Twitter client tends to redirect to web browser When clicking a Twitter's link on GMail client, Twitter client is included in the list of possible applications to process. So I click Twitter but then the list window pops up again but this time without Twitter in it. I really like to open a link to Twitter with Twitter client. How can I do that? Thank you!

A sample of those Twitter links looks like this:
https://twitter.com/i/redirect?url=https%3A%2F%2Ftwitter.com%2FRescue_moco%3Frefsrc%3Demail&amp;sig=d4724ad41f731911a0eeacd4eb0764b30186d3af&amp;uid=37758565&amp;iid=am-1618412813699712373452051&amp;nid=23+1100&amp;t=1

The Twitter app registers an intent filter for http and https URLs to twitter.com, to tell Android it can open those URLs itself. That's why you get the first chooser (the list of possible apps).

However, it seems that the Twitter app can't actually understand those "redirect" links, so it asks for a web browser to handle the URL. That's why you get the second chooser, with only web browsers.

Since the page does in fact redirect to a Twitter user (which the app can handle), after you've opened the URL in a browser you should get a third chooser, which does include Twitter, allowing you to open the user in the Twitter app. However, Firefox currently has a bug that means it won't offer a chooser in this case. If you pick Chrome in the second chooser, it should give you the third chooser.

I'd call this a bug in the Twitter app. You should complain to Twitter and ask them to fix it.
