I am using the sample code from the Google tutorial. The projection is where I specify the data I want to collect. How do I specify that I want the phone numbers? The sample from Google does not get phone number. But I want to obtain the phone number, so I add the field for Phone.NUMBER
. But when I do, the app always crashes. Here is my projection.
// The projection for the CursorLoader query. This is a list of columns that the Contacts
// Provider should return in the Cursor.
@SuppressLint("InlinedApi")
final static String[] PROJECTION = {
// The contact's row id
Contacts._ID,
// A pointer to the contact that is guaranteed to be more permanent than _ID. Given
// a contact's current _ID value and LOOKUP_KEY, the Contacts Provider can generate
// a "permanent" contact URI.
Contacts.LOOKUP_KEY,
// In platform version 3.0 and later, the Contacts table contains
// DISPLAY_NAME_PRIMARY, which either contains the contact's displayable name or
// some other useful identifier such as an email address. This column isn't
// available in earlier versions of Android, so you must use Contacts.DISPLAY_NAME
// instead.
Utils.hasHoneycomb() ? Contacts.DISPLAY_NAME_PRIMARY : Contacts.DISPLAY_NAME,
// In Android 3.0 and later, the thumbnail image is pointed to by
// PHOTO_THUMBNAIL_URI. In earlier versions, there is no direct pointer; instead,
// you generate the pointer from the contact's ID value and constants defined in
// android.provider.ContactsContract.Contacts.
Utils.hasHoneycomb() ? Contacts.PHOTO_THUMBNAIL_URI : Contacts._ID,
// The sort order column for the returned Cursor, used by the AlphabetIndexer
SORT_ORDER,
// Contacts.HAS_PHONE_NUMBER,
//
CommonDataKinds.Phone.NUMBER,
};
// The query column numbers which map to each value in the projection
final static int ID = 0;
final static int LOOKUP_KEY = 1;
final static int DISPLAY_NAME = 2;
final static int PHOTO_THUMBNAIL_DATA = 3;
final static int SORT_KEY = 4;
// final static int HAS_PHONE_NUMBER = 5;
final static int PHONE_NUMBER = 5;
}
