hi everyone, i'm trying to retrieve my contacts , using ContentResolver.query(..)
the problem is, i have like 5000 contacts, and when running, it runs out of memory, it's working fine though with something like 1000 contacts, what should i do


here is the code for the cursor

final String[] CONTACT_PROJECTION = new String[] { Contacts._ID,
		Contacts.DISPLAY_NAME, };
ContentResolver cr = getContentResolver();

Uri contacts = Contacts.CONTENT_URI;
Cursor cur = cr.query(contacts, CONTACT_PROJECTION, null, null,
		Contacts.DISPLAY_NAME + " ASC");

thanks for ur help
