I am trying to add an event to android calender my code works fine on older version devices (Android 2.3). But the same code gives the "Only the provider may write to calendar_timezone" error when trying to run in newer android devices(Android 4.1)
Note: I dont want to Use latest calender API to add events , as this apis are available for devices having android builds >=14
Below is the detail log of the error
