I basically want a design where whenever my Android App modifies the backend database on Kinvey, one other pre defined device with a known IP gets a trigger that new data is available and the device should initiate a fetch on the updated database. 

Junaid:

This should be possible using Kinvey business logic. I would recommend checking out the business logic reference, and reading up on onPostSave(request, response, modules)

You can check out that document over here: http://devcenter.kinvey.com/android/reference/business-logic/reference.html  Business logic is based on Javascript so it should be pretty easy to pick up if you have any experience in that realm.

Thanks,
