Is DotNet 7 MAUI supported?

[SteveSitekitcare]

Hi

I have a basic example of a MAUI app built on dot net 7. The target is only android. I added the google-services.json (not in the source due to security)

I also added the analytics package and configured. I dont see anything in firebase even though the app works?

Code sample is here (just add a google-services.json file) https://github.com/SteveSitekitcare/Plugin.Firebase.net7.0

Cheers

I can say that it works for NET7.0, im currently using it; the app works as it runs or as it receives notification? I looked at your code and you are missing the configuration in the Android part (Android manifest and Mainactivity.cs)

Hi

I dont see any instructions for the manifest? The mainactivity.cs is only mentioned when using the emulator?

Can you emphasise on what exactly I'm missing?

[Paulpetta668]

Im referring to this for the android manifest. Then u need to create the channel, this i done in the mainactivity.

My MainActivity.cs

protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);
    HandleIntent(Intent);
    CreateNotificationChannelIfNeeded();
}

protected override void OnNewIntent(Intent intent)
{
    base.OnNewIntent(intent);
    HandleIntent(intent);
}

private static void HandleIntent(Intent intent)
{
    FirebaseCloudMessagingImplementation.OnNewIntent(intent);
}

private void CreateNotificationChannelIfNeeded()
{
    if(Build.VERSION.SdkInt >= BuildVersionCodes.Tiramisu)
    {
        if(ContextCompat.CheckSelfPermission(this, Manifest.Permission.PostNotifications) != Permission.Granted)
        {
            ActivityCompat.RequestPermissions(this, new[] { Manifest.Permission.PostNotifications }, 0);
        }
    }

    if (Build.VERSION.SdkInt >= BuildVersionCodes.O)
    {
        CreateNotificationChannel();
    }
}

private void CreateNotificationChannel()
{
    var channelId = $"{PackageName}.general";
    var notificationManager = (NotificationManager)GetSystemService(NotificationService);
    var channel = new NotificationChannel(channelId, "General", NotificationImportance.Default);
    notificationManager.CreateNotificationChannel(channel);
    FirebaseCloudMessagingImplementation.ChannelId = channelId;
}

public override void OnRequestPermissionsResult(int requestCode, string[] permissions, [GeneratedEnum] Permission[] grantResults)
{
    Platform.OnRequestPermissionsResult(requestCode, permissions, grantResults);
    base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
}

This looks likes its for the messaging side of firebase, Im using analytics and crashlytics? I dont use messaging

[Paulpetta668]

Oh, my bad, i know for sure that this plugin work for NET7.0, i dont know for analytics and crashalytics, sry if i wasted your time

I'm also struggling greatly to get this working in .net 7 Trying to figure our which nuget packages are required to get the code samples working, as the ones in the examples I see for .net 6 are not playing well together and causing additional issues.

Would love to see the example code here updated to .net 7 https://github.com/TobiasBuchholz/Plugin.Firebase/blob/development/sample/Playground/MauiProgram.cs

Hi, I'm trying to use Firebase authentication with .net7 but when I try to create a user it keeps blocking me, here I leave you the link to my project: https://github.com/criss02-cs/ToDoListMaui When I try to register the user I get the line var user = await Auth.CreateUserAsync(Email, Password); and it gets stuck there and never comes out

@Paulpetta668 could you post a simple sample that works - somewhere :-)

[ahoymehearties]

Adding to the chorus of "how the eff do we do this in .NET 7." :) Microsoft recommends binding directly to libraries and links to a 44 minute video of a guy with a super thick accent doing a powerpoint, which is not great.

For those in the peanut gallery, I was able to achieve this very easily with OneSignal as a firebase intermediary.

Check the .NET MAUI docs here

Those instructions do not make any sense for me. After speaking to there support team, they dont actually support maui yet.

I got the app running but it has exactly the same issue as plugin.firebase, the implemenation was null

[TobiasBuchholz]

Maui with .net7 is definetly supported, the sample and test projects are using it now as well as the dedicated demo project of @andyzukunft.

[shaboboo]

I am unable to get the playground sample code (from master branch) to compile.

In Playground.MauiProgram.cs neither CrossFirebase.Initialize or FirebaseAuthGoogleImplementation.Initialize can be found.

I will try the dedicated demo next

Edit: Wasn't able to get the demo to fully compile either, but the MauiProgram.cs IS able to call the initialize function at least. I feel safe enough to make another attempt to this working in my own solution

Edit 2: In both my project and the dedicated demo project above, I am hitting exception trying to get device token await CrossFirebaseCloudMessaging.Current.GetTokenAsync();

Message: "Default FirebaseApp is not initialized in this process pbsconnect.sales.droid. Make sure to call FirebaseApp.initializeApp(Context) first."

This is the same issue I was hitting before, not sure how to resolve.
