Hello i want to create a scheme URI to launch my app from another app. I searched a lot, i found this tutorial URI associations, it shows how to register your app for A URI association but it is for Windows Phone 8. I am developing an app for Windows Phone 8.1 RT and none of the tutorials i found work. At least I'd like to know if it is supported on WP 8.1 RT.
The term you're looking for is protocol activation. You can have a look at the official Association launching sample.
In short: you configure your protocol in your appxmanifest and handle activation in you App.xaml.cs code behind.
protected override void OnActivated(IActivatedEventArgs args)
{
if (args.Kind == ActivationKind.Protocol)
{
ProtocolActivatedEventArgs protocolArgs =
args as ProtocolActivatedEventArgs;
var rootFrame = new Frame();
rootFrame.Navigate(typeof(BlogItems), args);
Window.Current.Content = rootFrame;
}
Window.Current.Activate();
}
