[Android]problem when delete contacts,please help me
- by Enchor
I have been working with Android contacts. I am able to show them, update but
when I want to delete any, it is not deleted completely. In Contacts
application is shown as (Unknown) without any data. Here is my example:
ArrayList ops = new ArrayList();
ops.add(ContentProviderOperation.newDelete(Data.CONTENT_URI)
.withSelection(Data.CONTACT_ID + "=?", new String[]{selectedid})
.build());
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
Should I do anything else to delete contact entirely?
It seems that these code delete info in table ContactsContract.Data but it does not delete element related in table ContactsContract.Contacts or ContactsContract.RawContacts.how can i do to delete an contact completely?
============================================================================
also, i tried deprecated method. It dose work, but i do not want to do so. Here is the sample code:
ContentResolver contentResolver = m_cContent.getContentResolver();
contentResolver.delete(People.CONTENT_URI, People.NAME + "=?", new String[] { SelectedName });
and if i modify this code to
ContentResolver contentResolver = m_cContent.getContentResolver();
contentResolver.delete(ContactsContract.Contacts, ContactsContract.Contacts._ID + "=?", new String[] { Selectedid });
It has no effect.
Does it mean that one can only delete a contact by name instead of by its id?
What on earth can i do to delete contact?
Thanks,
