Universal Store Apps
Emanuele Garofalo
What’s new

Perché?
Condivisioni a livello di piattaforma di sviluppo
• API set
• App model
• Live Tiles
• App distribution format
• Controlli
Condivisioni a livello di servizi
• Un solo store
• Shared app identities + entitlement
• Unified Push Services (WNS)
• Unified App Data Roaming and backup

Sembra entropia…ma non lo è
Serve a darti la…retro-compatibilità

APPX for everyone
(tranne che per Silverlight)
• In questo modo le risorse sono organizzate in bundle
• Si riducono le dimensioni dei download
• Non c’è molto da fare da parte nostra se usiamo le risorse

// Simple navigation, no parameters

// Passing a simple type, like an ID or an object
Frame.Navigate(typeof(PaginaTarget), “21");
Rispetto alla navigazione
basata su URI abbiamo
il vantaggio di poter passare
parametri di ogni tipo e
non solo testuali

Integrazione con il Notification Center
Cosa devo fare per integrarmi con il notification center?
(quasi) NIENTE!

Integrazione con il notification center
//Scegliete un template
ToastTemplateType toastTemplate = ToastTemplateType.ToastText02;
//Recuperatene l’xml
XmlDocument toastXml =
ToastNotificationManager.GetTemplateContent(toastTemplate);
//trovate i tag text
XmlNodeList toastTextElements = toastXml.GetElementsByTagName("text");
//settate il valore dei tag
toastTextElements[0].AppendChild(toastXml.CreateTextNode(toastHeading));
toastTextElements[1].AppendChild(toastXml.CreateTextNode(toastBody));
//scegliete la durata della notifica toast
IXmlNode toastNode = toastXml.SelectSingleNode("/toast");
((XmlElement)toastNode).SetAttribute("duration", "long");
//create la toast notification
ToastNotification toast = new ToastNotification(toastXml);
//Mostrate la toast
ToastNotificationManager.CreateToastNotifier().Show(toast);

Integrazione con il notification center
Per mostrare la notifica solo nel notification center:
toast.SuppressPopup = true;
NB: Se l’utente scegliesse di non mostrare le vostre
notifiche sarebbe tutto (ovviamente) inutile

Integrazione con Cortana
Operazione in tre step
Creare il nostro file
con la definizione dei
comandi vocali
Registrare i comandi
vocali all’avvio
dell’applicazione
Gestire l’attivazione
da comandi vocali

Comandi Vocali
<VoiceCommands xmlns="http://schemas.microsoft.com/voicecommands/1.1">
<CommandSet xml:lang="en-us" Name="englishCommands">
<CommandPrefix> MyApp </CommandPrefix>
<Example> tweet 'welcome to mobileday' </Example>
<Command Name="Tweet">
<Example> tweet 'welcome to mobileday' </Example>

<ListenFor> tweet </ListenFor>
<ListenFor> tweet {dictatedSearchTerms} </ListenFor>
<Feedback> tweeting </Feedback>

<Navigate Target="Tweet.xaml" />
</Command>
<PhraseTopic Label="dictatedSearchTerms" Scenario="Search">
<Subject> twitter </Subject>
</PhraseTopic>
</CommandSet>
</VoiceCommands>

Comandi Vocali
string voiceCommandName;
if (NavigationContext.QueryString.TryGetValue("voiceCommandName", out
voiceCommandName))
{
HandleVoiceCommand(voiceCommandName);
}
else
{
// If we just freshly launched this app without a Voice Command, asynchronously try to
install the
// Voice Commands.
// If the commands are already installed, no action will be taken--there's no need to
check.
Task.Run(() => InstallVoiceCommands());
// Just for fun, we'll also animate the home page buttons
FadeInfoButtons(true);
}

Comandi Vocali
private async void InstallVoiceCommands()
{
try
{
bool using81orAbove = ((Environment.OSVersion.Version.Major >= 8)
&& (Environment.OSVersion.Version.Minor >= 10));
Uri vcdUri = new Uri("ms-appx:///VoiceCommandDefinition_8.1.xml");
await VoiceCommandService.InstallCommandSetsFromFileAsync(vcdUri);
}
catch (Exception ex)
{
//Gestione dell’errore
}
}

Comandi Vocali
void HandleVoiceCommand(string voiceCommandName)
{
string textToTweet = null;
bool tweet = false;
switch (voiceCommandName)
{
case "Tweet":
if (NavigationContext.QueryString.TryGetValue("naturalLanguage", out
phraseTopicContents)
&& !String.IsNullOrEmpty(phraseTopicContents))
{
NavigationContext.QueryString.TryGetValue("dictatedSearchTerms", out
textToTweet);
SendTweet(textToTweet);
}
break;
//…altri comandi…
}
}
