Consider:

private Handler myHandler= new Handler(){
        @Override
        public void  handleMessage(Message msg){        
            switch(msg.what){
                case 0:
                    this.removeMessages(0);
                    messageSendingCodeWhat0();
                 break;
                default:
                    super.handleMessage(msg);
                    break;
            }
        }
    };
