Android Contact phone number using Loader Invalid column data1

Question

I used to use content resolver previously to fetch Contact list and their details while that still works I wanted to try the Loader method which queries the Content Provider

Answer 1

This is an excerpt of what I actually do in my (working) code.

These are my relevant imports:

import android.provider.ContactsContract;
import android.provider.ContactsContract.CommonDataKinds.Email;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.provider.ContactsContract.Contacts;

Given that id is a string (representing a number, like "1", "20", ...)

// Query for phone numbers for the selected contact id
final Cursor cur = getContentResolver().query
    (
    Phone.CONTENT_URI, null,
    Phone.CONTACT_ID + "=?",
    new String[] {id}, null
    );

final int phoneIdx = cur.getColumnIndex(Phone.NUMBER);
final int phoneType = cur.getColumnIndex(Phone.TYPE);

// ...

    if(cur.moveToFirst())
    {
        final String name =
            cur.getString
            (
                cur.getColumnIndexOrThrow
                (
                    ContactsContract.Contacts.DISPLAY_NAME
                )
            );
    }

Hope it puts you on the right path
