how do i delete a single calendar from the native calendar app (not only the entries; the whole calendar) without to wipe out the app in android >4.0?
This feature was available till ICS.
In Calendar app, go to
i just ran into the same problem. i have created a local calendar with an app and then removed the app before deleting the calendar. I could re-install the app and delete the calendar there.. so for you as a developer this means you should probably add this functionality to your app anyways..
however if you need a quick fix or if someone else is running into this problem with a third party app that does not provide a way to remove it's own calendars you can use the app iCal Import/Export CalDAV by Lukas Aichbauer as this app allows you to remove any local calendars. just start it, select "Choose Calendar" and select the calendar you want to remove. Then click "Delete Calendar" and confirm if you are certain you have selected the right one :) maybe use the same app first to pull a backup of your calendars you want to keep ;)
