title: How can i know supported intents of the 3rd party app
body: <p>I've built an app called xLancer (<a href="https://market.android.com/details?id=kz.jay.xlancer.activity" rel="nofollow">https://market.android.com/details?id=kz.jay.xlancer.activity</a>) that retrieves job listings from Elance. Now i want to implement a feature that would remind me to bid on a project at a later time. Instead of reinventing the wheel i want to launch any external TODO/Task manager app. But now i am stuck, i don't know which URI or action should be specified, so far i've only used intents to call my internal activities by specifying class name explicitly.</p>
  
  <p>So the question is: how can i know which URI/action should be specified?</p>
