Adding Reminders in Android
I am new to android and I am developing an app to add a remainder on a button click. I have gone through Programmatically add reminder in android calendar? and Reminder Functionality. But the app crashes with an SQLite Exception Error, when I run in my emulator(Marshmallow). I couldnt understand what changes are made in Marshmallow regarding Calendar API. Would like to know the reason for the exception. Stack Trace:

android.database.sqlite.SQLiteException
There is no problem in your code
Above is happening due to your emulator does not have any account(google) sync/signed in it. As from marshmallow and above i have seen if your calendar does have any account in it. Above exception will occur. You cannot do anything of it.
