I would say that the way you query your contacts data is wrong.

It looks like you're fetching ALL your contacts with all the contact's data from the database, and then filtering the contacts in a while loop. I would suggest doing this from within the query, something like this (not tested):

Cursor cur = cr.query(
    ContactsContract.Contacts.CONTENT_URI, 
    new String[] { "_ID", "DISPLAY_NAME" },
    "HAS_PHONE_NUMBER = ?", new String[] { "1" }, 
    null);
