In Windows Phone 8, is it possible to determine source app when Launcher.LaunchUriAsync was called from that source application?

Question

My windows phone 8 app is associated with an URI scheme ( myapp: ). When other apps use Launcher.LaunchUriAsync ( http://msdn.microsoft.com/library/windows/apps/hh701476 ) and call my uri scheme, is it possible to determine the name or namespace app that initiated the launch?

I have looked around and have not found an official way to do it. Any help is appreciated, thank you!

Answer 1

There's no way to know which apps launched yours. One workaround is to educate developers launching your app and ask them to add a referrer parameter:

myapp://yourUrl?referrer=NameOfTheApp

Still, you won't be able to know the name of the app is the caller omits the parameter.
