Default Need help retrieving Contact phone numbers

In Chapter 7, Databases and Content Providers (p.241) Listing 7-19, Accessing the contact Content Provider, the example given to extract the phone number does not work. Instead, this code extracts the contact name and the corresponding contact ID. I haven't been able to figure out how to display the phone number:

Obtain a cursor for every aggregated contact

Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
// Let the Activity manage the cursor life cycle
int nameIndex = people.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME);
int contactIndex = people.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone._ID);

if(people.moveToFirst()) {
	do {
		// Extract the phone number
	      String phone = people.getString(contactIndex);
              String name = people.getString(nameIndex);
	      Toast.makeText(SampleProvider.this, name + ": " + phone,  Toast.LENGTH_SHORT).show();		
	} while(people.moveToNext());
