What is App-to-App Communication?

In the beginning…

Your App

Extending apps with the phone

What about the other way…?

Extending the phone with apps

And finally…

Custom URI AssociationsLaunch other apps to complete tasksPlay an album on Spotify

Play a video in YouTube

Post an update to Facebook

Launch device settings

Link your app into core experiencesBrowser

Messaging

EmailLauncher.LaunchUriAsync(new Uri("myapp:foo=1&bar=2"));

Useful Built-in URI AssociationsTask URI Scheme

Launch by file:Foo.bar

TokenID = 1234

Get handlers for ‘.bar’

Data Sharing Service

Create file brokering token

Target AppLaunch target

Redeem token for file

User Experience

Guiding PrinciplesUser is always in controlApps cannot take over an extension

The list of installed apps is private user dataApps cannot query installed apps, URI associations, or file extensions

Standard tasks should be simple and predictableStandard types are handled by built-in experiences

One Handler

Launch URI: skype:call?5551234

No handlers

2+ Handlers

What’s happening in the wild?

App Launching via ProximityTarget apps• Your app can be launched based on a URI sent from another

device• Handler code is exactly the same• Proximity capability is not required

Source apps• You can launch apps on other devices using the Proximity

APIs
