Linking ODK collect to custom android app WITH pre_populated fields

I have developed an android app which is able to open ODK form.

I have a field within ODK form called pid.

Now am struggling on how I can get "pid value"from my app and pre populate it to ODK form once the form is open.

Hi @samiek
welcome to the forum! Please introduce yourself here!

You would need to implement changes in ODK Collect to handle such values because it's not possible using the original version.
