Can we get a string from a third party App silently?

Hi All!

I have looked at getting data from a third party app here:
http://opendatakit.org/help/form-design/examples/#string_3rd_party

This is almost exactly what our client needs. It works wonderfully, except
for a small thing. It currently shows a button on the form. Only when the
button is clicked, is the given intent called.

Is there a way to get the data without showing the button on the screen?
Can we silently get the string from the third party App?

Not without a code change. The button was originally added because the app
didn't have the original value of the field, so it would otherwise
continually get a new value. Also, if you are using the app to do things
like capture blood pressure readings, it would clearly not be a good idea
to always get new data, as any review of the entered form data would
confound things.

The code change is fairly simple. In addition to the "ex:..." appearance
attribute, we could recognize an "ex-immediate:..." appearance attribute
that would invoke the 'onClick' action of the button when the widget is
created (with special handling here to detect when the widget is being
re-created after returning from the 3rd party app, and to not (re)invoke
the 3rd party app in that instance).

I would just have this be a modification in the behavior of these Ex...
widgets.

Code contributions are welcomed.
