Chat list update problem

[TazmanOne]

After sending some people text message, application redirect to WhatsApp?
Chat list is not updated, still old dialogs, but if I open dialog i saw last sended messages.
How get updated chat list?
Can we send message from non-contact list people?

string phonenumber="123456789";
WContact contact = new WContact(phonenumber+"@s.whatsapp.net", phonenumber+"@s.whatsapp.net");

WhatsappApi.getInstance().sendMessage(contact, message, this, new SendMessageListener() {

Create a contact type WContact . and pass this contact to sendMessage function
