How can I get the Steps and Floors Goals so I can show it?

Hello,

Is it possible to get the heart rate sensor data when the screen is off ? I tested the HeartRateMonitor sample but when the screen goes to sleep, the returned value is 0 on the event OnDataUpdated().

Best regards,

Hello, All!
I need to send periodical vibration from wearable service application (like here: https://github.com/Samsung/Tizen-CSharp-Samples/blob/master/Wearable/ServiceApp/ServiceApp/ServiceApp_App.cs)
I try to use alarms for this: https://docs.tizen.org/application/dotnet/guides/alarm/alarms/#scenario_1
For example I've tried to set alarm to send notification:

protected override void OnCreate()
        {
            base.OnCreate();

            Notification notification = new Notification
            {
                IsVisible = true,
                Title = "TestNotification",
                Content = "This is a test notification",
                Count = 3
            };

            Notification.AccessorySet nAccessory = new Notification.AccessorySet
            {
                SoundOption = AccessoryOption.On,
                CanVibrate = true,
                LedOption = AccessoryOption.On
            };
            notification.Accessory = nAccessory;

            Alarm alarm = AlarmManager.CreateAlarm(1, 2, notification);
        }

But when I run this service application on Tizen Emulator I don't see any alarms. May you explain please how to create alarm from wearable service application, and, maybe there better solution for preiodical vibration realization then alarm ?

Hello

I have the following open topic with Microsoft where abviously it has to be double checked by Samsung
https://github.com/MicrosoftDocs/xamarin-docs/issues/2675

In this issue, I simply wanted to add Tizen related project in this Xamarin.Form Sample:
https://docs.microsoft.com/en-us/samples/xamarin/xamarin-forms-samples/todo/

Can you please have a look on the attached files?
Todo.zip

Many thanks

Many samples use hard coded app path.
It does not guarantee the fixed path on platform

Must use DirectoryInfo class
(https://samsung.github.io/TizenFX/master/api/Tizen.Applications.DirectoryInfo.html)
Tizen.Applications.Application.Current.DirectoryInfo

Hi.
Is there any customization of the video player so that it can work with ChromeCast?

Hello,
I am testing the sample .NET Code for Maps provided in this area (https://github.com/Samsung/Tizen-CSharp-Samples/tree/master/Wearable/Maps) and it seems that no pin image loads when a new pin is added to a mep.

var pin = new Pin(new Geocoordinates(DEFAULT_LAT, DEFAULT_LON));
s_mapview.Add(pin);

This works for a Mobile application, but not Wearable. Is this a known limitation of the platform or does the pin need a special sizing for Wearables?

Hello, does anyone knows how to change TV input source on Samsung TV?
The documentation looks like exactly what I need, but this is for the web application, as I understand.
Here I see only the ability to get info about Display.

Does anyone know how to change source to HDMI using Tizen.Net for xamarin?
Thanks

Hello!
I've created the Service application for Samsung Watch based on your code template.
I need tp add some custom parameters for my service application (for example, hours, when application will start and stop). Unfortunatelly I have not so much expirience in Tizen development and may you explain, please - what is a best way for this decision ?
Perhaps, you may provide the link to decription of custom Tizen service configuration.
Thank you.

Hello,

I'm sorry if this is bad place to ask this question. Do you have a solution to keep a Tizen Wearable C# application in foreground when the screen goes to sleep ?

I would like to develop an activity tracker for sport and therefore always have the application visible but not necessarily the screen on.

Thank you for your answers.

Xaml preview not rendering - "An Android Application project must reference the project containing this XAML file in order to render in the Previewer"
Is something is missing ?

To be able to build the samples on VS 2019, the below is concerned.

Hello there , I just started to read about Tizen and the ability to do so with Xamarin .
I just cannot find a sample of video player for the TV ,
I tried to clone git://git.tizen.org/profile/tv/apps/dotnet/sample/videoplayer but it has no files.

the other topic that might be answered if I have managed to clone that solutoin is : do you have a recommended pattern to handle the events coming from the remote to navigate between different controls ?

Hello
Based on the following article, the function WebView.EvaluateJavaScriptAsync is not implemented on Tizen.Net plateform
https://docs.microsoft.com/en-us/dotnet/api/xamarin.forms.webview.evaluatejavascriptasync?view=xamarin-forms
Is there another way to read cookies?

I tried using different SkiaSharp versions, but that didn't help.

I can't find any app example for the AnimationView API in the repository. I'm interested in developing a TV CSharp Xamarin.Forms app which uses json (rlottie) animations. Could you add a sample app which renders a json animation? Thank you.

Hi, I asked this question already on the Tizen app developers forum but since it's also related to this repository, I will repeat it here. Having the development tools set up (latest Tizen SDK, emulator, etc.) I can't build the project because of missing Tizen.Xamarin.Forms.Extension package. It was unlisted from nuget:

https://www.nuget.org/packages/Tizen.Xamarin.Forms.Extension/

and the latest version there was 2.3.5-v00009 while the projects here reference it at version 2.4.0-v00014. How can one build the sample then?

Hi,
I want to start an Tizen TV application with c# and I would like to know if i create the Xaml UI with Xamarin.Forms, do i get TV remote controller support? I can navigate menus and give input using remote controller?
I know that same thing for Xbox using XF, it is not possible to use joystick or remote controller with xamarin.forms uwp. Only native UWP works.
is it the same for Tizen and XF?

thanks for the help

Currently it doesnt seem to create a companion app using xamarin. because Samsung accessory sdk has only Jar support. I tried using Android Java bind library but it throws exception. please provide us a minimal working solution. you can find my attempt to create using xamarin.forms with dependency injection as attached.

I imported the tizen sensors sample application into visual studio 2019. Using tizen package manager I installed certificate extension. Then, I created a new Samsung wearable certificate using tizen certificate manager. When I am trying to run the app on my connected wearable device, the visual studio keeps giving the following error:
processing result : Check certificate error [-12] failed
Please, help me to solve this error!

I'm on Visual Studio 2019 Community for Windows with a Samsung Gear Sport updated to Tizen 4.0.0.4.

In the sample https://github.com/Samsung/Tizen-CSharp-Samples/tree/master/Wearable/SpeechToText

Once compiled and deployed to the device for debugging, in VS I get:

**Frame not in module

The current stack frame was not found in a loaded module. Source cannot be shown for this location.**

App just crashes and slows down the watch until I reboot. If I copy all of the files to a new VS project, it will compile and deploy, but once I tell it to record and it stops recording after silence detection, I get a "Service Error - Operation Failed" message on the device and no speech to text recognition.

Hi, DotnetPolicyChecker is blocking the CubeWithSkiaSharp example app from being run with a message "[FAIL] SkiaSharp.dll refers a forbidden assembly directly - libEGL.dll" on Tizen 5.0. Is there a way to resolve this issue or maybe you can suggest other high-level C# library that is capable of rendering text, isn't blocked on Tizen TV and can be used in tandem with OpenTK?

Hello,

I'm trying to make a Google Drive App.
I've made all the steps from the home page, have the latest version for the VS Plugin and Tizen SDK (as asked here: https://github.com/Samsung/Tizen-CSharp-Samples/issues/31)
I've used Google's .NET Quickstart guide (https://developers.google.com/drive/api/v3/quickstart/dotnet) in a console application, in which it works perfectly, but in the Tizen 5.0 Class Library (added to the Blank App Xamarin Form) I stumble only on "Segmentation Fault".

The first one is when it's trying to read the credentials.json file (which was added to the solution and set to be copied to the location of the executable).
I've fixed this by using StorageManager.Storages and looking for the Internal StorageType, then created the file, if it didn't exist, and adding the json to it (using System.IO.File). I've also replaced "new FileStream("credentials.json", ...)" with "System.IO.File.Open(credentialsPath, ...)".
The only hint I had for this was the call stack which indicated that there was a problem when accessing the memory (see first image).

The second one is when it tries to call AuthorizationAsync. Unfortunately this it the first place in which I couldn't figure out what I should do because the call stack wasn't of help (see second image).

The third one is when I've tried a new approach. This one goes further, but fails when it tries to get the files from the service. The call stack shows that there is a memory access problem, but I can't figure out what might cause this (see third image).
Screenshots: https://imgur.com/a/J6mkfYe

I have the following privileges in the manifest: internet, network.get, mediastorage, systemsettings, externalstorage, filesystem.read, filesystem.write. The last five were added thinking that they are the fix for the first problem and I've left them just in case.

Is there a way to get more information on the actual error or is there a correct way of doing a connection with Google Drive ?

Thank you,
Flavius

I have a TV with platform tv-samsung-4.0, hospitalbility TV
I use C# on visual studio 2019, when I debug (start without debugging), nothing happen.
When I see the command line, the "sdb shell" not working.

So how can I debug on Smart TV model 2018?
By the way, can it run the .Net application?

I’ve been playing with the Tizen .NET SDK for Wearables to write an app for my Samsung Galaxy Watch Actvie2. I’m using these sample apps as a guide (they have been very helpful).
There is one thing that I’d like my app to do that I can’t figure out. How do I prevent the screen from timing out and changing to the Off display state? I’ve seen other apps do this, so I’m assuming it’s possible. I don’t see any sample that’s doing this kind of thing, but I’m also not sure what to look for. I tried creating a Display.StateChanged event handler that detects when the state changes to Off and then changing it back to Normal, but that isn’t working.

Any help would be greatly appreciated.

Hi Team
Is there a way to retrieve IMEI & cell information like mcc,mnc,lac,cell etc via Tizen dotnet api's?

Hello,

Is there a way to store data in tizen .net? I.E data generated by your app stored on said wearable device. As I have been looking around and have not been able to find a way to do this.

Thank you for any help provided.

:)

Thank you for making this sample. Do you have a Cordova Web app version? I am unable to get Tizen's instructions working for reading NFC.

I'm guessing there's something wrong with the manifests - none of the TV apps seem to appear in the apps list / smarthub, so there's no way to launch these apps on the TV without doing it remotely from Visual Studio.

I am exploring Tizen-CSharp-Samples/Wearable/Xamarin.Forms/Location sample and in my watch the ListView is not correctly aligned to center.

The text is mostly correctly aligned, but visible button area is a little bit off from center as you can see from the screenshots from my watch.
Also, after installation or returning to the app after long time, the app does not react to physical ring bezel. I wiping works for scrolling. After going into any subpage and coming back to main list the bezel is working.

My watch:
Galaxy Watch DA5A
SM-R800
One UI v2.0
Tizen 5.5.0.2

Project build in Visual Studio 2019 with packages:
Tizen.NET 9.0.0.16760
Tizen.Wearable.CircularUI 1.5.0

Hello there , I am making a renderer for the MultimediaView . However , when it executes base.OnElementChanged(e); I get an error Segmentation fault what do you guys do when this happens ? how can you find out the problem ?

Hi everyone,

In the example PushReceiver .NET.
in the PushModel class, i can see string AppId = "**Your Push App ID**";.

Can anybody tells me how to generate the Push App ID for .NET?

i'm really new in xamarin, and i need the notification for my final studying project .

Thanks in advance.

There isn't a sample to do a call from associated smartphone. Is it still used the privilage "http://tizen.org/privilege/call"?
