Question

Answer 1

Whenever user assign email_id then android create a calendar with Email.So if above solution not turning out for you then you can try this as hack. Find Email associated with Calendar. Hope this will help.

    public String getCalendarIdAndEmail(Context c) {

    String projection[] = {"_id", "calendar_displayName"};
    //   Uri calendars = Uri.parse("content://com.android.calendar/calendars");
    String calID = null;
    try {
        ContentResolver contentResolver = c.getContentResolver();

        if (ActivityCompat.checkSelfPermission(context, Manifest.permission.READ_CALENDAR) != PackageManager.PERMISSION_GRANTED) {
            return calID;
        }
        Cursor managedCursor = contentResolver.query(CalendarContract.Calendars.CONTENT_URI, projection, CalendarContract.Calendars.VISIBLE + " = 1 AND " + CalendarContract.Calendars.IS_PRIMARY + "=1", null, CalendarContract.Calendars._ID + " ASC");
        if (managedCursor.getCount() <= 0) {
            managedCursor = contentResolver.query(CalendarContract.Calendars.CONTENT_URI, projection, CalendarContract.Calendars.VISIBLE + " = 1", null, CalendarContract.Calendars._ID + " ASC");
        } else {
            Log.d("getCount", "" + managedCursor.getCount());
        }

        if (managedCursor.moveToFirst()) {

            int nameCol = managedCursor.getColumnIndex(projection[1]);
            int idCol = managedCursor.getColumnIndex(projection[0]);
            do {
               String calName = managedCursor.getString(nameCol);
                calID = managedCursor.getString(idCol);
                //CalName is Email id you are looking for
                Log.e("tag", "calName " + calName + "____calId " + calID);

            } while (managedCursor.hasNext());//managedCursor.moveToNext());
            managedCursor.close();
        }
    } catch (Exception e) {
        Log.e("error", e.getMessage(););
    }
    return calID;
}
