Cool. I like that Intent way. It is very close to the args way or environment variables.
I keep forgetting about the Delayed Sub starting the activity too. For some reason I think of that as starting the Activity, Executing the Sub, then exiting/pausing the Activity when in reality it keeps it open...and I thought it didn't call the sub until control reverted back to the Activity (Reading again now I guess that only applied to when it was in the background/a service). Either way could be useful depending on what needs done I guess.
