Accessing contact' email addresses

Hi!

I'm developing an application in which I need to display user a list of contacts and their email addresses so that user can choose one of them.
I've got some help from Internet and I'm able to display a list of contacts and their number by the following code:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public class ShowContacts extends ExpandableListActivity implements OnChildClickListener {
    private int mGroupIdColumnIndex; 
    
    private String mPhoneNumberProjection[] = new String[] {
            People.Phones._ID, People.NUMBER // CHANGE HERE
    };
 
    
    private ExpandableListAdapter mAdapter;
    
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
 
        // Query for people
        Cursor groupCursor = managedQuery(People.CONTENT_URI,
                new String[] {People._ID, People.NAME}, null, null, null);
 
        // Cache the ID column index
        mGroupIdColumnIndex = groupCursor.getColumnIndexOrThrow(People._ID);
 
        // Set up our adapter
        mAdapter = new MyExpandableListAdapter(groupCursor,
                this,
                android.R.layout.simple_expandable_list_item_1,
                android.R.layout.simple_expandable_list_item_1,
                new String[] {People.NAME}, // Name for group layouts
                new int[] {android.R.id.text1},
                new String[] {People.NUMBER}, // AND CHANGE HERE
                new int[] {android.R.id.text1});
        setListAdapter(mAdapter);
    }
 
    public class MyExpandableListAdapter extends SimpleCursorTreeAdapter {
 
        public MyExpandableListAdapter(Cursor cursor, Context context, int groupLayout,
                int childLayout, String[] groupFrom, int[] groupTo, String[] childrenFrom,
                int[] childrenTo) {
            super(context, cursor, groupLayout, groupFrom, groupTo, childLayout, childrenFrom,
                    childrenTo);
        }
 
        @Override
        protected Cursor getChildrenCursor(Cursor groupCursor) {
            // Given the group, we return a cursor for all the children within that group 
 
            // Return a cursor that points to this contact's phone numbers
            Uri.Builder builder = People.CONTENT_URI.buildUpon();
            ContentUris.appendId(builder, groupCursor.getLong(mGroupIdColumnIndex));
            builder.appendEncodedPath(People.Phones.CONTENT_DIRECTORY);
            Uri phoneNumbersUri = builder.build();
 
            return managedQuery(phoneNumbersUri, mPhoneNumberProjection, null, null, null);
        }
    }
    
    @Override
        public boolean onChildClick(android.widget.ExpandableListView parent,
                        View v, int groupPosition, int childPosition, long id) {
                AlertDialog dialog = new AlertDialog.Builder(ShowContacts.this)
                                .setMessage(((TextView) v).getText().toString())
                                .setPositiveButton("OK", null).create();
                dialog.show();
                return true;
        }
}

What I need now is how to replace numbers by email addresses. What I need to change is People.NUMBER at a couple of places but I'm not able to find any replacement. There is a field called People.PRIMARY_EMAIL_ID but that returns the ID of the email rather than the actuall email.

Kindly guide me what am I missing.

Big thanks in advance!!!
