Cursor cur = cr.query(ContactsCont         


        

Answer 1

One can read out all the users' birthday with the following code:

ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0) {
    while (cur.moveToNext()) {
        String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
        String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
        ContentResolver bd = getContentResolver();
        Cursor bdc = bd.query(android.provider.ContactsContract.Data.CONTENT_URI, new String[] { Event.DATA }, android.provider.ContactsContract.Data.CONTACT_ID+" = "+id+" AND "+Data.MIMETYPE+" = '"+Event.CONTENT_ITEM_TYPE+"' AND "+Event.TYPE+" = "+Event.TYPE_BIRTHDAY, null, android.provider.ContactsContract.Data.DISPLAY_NAME);
        if (bdc.getCount() > 0) {
            while (bdc.moveToNext()) {
                String birthday = bdc.getString(0);
                // now "id" is the user's unique ID, "name" is his full name and "birthday" is the date and time of his birth
            }
        }
    }
}
cur.close();

But is there any better or shorter way to do it?
