[android-developers] Comms with Intent

Hi all,

I launch an Intent from a servlet once a request for it comes in. The
Intent launches
a SnapPic activity that puts the phone into a preview mode and then
snaps
a pic and send it back to the requester. This works fine - I am now
truing to keep
the phone in the preview mode (I don't call the finish()) on the
activity and for
any subsequent requests I am trying to snap more pictures. Can calls
to methods
of the launched Activity be made from the servlet? In other words, how
can one
app communicate with an activity that it launches? I think this is a
matter of
communicating threads so I am wondering if there's an alternative way
to approach
this problem.

Thanks
