Call an external app on windows phone 8.1 runtime(not silverlight) xaml c# application

but nothing is working for me as i simply wants to launch one app for eg angry birds from my app using a button click.

Answer 1

If the app has a registered URI , then you should be able to use Launcher.LaunchUriAsync for this. You can also find some help, here at MSDN - How to launch the default app for a URI .

Otherwise I don't think it's possible.

It works for me.

1. setup your app which launch from other.

   add this in WMAppManifest.xaml between < /token> and < ScreenResolutions>

    <Extensions> <Protocol Name="alsdkcs" NavUriFragment="encodedLaunchUri=%s" TaskID="_default" /> </Extensions> 

   add a class "AssociationUriMapper " and override the function "MapUri()"

    class AssociationUriMapper : UriMapperBase{ private string tempUri; public override Uri MapUri(Uri uri){ tempUri = System.Net.HttpUtility.UrlDecode(uri.ToString()); if (tempUri.Contains("alsdkcs:MainPage?id=")){ int idIndex = tempUri.IndexOf("id=") + 3; //3 is the length of "id=" string id = tempUri.Substring(idIndex); return new Uri("/MainPage.xaml?id=" + id, UriKind.Relative); } return uri; } } 

   and call them from other app.xaml.cs at this section of InitializePhoneApplication() function

    RootFrame.UriMapper = new AssociationUriMapper(); // add this line only between RootFrame.Navigated += CompleteInitializePhoneApplication; and RootFrame.NavigationFailed += RootFrame_NavigationFailed; 

2. finally call fron other app to launch an app

    var success = await Windows.System.Launcher.LaunchUriAsync(new System.Uri("alsdkcs:MainPage?id="+5)); if (success){ // URI launched } else{ // URI launch failed } 

   where "alsdkcs" is protocol name.
