                case BluetoothChatService.STATE_CONNECTED:
                    mTitle.setText(R.string.title_connected_to);
                    mTitle.append(mConnectedDeviceName);
                    mConversationArrayAdapter.clear();

                byte[] writeBuf = (byte[]) msg.obj;
                // construct a string from the buffer
                String writeMessage = new String(writeBuf);
                mConversationArrayAdapter.add("Me:  " + writeMessage);

            case MESSAGE_READ:
                byte[] readBuf = (byte[]) msg.obj;
                // construct a string from the valid bytes in the buffer
                String readMessage = new String(readBuf, 0, msg.arg1);
                mConversationArrayAdapter.add(mConnectedDeviceName+":  " + readMessage);
                break;
            case MESSAGE_DEVICE_NAME:
