如何打开 Facebook 应用程序以在 WP8 上共享链接？

Question

I wonder how to open the official Facebook App for sharing an URI from my C# code on Windows Phone. The common Uri-Scheme like "fb://" may open the App but no parameter seems to work. I have something like this in mind, but it will not work for me:

LaunchUriAsync(new Uri("fb://publish/profile/me?text=foo"));

Of course I know that I could use the ShareTask but that's not what I want. You can take a look at the Spotfy App, it does exactly, what I want to do, when sharing a song.

Thank you for your help and answers!

PS: Same with Twitter by the way...

Answer 1

I finally solved it! It took me nearly two days to find the solution and it is not documented anywhere sothat I would like to share my results with you:

// Open official Facebook app for sharing
await Windows.System.Launcher.LaunchUriAsync(new Uri("fb:post?text=foo"));

I think this is a very cool feature and reminds users of how it works on other plarforms.

In conclusion launching other apps from your app via URI schemes is always a great scenario with a nice user experience.

Hint : Opening the official Facebook App via URI schemes requires at least version 4.1!

Answer 2

If you wanna share the link, you can use ShareLinkTask

ShareLinkTask shareLinkTask = new ShareLinkTask();
shareLinkTask.Title = "My Title";
shareLinkTask.LinkUri = new Uri("http://fb.me/profile.php", UriKind.Absolute);
shareLinkTask.Message = "Yep. I can share a link on facebook.";
shareLinkTask.Show();

When user calls this method, it will show the sharable social networking apps installed on the phone, so you can share a link on the facebook, twitter & etc (if installed)

If you wanna share the local media file, you can use ShareMediaTask
