Recuring Job only called once in Blazor Hybrid App

[konrad79]

I've a Blazor Hybrid App with Shiny and .NET8.
I want a background task run recurrently every N seconds or minutes.

I registered the job in the Programm.cs:

public static MauiApp CreateMauiApp()
{
 var builder = MauiApp.CreateBuilder();
 builder
    .UseMauiApp<App>()
    .UseShiny()
    .ConfigureFonts(fonts =>
    {
       fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
    });

 builder.Services.AddMauiBlazorWebView();
          
#if ANDROID
 var job = new JobInfo("MyJobName", typeof(MyJob), RunOnForeground: false, null , RequiredInternetAccess: InternetAccess.Any, DeviceCharging: false, BatteryNotLow: true, IsSystemJob: false);            
 builder.Services.AddJob(job);
#endif

#if DEBUG
 builder.Services.AddBlazorWebViewDeveloperTools();
 builder.Logging.AddDebug();
#endif
 return builder.Build();
}

(I've to use the #if ANDROID because of errors otherwise)

And in the Job itself I defined the MinimumTime (no documentation found for this parameter - hoping it's the right one):

public class MyJob : Job
{
    public MyJob(ILogger<MyJob> logger) : base(logger)
    {            
        this.MinimumTime = TimeSpan.FromSeconds(10);
    }

    protected override async Task Run(CancellationToken cancelToken)
    {
        // DO SOMETHING LIKE CALLING AN API AND SHOW NOTIFICATION
    }
}

The code in the Run function is only called once at the startup of the app.

What am I missing?

And are there older versions, because I found a lot of examples using Job parameters like "Repeat = true", "PeriodicTime = ..." and others, that doesn't exist in Shiny.NET for .NET8 (anymore?).

Jobs don't work like that. Periodic != Scheduled. The OS truly decides how often things run. MinimumTime is used to ensure it doesn't run too often.

The current samples don't have this. Docs are behind though.

Thanks, Allan.
Then I can say goodbye to my idea of having a background process call an API every 5 minutes - and then having a push notification pop up under certain conditions
