Hi all,
I am very new to ODK, so i do apologize if some of this are elementary questions. From what i have been able to understand from wikis, github and old posts here is what i have understood so far:
Here is my question. In ODK Collect world, the collect app uses javarosa code to parse XML on the client and do things like constraint enforcement. What is the equivalent in ODK Survey ? I am looking in ODK Survey code, as well as in androidcommon and androidlibrary. Is the JSON parsing, validation part of one of these modules ? I will continue digging into the code but would appreciate some pointers.
Thanks
-Giri
Apologies for double post. There was some eventual consistency with google
groups with my first post (did not show up) and i thought it failed. Sorry
did not mean to spam.

In ODK Survey, a lot of the functionality that you are looking for exists
in the JavaScript code. The repo that you will want to look at is the
App-Designer (https://github.com/opendatakit/app-designer). The code
responsible for generating the formDef.json that Survey uses can be found
at
https://github.com/opendatakit/app-designer/blob/master/xlsxconverter/XLSXConverter2.js.
Survey then uses the formDef.json to render and navigate through the form.
In terms of where to look for the code that does the validation for most
prompts, that can be found at
https://github.com/opendatakit/app-designer/blob/master/app/system/survey/js/prompts.js.
The function that you will want to take a look at is _isValid(isStrict).

Hi Clarice
Thanks so much for quick response. One more thing. Are you saying that ODK
Survey android code base actually does the formDef.json parsing and
validation (say against constraints) in javascript ? Reason i ask is that i
do not find any js code in https://github.com/opendatakit/survey ?

Yes, we use an Android WebView to render and parse the formDef.json. The
actual JavaScript code is bundled into the Survey APK via two different zip
files (configzip and sytemzip) which can be found at
https://github.com/opendatakit/survey/tree/master/survey_app/src/main/res/raw.
