const string MyStorageBucket = "gs://YOUR-FIREBASE-BUCKET/"; to replace YOUR-FIREBASE-BUCKET with the bucket found in the firebase console under the Storage tab.

Once you have done this, you can run the Unity Editor and test the application. You will be able to enter text to upload to Cloud Storage and afterwards download that same text.

• Register your iOS app with Firebase.
  • Create a project in the Firebase console, and associate your iOS application.
    • You should use com.google.firebase.unity.storage.testapp as the iOS bundle ID when creating the Firebase iOS app in the console.
      • If you do not use the prescribed Bundle ID, you will later need to update the bundle identifier in Unity as described in Optional: Update the Project Bundle Identifier below.
• Add the GoogleService-Info.plist file to the project.
  • Navigate to the Assets/Firebase/Sample/Storage folder in the Project window.
  • Drag the GoogleService-Info.plist downloaded from the Firebase console into the folder.
    • NOTE: GoogleService-Info.plist can be placed anywhere under the Assets folder.
• Optional: Update the Project Bundle Identifier
  • If you did not use com.google.firebase.unity.storage.testapp as the iOS bundle ID when creating your app in the Firebase Console then you will need to update the sample's Bundle Identifier.
    • Select the File > Build Settings menu option.
    • Select iOS in the Platform list.
    • Click Player Settings
    • In the Settings for iOS panel scroll down to Bundle Identifier and update the value to the iOS bundle ID you provided when you registered your app with Firebase.
• Build for iOS
  • Select the File > Build Settings menu option.
  • Select iOS in the Platform list.
  • Click Switch Platform to select iOS as the target platform.
  • Wait for the spinner (compiling) icon to stop in the bottom right corner of the Unity status bar.
  • Click Build and Run.

• Register your Android app with Firebase.
  • Create a project in the Firebase console, and attach your Android app to it.
    • You should use com.google.firebase.unity.storage.testapp as the Android package name while you're testing.
      • If you do not use the prescribed package name, you will need to update the bundle identifier as described in the Optional: Update the Project Bundle Identifier below.
    • Android apps must be signed by a key, and the key's signature must be registered to your project in the Firebase Console. To generate a SHA1, first you will need to set the keystore in the Unity project.
      • Locate the Publishing Settings under Player Settings.
      • Select an existing keystore, or create a new keystore using the toggle.
      • Select an existing key, or create a new key using "Create a new key".
      • After setting the keystore and key, you can generate a SHA1 by running this command:

        keytool -list -v -keystore <path_to_keystore> -alias <key_name>
        

      • Copy the SHA1 digest string into your clipboard.
      • Navigate to your Android App in your firebase console.
        • From the main console view, click on your Android App at the top and click the gear to open the settings page.
      • Scroll down to your apps at the bottom of the page and click on Add Fingerprint.
      • Paste the SHA1 digest of your key into the form. The SHA1 box will illuminate if the string is valid. If it's not valid, check that you have copied the entire SHA1 digest string.
  • Download the google-services.json file associated with your Firebase project from the console. This file identifies your Android app to the Firebase backend, and will need to be included in the sample later.
    • For further details please refer to the general instructions which describes how to configure a Firebase application for Android.
• Add the google-services.json file to the project.
  • Navigate to the Assets/Firebase/Sample/Storage folder in the Project window.
  • Drag the google-services.json downloaded from the Firebase console into the folder.
    • NOTE: google-services.json can be placed anywhere under the Assets folder.
• Optional: Update the Project Bundle Identifier
  • If you did not use com.google.firebase.unity.storage.testapp as the Android package name when you created your app in the Firebase Console, you will need to update the sample's Bundle Identifier.
    • Select the File > Build Settings menu option.
    • Select Android in the Platform list.
    • Click Player Settings
    • In the Settings for Android panel scroll down to Bundle Identifier and update the value to the package name you provided when you registered your app with Firebase.
• Build for Android
  • Select the File > Build Settings menu option.
  • Select Android in the Platform list.
  • Click Switch Platform to select Android as the target platform.
  • Wait for the spinner (compiling) icon to stop in the bottom right corner of the Unity status bar.
  • Click Build and Run.

• When upgrading to a new Firebase release: import the new firebase unity package through Assets > Import Package > Custom Package as above. After the import is complete you may need to run the Assets > Play Services Resolver for the changes to be reflected in the editor. If issues persist, delete the plugin and install it again.
• Android: After exiting the editor and returning you will need to reconfigure the Project Keystore in Player Settings > Publishing Settings. Select your Custom Keystore from the dropdown list and enter its password. Then, select your Project Key alias and enter your key's password. enabled in your project, you'll see compile errors from some types in the
