<div dir="ltr"><div><div><div><div>Hi James, </div>I do not think that these dependencies should be encoded. I do not want to create a confusing nested activity list thingo. </div>When I think about it a little more, it kind of splits in to 2 use cases for me. Specific (launch this given bundle; eg. open pippy after python export in turtle) and abstract (launch a bundle to open/create something with a mime; eg. open downloads in browse). For apps that are using it specifically they might benefit from having the activity installed before time, but I think a popup works and is simple. They also may never use the activity they request or the user may already have the activity installed. For activities that use it abstractly, I think they gain no benefit form installing something before usage or when the user needs it. </div>Thanks, </div>Sam </div> <div class="gmail_quote">On Mon, Apr 20, 2015 at 2:10 PM James Cameron <<a href="mailto:quozl@laptop.org">quozl@laptop.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I have no use case for the feature, sorry. The activities I'm mostly concerned with stand alone. But if an activity is written to use the feature, a dependency is created; my question is _will_ it be encoded, and what are the effects on other actions that change the list of activities? What you describe as non-essential is a type of dependency. Do you have a use case for that?
