Ex:intent with variables not working

We are developing an application to return photos and text strings back to Collect to populate multiple fields, following the documentation https://docs.getodk.org/launch-apps-from-collect/. For this external application to work properly, we need to pass some data to it from collect, which is from a user input. But when I set the intent call to:


Collect returns an error "Could not evaluate '${text1}'"

If I put a constant there, it works properly. For example: ex:com.my.externalapp(value='command',customtext='My constant text') works very well. So I think I'm making some mistake with the syntax, what would be the right way to do this?

Unfortunately, not so many people have experience working with external apps. Please let us know if you figure this out!

I wish this would work as with others. Has anybody found out a solution to this? @amalm

If it could help I found out that doing this (i.e. putting quotes around the variable)


will push a random value like 'aw98w211we/text1'. Does this mean anything?

If you refer to another question it should not contain quotes so definitely the expression should be like:

could you attach your form? because I guess there is something wrong there.
