Push Notification documentation out of date

CameronDWills · September 1, 2022, 12:21pm

I’ve been trying to follow the integration for Push Notifications but the outdated documentation and code has been giving me trouble. First, it tells you to add an older version to your manifest file. 2.0.0-pre2 is the current version as of this post, but the documentation has you add in 1.1.0-pre2.

Also, I tried to add the sample script to register for push notifications found here: Push Notifications SDK documentation | Push Notifications | 2.0.0-pre.2 (unity3d.com)

But the code is wrong. It tells you to call “PushNotificationService.Instance” but this won’t work, because the correct name is PushNotificationsService.Instance

The documentation was also unclear if the firebase SDK needed to be added to the project. When setting up firebase for the first time, and creating the app within firebase to get the app ID, the instructions prompt you to install firebase SDK to your unity project. I also use the Unity Mediation service, which has files that conflict with the firebase SDK (specifically the resolver files), so I deleted the external dependancy manager that came with the Firebase SDK but now I have an error in my project:

TypeLoadException: Could not resolve type with token 01000074 from typeref (expected class 'Google.EditorInitializer' in assembly 'Google.VersionHandlerImpl, Version=1.2.0.0, Culture=neutral, PublicKeyToken=null')

Does the firebase sdk need to be included in the project? What files do I or don’t I need to add if any?

Hi Cameron,
Thanks for pointing that out.
We are still in BETA phase and ironing out some docs.
I’ve messaged our docs team about your reports.

Regarding the FIREBASE SDK:
Our sdk should pull in files needed to make the push notifications run straight out of the box. Firebase is Googles way of handling android notifications… Installing Firebase SDK with our SDK will actually cause more issues. (Duplicate DLLS)

Below is some code that is deprecated but should still work. Put on any game object in your scene. Make sure to install the latest version of Push Notifications SDK

using System;
using Unity.Services.Core;
using Unity.Services.PushNotifications;
using UnityEngine;
using Unity.Services.Analytics;

public class PushNotificationExample : MonoBehaviour
{  
    // Start is called before the first frame update
    async void Start()
    {
        await UnityServices.InitializeAsync();

        // Note: This is the minimum required in Analytics version 3.0.0 and above to ensure the events with the push notification data are sent correctly.
        // In a real game you would need to handle privacy consent states here, see the Analytics documentation for more details.
        await Events.CheckForRequiredConsents();


        // Make sure to set the required settings in Project Settings before testing
        string token = await PushNotifications.RegisterForPushNotificationsAsync();
        Debug.Log($"The push notification token is {token}");

        PushNotifications.OnNotificationReceived += notificationData =>
        {
            Debug.Log("Data retrieved!");
        };
    }
}

Build and release.

Let me know if this helps. I will make sure to go through the new flow as soon as possible and update this post with more relevant code and steps

Best
Seb

Hey Cameron,
I wanted to know if you had any success?
I recently tried the newest version with the latest correct sample and had success on my end.

I could list my steps here if you think that would help while we get the documentation adjusted.

Here are some quick overview steps let me know if I should drill into any steps.

Link your project from the editor by going to EDIT > PROJECT SETTINGS > SERVICES
Make sure you are on ANDROID build
Import the latest Push Notification package into your game
The import should force the right dlls to be pulled.
Make sure you have an account on Firebase
Create a project on the firebase account
Click on Project settings located near project overview
Click on the Service Accounts tab
Click on Generate New Private key (if you don’t already have one)
Save the key and upload it to the unity dashboard under DASHBOARD>LIVEOPS>PUSH NOTICATIONS BETA>SETTINGS > GOOGLE KEYS
In the Unity editor create an empty object and drag and drop the PushNotificationExample.cs from the samples project onto that
Save and compile and run the project test out.
Make sure to save and run for Android
Preferably be connected to a pc when testing so you can see the LOGCAT and search for the “The push notification token is”
Now that you have a token you can test it out by going to DASHBOARD>LIVEOPS>PUSH NOTICATIONS BETA>NOTIFICATIONS
Create a notification with any title any date and any group
On the following screen

8428869--1115868--upload_2022-9-9_16-14-40.png1066×617 124 KB
Click on Test on Device
Paste in your token under the google token
You should receive a notification on your android build

Let me know if you have any questions for the steps above.

The problems for me exist when trying to build the android or iOS versions of the game for release in the app stores. For android, I can’t build at all because I get duplicate class errors (my project uses Unity Mediation, so I’m wondering if there’s conflicting DLL’s) but the error logs don’t help much in finding out what specifically is causing the conflict. And on iOS, I can’t get the xCode project to Archive because I get errors during the build process. Removing the push notifications plugin and trying my build again works perfect, so it’s not until I add push notifications to my project that I can no longer build.

SebT_Unity · September 12, 2022, 3:09pm

Thanks for confirming that Cameron,
Can you search through the assets of your Unity project for : firebase

Could you please send over the screenshot of the DLL’s that may be found when searching for that?

In the meantime I will download the latest version of Unity Mediation and see if any conflicts appear in my test project.
Look forward to hearing from you.

Okay I just added push notifications back to my game and tried to build for android. It failed with these errors:

Thanks for that information!
We are attempting to reproduce locally and will try to have more information for you soon.
In the meantime you can try using the google resolver to attempt to auto resolve the duplicates.

CameronDWills · September 19, 2022, 10:28pm

I haven’t been able to get anything to work any ideas?

SebT_Unity · September 21, 2022, 5:19pm

Hey Cameron,
Can you try reproducing on a blank project? If you do It would be wonderful if you can share the source of that blank project, through a direct message or here.

This would help us repro and get the right teams involve to solve a potential problem.

Look forward to your response.

Lucas7CL · December 6, 2022, 6:52pm

Hi there, any advances in Unity Push Notifications? documentation is not helping too much, and the intuituve very easy to follow steps seem no one have tried them.

SebT_Unity · December 7, 2022, 7:30pm

Hi Lucas,

We are currently overhauling the documentation for push notifications.What platform are you targeting?
I don’t have a date for the doc updates so in the meantime I can help you out trying to get push notifications integrated.

MiTschMR · December 15, 2022, 8:03pm

In the integration documentation (First steps) it is mentioned to add the line "com.unity.services.push-notifications": "3.0.0-pre.1", to the manifest.json for package lookup. However, this package is not found, I am still stuck with 2.0.0-pre.2.

By the way, I have requested access twice now in the last four months and never heard back of anyone… May be worth while to check if the process is still going.

Hi @MiTschMR ,
Thanks for posting on the forums and apologies that no one has replied to your request.
Can you please DM your OrgID so I can have your account flagged with the beta notifications?

The document updates are on their final revision. Thanks for pointing out the version mismatch. The version you have 2.0.0-pre.2. is indeed the latest version.The 3.0.0-pre.1 is a future version.

Look forward to your DM.
Best,
Seb

Hi @SebT_Unity , I get the same error as above.

I am trying to implement push notification version 3.0.0-pre1, after import the package and tried to build for android I get duplicate class errors. I am using firebase, and admob. EDM Force resolve doesn’t solve the problem.

FAILURE: Build failed with an exception.

Execution failed for task ':launcher:checkReleaseDuplicateClasses'.

@SebT_Unity I am out of ideas, do you have any advice how can I solve this?

SebT_Unity · February 3, 2023, 2:58pm

Hi Domonyiv
Reproducing locally and will give you a solution as soon as possible.

The idea here though is that we need to remove one of the two firebase messaging dlls. I just need to document how to do so and will share it here and also ask the docs team to included it for future users.

Ill post back here soon.
Best,
Seb

Hi Domonyiv,

What packages are you using with firebase?
With admob is it an sdk for Unity or a custom implementation?

Thanks for the additional information. The errors I have aren’t the same and attempting to repro to give you a solution. I am getting different errors build failures on my end.

In the meantime if you have backed up your project can you try removing the duplicated
I’ve found the following on stack overflow that may also be help while:

@SebT_Unity

I am using Unity 2021.3.18f, if that matters.

Firebase is added in the manifest.json file and downloaded from here: https://developers.google.com/unity/archive#firebase

"dependencies": {
    "com.google.external-dependency-manager": "file:../GooglePackages/com.google.external-dependency-manager-1.2.174.tgz",
    "com.google.firebase.app": "file:../GooglePackages/com.google.firebase.app-10.1.0.tgz",
    "com.google.firebase.crashlytics": "file:../GooglePackages/com.google.firebase.crashlytics-10.1.0.tgz",
    "com.google.firebase.dynamic-links": "file:../GooglePackages/com.google.firebase.dynamic-links-10.1.0.tgz",

Admob version is 7.3.0 and downloaded from here as a .unitypackage Releases · googleads/googleads-mobile-unity · GitHub

If I add
android.useAndroidX=true
android.enableJetifier=true

the build still fails but all the duplicate classes are prepended by the “jetified-” string.

Execution failed for task ':launcher:checkReleaseDuplicateClasses'.

UPDATE:
I tried it with a new clean project. Added the push notification package then firebase as above, but didn’t added admob and the build failed with the same message.

If I remove the line:
“com.google.firebase.app”: “file:…/GooglePackages/com.google.firebase.app-10.1.0.tgz”,
the build succeed.
So it is clearly a conflict between firebase and push notification.

SebT_Unity · February 8, 2023, 1:00pm

Hi Domonyiv,

Originally I believed it was with the firebase.messaging hence why I pushed you towards that solution, However my understanding is that it’s the whole package? What features do you use from firebase? Do you require firebase for Admob?

I am using version 10.4.0 compared to your 10.1.0

Would it be possible to send that empty project that is failing? This would help us find a solution quicker.

I will bring this to our developers and see what the best way forward is.

Best,
Seb

domonyiv · February 8, 2023, 4:27pm

I am only using firebase for crashlytics (I think it is used by many of the developers) and dynamic links.

I sent a bug report with the project. Here is the issue: Unity Issue Tracker - [Android] Android build fails when using Push notification and Firebase packages
