[Sugar-devel] [Feature] Start an activity from another activity

[Sam P.]

Hi James,

I do not think that these dependencies should be encoded.  I do not want to
create a confusing nested activity list thingo.

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.

Thanks,
Sam
