[Sugar-devel] Regarding opening one Sugar activity from inside another

[James Cameron]

I'm only speculating, so you'll need to test and evaluate.

launch_bundle does not take arguments for the activity, so Browse
won't know to open the URL.

Perhaps you should do something like this;

1.  create a Journal object in the datastore,

2.  set the metadata mime_type to text/uri-list,

3.  write a single URL to the object,

4.  call launch_bundle passing the uid of the Journal object,

To evaluate my speculation, please review source code;

https://github.com/sugarlabs/browse-activity/blob/master/activity/activity.info#L7
tells Sugar that the Browse activity is capable of opening any Journal
object with the mime_type of text/uri-list.

https://github.com/sugarlabs/browse-activity/blob/master/webactivity.py#L350
shows how the Browse activity will react when read_file reads a
Journal object of that mime_type.

https://developer.sugarlabs.org/sugar3/sugar3.datastore.datastore.html
describes the Journal datastore API for activities.

https://github.com/sugarlabs/sugar/blob/master/src/jarabe/journal/misc.py#L242
shows how the Journal activity can start a Journal object that isn't
an activity bundle.

https://github.com/sugarlabs/get-books-activity/blob/master/GetIABooksActivity.py#L643
shows how the Get Books activity may start Read or Browse given a
selected downloaded book.  Follow the code path down from this point,
and you'll see it call launch_bundle.
