I want to use OpenIntents.org intents in my applications. How can I ensure that the receiving application is installed on the user's phone?
<p>It looks like <a href="http://openintents.org" rel="nofollow">http://openintents.org</a> has a lot of promise and could save me a lot of wheel reinventing.</p>

<p>When using openintents in my Android apps, how can I make sure that the appropriate openintents apps are installed to receive those intents?</p>

<p>For example, there is an open intent for a file picker: <a href="http://www.openintents.org/en/node/164" rel="nofollow">http://www.openintents.org/en/node/164</a>,
if I use this, or another intent like it, how can I be sure everything will work? (Please note that i'm interested in the general use of open intents, and not in file choosing strategies.)</p>

<p>I'd really like to be able to use these in my apps because it would save tremendous amounts of time. Thanks for looking.</p>
