           if(groupid== null)                  groupid = getgroupid(ctx);           arraylist<contentprovideroperation> ops = new arraylist<contentprovideroperation>();           ops.add(contentprovideroperation.newinsert(contactscontract.rawcontacts.content_uri)                 .withvalue(contactscontract.rawcontacts.account_type, null)                 .withvalue(contactscontract.rawcontacts.account_name, null)                 .build());

i have tried not putting number @ all, putting null , putting empty string , still same.

we tried using different dialler , works ok.

is problem dialler or missing field should setting?

the right way not add number. adding null or empty string lead same crash.

also, since doing new insert not update existing contact. need newupdate that.
