Disable GPS autostart

[FREE2WIN2]

Is there a way to disable the GpsManager to auto start?
I don't even know who would want to automatically start gps tracking when the app starts.

I tried with manually adding the Gps and working with subscirptions instead of the GpsDelegate, but nothing worked yet.
Is there a way or do I need to swithc to another library/write it my own?

GPS will auto start if you request a background start on it. It will keep doing this until you stop the listener in your code.

I tried with manually adding the Gps and working with subscirptions instead of the GpsDelegate, but nothing worked yet.

You need to add some sort of sample of what you mean. I have no idea what you mean here or why it wouldn't work.

But it starts automatically on app start as the gps managers are a IShinyStartupTask, which should not be a problem when no currentSetting is set but magically its always set (idk from where)

I tried this:

1. Use general gps registration without delegate
   builder.Services.AddGps();
   instead of
   builder.Services.AddGps<MyGpsDelegate>();

2. request with listener:

var request = new GpsRequest
      {
        BackgroundMode = GpsBackgroundMode.Realtime,
        Accuracy = GpsAccuracy.Normal,
        DistanceFilterMeters = 0,
      };

      var r = await this.gpsManager.RequestAccess(request).ConfigureAwait(false);
      if (r == AccessState.Available)
      {
        this.gpsManager.WhenReading().SubscribeAsync(this.HandleLocationChangeAsync);
        try
        {
          await this.gpsManager.StartListener(request).ConfigureAwait(false);
        }
        catch (Exception e)
        {
          Console.WriteLine(e);
        }
      }

This works, but also when just starting the app without the Listener started.
And what do you mean with background start?

[aritchie]

This request says that GPS should run in the background.

var request = new GpsRequest
      {
        BackgroundMode = GpsBackgroundMode.Realtime,
        Accuracy = GpsAccuracy.Normal,
        DistanceFilterMeters = 0,
      };

This call

await this.gpsManager.StartListener(request).ConfigureAwait(false);

Will make it run automatically if the app is swiped away and then restarted until you call IGpsManager.StopListener

builder.Services.AddGps();

Running your GpsRequest with backgroundmode and realtime arg is not right and should cause an error. If you don't want GPS to run in the background, you should just use GpsBackgroundMode.None. V3 doesn't auto start if those values aren't set and it shouldn't persist unless a background mode is set.

[FREE2WIN2]

I use v3.3.4.
And I changed the backgroundmode to none now. But even when I uninstall the app and reinstall it the gps permission is instantly requested and the gps tracking started.
Even when I stop the tracking (StopListener) the gps tracking starts automatically after app reinstallation. When i only restart the app after stopping the gps tracking it does not start automatically.

This is my delegate

  public partial class MyGpsDelegate : GpsDelegate
  {
    public MyGpsDelegate(ILogger<MyGpsDelegate> logger)
      : base(logger)
    {
      this.MinimumDistance = Distance.FromMeters(0);
      this.MinimumTime = TimeSpan.FromSeconds(15);
    }

    /// <inheritdoc />
    protected override Task OnGpsReading(GpsReading reading)
    {
      Console.WriteLine("ON Gps reading! {0} {1}", reading.Position.Latitude, reading.Position.Longitude);
      return Task.CompletedTask;
    }
  }

It doesn't work no matter if i use background mode or not.

Can you please submit a reproducible sample project? Is this Android or iOS?

[FREE2WIN2]

I had the issues on Android. You can find the code here:
FREE2WIN2/ShinySample

Tbh its not reproducible . I don't know why actually, but in this example it seems fine and I got to know many things.
I think the main issue is resolved as I did not know about the Background functionality. Also I will just stop the listener when my main activity is destroyed.

Thank you very much for your support. It helped me a lot. And sorry for my not-understandable descriptions.
