For my app WristTweets, I implemented a feature where the user could press a button on the LiveView microdisplay to open a URL if one appears in the tweet. If there is no URL shared in the tweet, ideally I wanted to instead open their preferred Twitter client on their phone showing the tweet so that they could take further action (eg retweet, reply, block).
Several clients (‘official’ Twitter app and Plume) successfully capture ACTION_VIEW intents for any twitter.com URL and will display the tweet as desired. Other clients capture various other intents but don’t appear capable of opening a specific tweet via an intent. In some cases there are other undocumented intents that will allow a user profile to be opened via an intent – this is what WristTweets falls back on for clients that can’t directly open a tweet via an intent.
Since others may find this useful, shared below are the intents I discovered for Tweetdeck, Plume, Seesmic, Hootsuite, Twidroid Pro / Ubersocial, and the ‘official’ Twitter app. As far as I know none of these are officially documented, and they obviously may change without notice in future updates.
