Answer 1

this is real example
public Cursor getAllContacts() {
            Uri uri = ContactsContract.Contacts.CONTENT_URI;
            String[] projection = new String[] {
                    ContactsContract.Contacts._ID,
                    ContactsContract.Contacts.LOOKUP_KEY,
                    ContactsContract.Contacts.DISPLAY_NAME, 
                    ContactsContract.Contacts.DISPLAY_NAME_ALTERNATIVE
            };
            String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '1'";
            String[] selectionArgs = null;
            String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

            return getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);
        }
