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

In my case the problem was with URI.

I was using this:

Uri uri = ContactsContract.Contacts.CONTENT_URI;

and I changed for this (Phone.CONTENT_URI) to resolve the problem and obtain the phone number:

Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;

This is the rest of the code:

contactos = (TextView) findViewById(R.id.contactos);

Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;

String [] projection = new String[] {
                ContactsContract.Contacts._ID,
                ContactsContract.Contacts.DISPLAY_NAME,
                ContactsContract.CommonDataKinds.Phone.NUMBER
        };

Cursor cursor = getContentResolver().query(uri, projection, null, null, null);

while (cursor.moveToNext()){
            String nombre = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
            String telefono = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            contactos.append("Name: ");
            contactos.append(nombre);
            contactos.append(" - Phone Number: ");
            contactos.append(telefono);
            contactos.append("\n");
        }
