Hi, iam trying to publish my app in google store for first time. Which things do i need to modify in config.xml. For example are there any naming conventions for widget id? And what else is needed to be changed?
That value is your app id and cannot be changed at a later date. I would strongly suggest looking at this page: https://cordova.apache.org/docs/en/latest/config_ref/index.html to make sure you have your app configured how you want it.
