Hmm...I don't really like that we have to muck with the intent after getting
this to make it work.

Maybe we can see about only doing the conversion from the bitmap to a file in
the background thread and rework some signatures to make that work?

Then you could change it to take a screenshotFile in this method signature and
add the extra if it's not null.

Done.
