programmatically unset a default application
<p>I made a Home application and I'd like to offer the ability to exit it and unset it as the default application.  </p>

<p>Exit is easy (just starting an intent) but the problem is I don't want my program to be launched again the next time the user click the Home button.</p>

<p>I know that this can be done by going in the <em>parameters / Applications / my app / erase default actions</em> but I would like to do it from my program so that the user doesn't have to search this function.  </p>

<p>How can it be done ?  </p>
