Question

Hi guys i’m getting the following Exception while readying contact list.

04-13 13:51:15.210: E/AndroidRuntime(7343): java.lang.IllegalStateException: get field slot from row 0 col -1 failed

Here is my getContact function

 public static ContactList getContactList(Context context){
    ContactList contactList = new ContactList(RequestStatus.CONTACT_LIST);
    Cursor people =     context.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, null);
    while(people.moveToNext()) {
       int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
       String contact = people.getString(nameFieldColumnIndex);
       int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER);
       String number = people.getString(numberFieldColumnIndex);  
       contactList.addContact(new Contact(contact,number));
    }
    people.close();
    return contactList;
}

The exception is being thrown at following line.

String number = people.getString(numberFieldColumnIndex); 

what could be wrong?

You can use the below method to get a list of contacts::

private ContactList getDetails(){
    ContactList contactList = new ContactList(RequestStatus.CONTACT_LIST);
    Uri uri = contactsContract.CommonDataKinds.Phone.CONTENT_URI;
    ContentResolver cr = getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
    String[] projection    = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER };
    Cursor names = getContentResolver().query(uri, projection, null, null, null);

    int indexName = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
    int indexNumber = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
    names.moveToFirst();
    do {
        String name   = names.getString(indexName);
        Log.e("Name new:", name);
        String number = names.getString(indexNumber);
        Log.e("Number new:","::"+number);
        contactList.addContact(new Contact(name,number));
    } while (names.moveToNext());
    return contactList;
}
