Remarks

Windows 8.1 allows users to message their contacts from the Contact Card or Windows Search experience. By implementing the contact message activation contract, Windows can launch your app to send messages for the user.

To receive message activations, your app must register for the "windows.contact" extension category in its manifest. Under this extension, you must include a "LaunchAction" element with the "Verb" attribute equal to "message." You can then specify the "ServiceId" element to specify the type of messaging you support. For example, if your app handles standard text messages, you can specify a "ServiceId" of "telephone." If your app handles messaging over a web based service, like Skype, you can specify the domain name of that service, for example "skype.com."

If multiple apps have registered for this contract, the user can choose one of them as their default for handling messages.

Here is an example for manifest registration:


<m2:Extension Category="windows.contact" xmlns:m2="http://schemas.microsoft.com/appx/2013/manifest">
  <m2:Contact>
    <m2:ContactLaunchActions>
      <m2:LaunchAction Verb="message" DesiredView="useLess">
        <m2:ServiceId>telephone</m2:ServiceId>
      </m2:LaunchAction>
      <m2:LaunchAction Verb="message" DesiredView="useLess">
        <m2:ServiceId>skype.com</m2:ServiceId>
      </m2:LaunchAction>
    </m2:ContactLaunchActions>
  </m2:Contact>
</m2:Extension>

After you register in your manifest, your app can be activated for the contact message contract. When your app is activated, you can use the event information to identify the message activation and extract the parameters that help you complete the messaging scenario for the user.

Examples

Here is an example of the code you need to handle contact message activations for PSTN numbers and Skype Ids:

protected override void OnActivated(IActivatedEventArgs args)
{
    if (args.Kind == ActivationKind.Contact)
    {
        var contactArgs = args as IContactActivatedEventArgs;
        if (contactArgs.Verb == Windows.ApplicationModel.Contacts.ContactLaunchActionVerbs.Message)
        { 
            IContactMessageActivatedEventArgs messageArgs = contactArgs as IContactMessageActivatedEventArgs;

     //get contact display info
     var contactName = messageArgs.Contact.DisplayName;
            var contactThumbnail = messageArgs.Contact.Thumbnail;

            if (messageArgs.ServiceId == "telephone")
            {
                var phoneNumber = messageArgs.ServiceUserId;
                //add messaging logic for PSTN numbers
            }
            else if (messageArgs.ServiceId == "skype.com")
            {
                var userId = messageArgs.ServiceUserId;
                //add messaging logic for Skype Ids
            }
        }

    }
}
void App::OnActivated(IActivatedEventArgs^ args)
{
 if (args->Kind == ActivationKind::Contact)
 {
  auto contactArgs = dynamic_cast<IContactActivatedEventArgs^>(args);
  if (contactArgs->Verb == Windows::ApplicationModel::Contacts::ContactLaunchActionVerbs::Message)
  {
   auto messageArgs = dynamic_cast<ContactMessageActivatedEventArgs^>(contactArgs);

       //get contact display info
auto contactName = messageArgs->Contact->DisplayName;
   auto contactThumbnail = messageArgs->Contact->Thumbnail;

   if (messageArgs->ServiceId == "telephone")
   {
    auto phoneNumber = messageArgs->ServiceUserId;
    //add messaging logic for PSTN numbers
   }
   else if (messageArgs->ServiceId == "skype.com")
   {
    auto userId = messageArgs->ServiceUserId;
    //add messaging logic for Skype Ids
   }
  }
 }
}

Use the Contact property to collect additional info about the contact that is being messaged. The contact can have a name and thumbnail that can be used to represent it in your app’s UI. Or, the contact can have alternative user ids that can be used in case the primary user id is unavailable. The ConnectedServiceAccounts property contains a list of all services available for the contact. You can use the ContactConnectedServiceAccount.ServiceName and ContactConnectedServiceAccount.Id properties on each service to retrieve alternative services and user ids respectively.

Here are possible Contact properties that can be populated during a message activation:
