I also meet the similar problem with
Contacts.ContactMethods.CONTENT_EMAIL_URI, but it works fine with
Contacts.ContactMethods.CONTENT_URI. My code is:
Uri uri = Contacts.ContactMethods.CONTENT_URI;
String selection = Contacts.ContactMethods.KIND + "=" +
Contacts.ContactMethods.EMAIL_KIND
Cursor c = this.getContentResolver().query(uri, EMAIL_PROJECTION, selection,
null, null);
