Answer 1

try this

Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 

while (cursor.moveToNext()) {
    String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
    String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
    System.out.println(contactId + "   " + name);
}
cursor.close();

it returns the contact's name and the id (the id is probably the row number of the contacts table)
