Getting an IllegalArgumentException trying to impl

I am trying to create ExtendedProperties for my event and got this error below :

My code below :

ContentValues customerContentValues = new ContentValues();
Uri uriExtendedProperties = Uri.parse("content://com.android.calendar/extendedproperties");
customerContentValues.put(Events._ID,model.mId);
customerContentValues.put("ClientIdname", model.mCustomerName);
customerContentValues.put("RdvType", model.mEventType);
customerContentValues.put("RdvEmplacement", model.mEmplacement);
customerContentValues.put("RdvAdresse", model.mAddresse);
ops.add(ContentProviderOperation.newInsert(uriExtendedProperties).withValues(customerContentValues).build());

Is there anything i've missed ? need some push.. thanks in advance

Is there somebody to tell more about sync adapter beacause i'm really stucked.... any suggestion will be welcomed.

ExtendedProperties is a little different then the ordinary Evnets and Attendees tables.

in order to write to it you will need to modify the uri you are using and adding 'caller_is_syncadapter', 'account_name' and 'account_type' params.

here is an example:

Uri extendedPropUri = ExtendedProperties.CONTENT_URI;
    extendedPropUri = extendedPropUri.buildUpon()
            .appendQueryParameter(CalendarContract.CALLER_IS_SYNCADAPTER,"true")
            .appendQueryParameter(Calendars.ACCOUNT_NAME, this.accountName)
            .appendQueryParameter(Calendars.ACCOUNT_TYPE, this.accountType).build();

and then the insert looks like:

ContentValues extraDataValues = new ContentValues();
extraDataValues.put(ExtendedProperties.EVENT_ID, eventId);
extraDataValues.put(ExtendedProperties.NAME, key);
extraDataValues.put(ExtendedProperties.VALUE, value);

context.getContentResolver().insert(extendedPropUri, extraDataValues);
