android - Delete a single phone type number from a contact -


when 1 of contact have multiple numbers, example:

display name: guesswho
type = home
number = homenumber
type = mobile
number = mobilenumber
type = other
number = othernumber ...

in conclusion ... 1 those.

how can remove type number contact ( let's "mobile" )? have update using userid acquired previous query, or how? need delete single type number, other field of contact must remain intact.

i using piece of code obtaining contact :

int indexname = c.getcolumnindex(contactscontract.commondatakinds.phone.display_name);     int indexnumber = c             .getcolumnindex(contactscontract.commondatakinds.phone.number);     int indextype = c.getcolumnindex(contactscontract.commondatakinds.phone.type);     int indexid = c.getcolumnindex(contactscontract.commondatakinds.phone._id);  string name = c.getstring(indexname);         string number = c.getstring(indexnumber);         string type = c.getstring(indextype);          string typestored = (string) phone.gettypelabel(mcontext.getresources(), integer.parseint(type), "");         log.i("type readed : ", typestored);         string id = c.getstring(indexid);

where c cursor of query.

each number same contact has it's own id. should use deleting. need contact id. can using line of code:

contactid = cursor.getint(cursor.getcolumnindex(contactscontract.commondatakinds.phone.contact_id));

then delete number using following code:

cursor cur = contentresolver.query(rawcontacts.content_uri,              new string[]{rawcontacts._id},             rawcontacts.contact_id + "=?",              new string[] {contactid.tostring()}, null);     int rowid=0;;     if(cur.movetofirst()){         rowid = cur.getint(cur.getcolumnindex(rawcontacts._id));     }      arraylist<contentprovideroperation> ops = new arraylist<contentprovideroperation>();     string selectphone = data.raw_contact_id + " = ? , " +                           data.mimetype + " = ? , " +                           phone._id + " = ?";     string[] phoneargs = new string[] { integer.tostring(rowid),                                          phone.content_item_type,                                          id.tostring()};      ops.add(contentprovideroperation.newdelete(data.content_uri)             .withselection(selectphone, phoneargs).build());     try {         contentresolver.applybatch(contactscontract.authority, ops);     } catch (remoteexception e) {         e.printstacktrace();     } catch (operationapplicationexception e) {         e.printstacktrace();     }
