Question

I know how to retrieve contact data for specific contacts. However, i can\'t find a way to get all contacts plus some of their details in a single query. The following code

Answer 1

if You have a contact ID and you want to fetch the Postal Address then use this :

         Uri postal_uri = ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI;
         Cursor postal_cursor  = getContentResolver().query(postal_uri,null,  ContactsContract.Data.CONTACT_ID + "="+contactId.toString(), null,null);
          while(postal_cursor.moveToNext())
            {
             String Strt = postal_cursor.getString(postal_cursor.getColumnIndex(StructuredPostal.STREET));
             String Cty = postal_cursor.getString(postal_cursor.getColumnIndex(StructuredPostal.CITY));
             String cntry = postal_cursor.getString(postal_cursor.getColumnIndex(StructuredPostal.COUNTRY));
            } 
            postal_cursor.close();                   

Answer 2

All contact information in Android 2.0 is stored in a single database table. So you can get all the information you need in a single query:

Cursor c = getContentResolver().query(ContactsContract.Data.CONTENT_URI,
    null, null, null, sortOrder);

The just iterate through the data and check Data.MIMETYPE column. For example, if this column has StructuredPostal.CONTENT_ITEM_TYPE value, then you can get StructuredPostal fields from this column.
