Playing with Android and PC

When i run my game with both clients on PC it work's just fine, but when i try with one on Android and another on PC, the strem.ReadNext(); always gives me the error, "Invalid casting type".

if (stream.isWriting)
        {
            // We own this player: send the others our data
            stream.SendNext(_moveRight);
            stream.SendNext(_moveLeft);
            stream.SendNext(_moveUp);
            stream.SendNext(_moveDown);
            stream.SendNext((Vector2)transform.position);
        }
        else
        {
            // Network player, receive data
            _moveRight = (bool)stream.ReceiveNext();
            _moveLeft = (bool)stream.ReceiveNext();
            _moveUp = (bool)stream.ReceiveNext();
            _moveDown = (bool)stream.ReceiveNext();
            _networkPosition = (Vector2)stream.ReceiveNext();

            _networkDistance = Vector2.Distance(_networkPosition, transform.position);
        }
