I'm guessing there isn't an easy solution to this, but thought I would
throw it out there just in case.
We are launching a system whereby collected samples are labelled in a very
specific, but sequential manner (for the purposes of explanation, assume
the numbering goes 1 2 3 etc). To generate the label, we created a small
3rd party app that is launched from Collect. Because data can not be passed
from Collect to the app we wanted to ensure that users couldn't get one
number and then accidentally trigger the app again and get a second number.
To prevent this happening, the app will only issue a new id once 5 mins has
elapsed - this ensures they can't accidentally trigger the app twice in
quick succession and end up with e.g. number 8 rather than number 7.
However I also wanted to ensure that in case they go back in the form (ie
after 5 mins has elapsed) the app launcher would not be visible. I
therefore set it to be relevant only if another later question was empty.
The flow therefore looks like this:
Label generation question - Only relevant if result is empty
Calculate field to combine other fields and label generation question
Note field to show the label that should be recorded on the sample
Result - Result of sample
This all works perfectly well, however as soon as one answers the result
question (4), the label generation question (1) field is deemed not
relevent and the id is lost, meaning that the note field (3) loses part of
its value. Has anyone got any suggestions for how I might get round this?
Attached is a small example of the form...
If you can build a custom ODK Collect, I just modified the 3rd party app
widgets so that they include a "value" extra that specifies the current
value of the field. This should solve your problem.
The change has been pushed up to the repository. It will be in the next ODK
Collect update (no ETA on that).

Thanks for your response. I'm afraid I am not an android developer so i
can't roll a custom ODK. Fortunately I know some people who can, but
they aren't so familiar with the ODK Collect source code. Apologies if
these are stupid questions, but...
What code is needed in the .xml to pass the value to the 3rd party app?
Thanks so much for committing the change!
Cheers

There is no XML change. The current value of the field is simply passed to
the 3rd party app in the 'vallue' extra. It will either be null (no value)
or have a value (i.e., a String, Integer or Double).

I have downloaded ODK Collect project (zip from repository) its loaded in the eclipse, can you guide where to make changes from 3rd party app communication with ODK collect, any guidance on this would be really helpful.
which is an App that can be invoked from Collect. The breathTest.xml in
that repository is an example form demonstrating how to launch this app
from within Collect.
There are no modifications necessary to ODK Collect itself, unless you want
to pass additional arguments to that app.
