Get all contacts and their details (e.g. postal address) in one OUTER JOIN query

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

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.
