Do not have acces to use the Windows.Devices.Sms.SmsDevice Apis.

Question

Hi,

I am using following code  when receive an sms in background task.

        public void Run(Windows.ApplicationModel.Background.IBackgroundTaskInstance taskInstance)
        {         
            try
            {

                SmsReceivedEventDetails smsDetails = (SmsReceivedEventDetails)taskInstance.TriggerDetails;

                // search for MobileBroadbandAccount for this DeviceId and get SmsmDevice object
               
                smsDevice = SmsDevice.FromId( smsDetails.DeviceId );
               
                GetSmsMessageOperation getMessage = smsDevice.MessageStore.GetMessageAsync(smsDetails.MessageIndex);
                getMessage.Completed = GetMessageCompletedCallback;
                getMessage.Start();

                System.Threading.Thread.Sleep(1000);
                taskInstance.Canceled += new Windows.ApplicationModel.Background.BackgroundTaskCanceledEventHandler(taskInstance_Canceled);

            }
            catch (Exception e)
            {

            }
      }

        void GetMessageCompletedCallback(Windows.Foundation.IAsyncOperation<ISmsMessage> asyncInfo)
        {

         }

Here I got Exception on GetSmsMessageOperation getMessage = smsDevice.MessageStore.GetMessageAsync(smsDetails.MessageIndex);

What I am missing here? OR I do not have access to use SmsDevice APIs.

Please help as This issue is urgent for me.

Thanks,

Hi Vipin,

What is the exception?  Does the 'Sms SendReceive' sample work for you?

Hi Jeff,

 With my code mentioned above(In C#) for receiving message, I got exception with message: Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED)).

Also I wrote a sample C# code to send SMS also which give me same exception i.e.  The remote procedure call failed.

I also tried javaScript(as C# sample is not available there) Sms SendReceive sample. my observations mentioned below:

1. Able to receive the SMS.

2. Not able to send the SMS. as it gives error on message Box: SMS did not setup: Error: The remote procedure call failed. 

    On subsequent try to send SMS gives  Error:  SMS did not setup: Error: The RPC server is unavailable.

I debugged and found it gives exception with message : The remote procedure call failed. (Exception from HRESULT: 0x800706BE)

 

Note:- I wrote a sample code to received sms and it also working fine in application. but when I use same code in background task it gives me Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED)). 

Please suggest, why I am getting this Catastrophic failure exception while try to receive the SMS as shown in code above. 

 

Thanks,

Vipin
