Facing Issues while reading Sensor Data in a Service App

I'm trying to get laocation in the Service Application, but I'm facing a lot of errors instead of location data. I'm wondering why the same code works fine in a simple UI Application, I'm sorry about the lengthy post but some of the Errors (from the log file) which I think related to the location tracking, are given below to get an idea about what's going on:

Here's some information about the project:

I followed this tutorial to launch a service app from the host app. Both the host and service applications have the following privileges:

http://tizen.org/privilege/appmanager.launch
http://tizen.org/privilege/location
http://tizen.org/privilege/healthinfo

Using the MessagePort, Both applications communicate with each other like this:

Host App sends a message to Service App about executing a required method.
Service App executes that particular method and sends feedback to the host app (e.g. Location Tracking Started).
Host App recieves the feedback and then updates the UI accordingly.

Here's the sample code which I manipulated for the Location Tracking in my Service App.

Hi,

CAPI_APPFW_APP_CONTROL	app_control.c: app_control_error(116) > [app_control_get_extra_data] KEY_NOT_FOUND(0xffffff82)

Could you check if key-value pair is passed properly for appcontrol's ExtraData? (Please double-check it after uninstalling your apps.)

// In UI APP

    AppControl appcontrol = new AppControl() {
        ApplicationId = Utility.ServiceAppID,
    };
    appcontrol.ExtraData.Add("location", "start");
    Tizen.Log.Info(Program.LOG_TAG, "####   ExtraData : " + appcontrol.ExtraData.Count());
    if (appcontrol.ExtraData != null)
    {
        foreach (string s in appcontrol.ExtraData.GetKeys())
        {
            Tizen.Log.Info(Program.LOG_TAG, "####   key = : " + s);
        }
    }

// In Service App

protected override void OnAppControlReceived(AppControlReceivedEventArgs e)
{
    base.OnAppControlReceived(e);
    
    Tizen.Log.Info(LogTag, "####   ExtraData : " + e.ReceivedAppControl.ExtraData.Count());
    if (e.ReceivedAppControl.ExtraData != null)
    {
        foreach (string s in e.ReceivedAppControl.ExtraData.GetKeys())
        {
            Tizen.Log.Info(LogTag, "####   key = : " + s);
        }
        string type = e.ReceivedAppControl.ExtraData.Get<string>("location");
        if (string.Compare(type, "start") == 0)
        {
            LocationService.Instance.StartLocationService();
        }
        else if (string.Compare(type, "stop") == 0)
        {
            LocationService.Instance.StopLocationService();
        }
    }
}

In addition, please check if <background-category> is declared in tizen-manifest.xml file to get location data even if the app is running in the background.

Please check out the sample code.

Thanks.

Hi,

Thank you so much for the detailed response along with the Sample Code. I'm sorry for being a bit late (was stuck somewhere else).

By following your guidelines about the background-category I'm getting the Heart Rate from the Service.

But I'm still getting some errors in getting Location from the Sensor.

I would be greateful if given some guidance on the log file data from your Sample Application:

In the following section:

I is for Info
W for Warning
E for Error

I'm facing the following error in my Application as well:

LBS_SERVER_GPS    dump_log.c: gps_dump_log(302) > Add dump log [timestamp [1567547624], sat num [0] view num [0] used [0]

Following all your guidelines regarding privileges and background category, Is there any issue with my device behaviour ? I'm using Samsung Gear S3 Frontier.

Hi,

LBS_SERVER_GPS dump_log.c: gps_dump_log(302) > Add dump log [timestamp [1567547624], sat num [0] view num [0] used [0]

It is not an error log message. It is just a normal log to get information about some location parameters.

Thanks.

Hi,

Thanks a lot for the continous guidance. I thought it's an error because it's level is set as an "Error" in the logs and not "Info" or anything else. I have checked again and noticed that I'm not getting the locaion because the service state is not being changed after the Locator has been started successfully.

The weird thing is that other sample apps which were working fine, Now also behaving the same way.
I have also reset the device but it didn't work.

A little R&D makes me believe that the GPS of Samsung Smart Watch is not efficient enough to work always and sometimes it behaves weird and sometimes any other issue can be faced.

I have found the following information about Location Framework in a white paper (Page 42):

The LBS plugin is implemented based on the Tizen LBS server for a vendor-specific GPS device.

The LBS plugin is implemented as a shared library and the lbs-server loads a specific LBS plugin at runtime. AnLBS plugin mustbe written with predefined interfaces. The lbs-server-plugin-dev source package is installed on OBS by adding the following command in the package spec file:

BuildRequires: pkgconfig(lbs-server-plugin)Within thelbs-server-plugin-dev package, thesource files are locatedin:
/usr/include/lbs-server-plugin/*.h
/usr/lib/pkgconfig/lbs-server-plugin.pcThe gps_plugin_intf.h

file includes the API interfaces for the communication between the lbs-server and its GPS plugin

This is the configuration for Native Application. Do we have any such packages to be configured for using Location as Service in Tizen .NET as well?

If yes, then how can I ensure that I've configured the lbs server kinds of things correctly in my .NET application ?

Hello

NET application internally use Native APIs.

Both Native and .NET application use the same plugins.
