Android Question add a new calendar to the device's calendar

[SMOOTSARA]

Hey guys ?

I'm going to add a new calendar to the device's calendar database.

I read the following descriptions.

1-https://developer.android.com/guide/topics/providers/calendar-provider#kotlin

2-https://developer.android.com/reference/android/provider/CalendarContract


Finally, I found a way to add a new calendar to the database at this link

3-https://developer.android.com/reference/android/provider/CalendarContract.Calendars


I tried to write these codes with B4A

    Sub Process_Globals
    Dim G_CalendarConstants As CalendarConstants

    Dim G_EventConstants As EventConstants   
    
    Dim G_AttendeesConstants As AttendeesConstants
    Dim G_remindersConstants As RemindersConstants
    Dim G_InstancesConstants As InstancesConstants


    Private ContentResolver1 As ContentResolver



End Sub

and

Sub make_new_calendar

''    https://developer.android.com/reference/android/provider/CalendarContract.Calendars


    Dim ContentValues1 As ContentValues
    ContentValues1.Initialize
    
    
    ContentValues1.PutInteger(G_CalendarConstants.VISIBLE,1)
    ContentValues1.PutString(G_CalendarConstants.ACCOUNT_NAME,"[email protected]")
    ContentValues1.PutString(G_CalendarConstants.ACCOUNT_TYPE,"xxxxx.group")
    ContentValues1.PutString(G_CalendarConstants.NAME,"Persian Calendar")
    ContentValues1.PutString(G_CalendarConstants.CALENDAR_DISPLAY_NAME,"xxxxx Calendar")
    ContentValues1.PutInteger(G_CalendarConstants.CALENDAR_COLOR,-3144201)
    ContentValues1.PutInteger(G_CalendarConstants.CALENDAR_ACCESS_LEVEL,200)
    ContentValues1.PutInteger(G_CalendarConstants.SYNC_EVENTS,1)
    ContentValues1.PutString(G_CalendarConstants.CALENDAR_TIME_ZONE,"Asia/Tehran")
    ContentValues1.PutString(G_CalendarConstants.ALLOWED_REMINDERS,"0,1,2")
    ContentValues1.PutString(G_CalendarConstants.ALLOWED_AVAILABILITY,"0,1")
    ContentValues1.PutString(G_CalendarConstants.ALLOWED_ATTENDEE_TYPES,"0,1,2")
    ContentValues1.PutString(G_CalendarConstants.OWNER_ACCOUNT,"persiancalendar#[email protected]")

    
    Dim resUri As Uri = ContentResolver1.Insert(G_CalendarConstants.CONTENT_URI,ContentValues1)
    Dim calenderID As Int = resUri.ParseId
    Log($"calender id is: ${calenderID}"$)
    
End Sub

But B4A stops the program with an error

We see here that we have to do it with a " sync adapters " !!
Also in link number 3 (operation) we see that we have been told "All operations can be done either as an app or as a sync adapter. "

Please guide me how to use "sync adapters" for inserting a new calendar "

? ? Thanks ? ?

I don´t think that you are allowed to do this.
It may be possible when your app is the DeviceOwner App (Kiosk-Mode). Here you have more rights.

I don´t think that there is a SyncAdapter available in B4A. Never saw one.

Under the Line i suggest to go to https//calendar.google.com/ and create a new Calendar there. Here you have the rights to add new Calendars to your Google Account.

Hello DonManfred
This is a device database and is not just for the Google calendar
This database also includes a phonebook calendar
