I need to open Facebook and Twitter App from my app, that points to a specific Facebook Page and Twitter profile.

Which is the best way to do this?

Thanks in advance...

Answer 1

Try this :

Device.OpenUri(new Uri("fb://page/page_id"));
Device.OpenUri(new Uri("twitter://user?user_id=userid"));

For page_id right click on page and select view source page and find the page_id for facebook and same as for twitter find the userid

In addition to accepted answer, following are my finding to open links in external applications.
To open link in browser:

Device.OpenUri(new Uri("http://example.in/index.html"));

To open group in facebook:

Device.OpenUri(new Uri("fb://group/groupname"));

To open page in facebook:

Device.OpenUri(new Uri("fb://page/page_id"));

To open user in instagram:

Device.OpenUri(new Uri("instagram://user?username=yourUserName"));

To open user in twitter:

Device.OpenUri(new Uri("twitter://userName?user_id=userId"));

To open mail app:

Device.OpenUri(new Uri("mailto:[e-mail]"));
