I'm trying to add a hyperlink in fb messenger. Basically I'm creating a chatbot that replies users questions. However when I want to link the user to a webpage the only way possible is if I type in... For iPhone, there exists the fb:// URL scheme, but trying the same thing on my Android device throws an ActivityNotFoundException. Is there a chance to open a Facebook profile in the official Facebook app from code? Check the Live Running Status on redrail for 22130. Here, you can find real-time tracking details of your train, including its location, delay status, expected arrival and departure time at various stations, platforms, and more. How do I go about either making, or retrieving facebook short url's (fb.me) from a page, profile, event etc? I want to update my url shortener site - but if the user links to a facebook page I want to just return a fb.me link instead. Does facebook make their short urls on the fly, or does each page automatically already have one?
