电信SDK Pay函数里面System.out.print 无输出消息

private void Pay(HashMap<String, String> payParams){

            System.out.print("----------Pay DianXin----------"); // 勿使用 这个函数进行调试 输出不了消息。
            UnityPlayer.UnitySendMessage(m_GameObject,"Message","Pay DianXin......");

            EgamePay.pay(m_Context,payParams,new EgamePayListener() {
                @Override
                public void paySuccess(Map<String, String> params) {


                  System.out.println("Prop--"+params.get(EgamePay.PAY_PARAMS_KEY_TOOLS_DESC)+"--success");
                  // params.get(EgamePay.PAY_PARAMS_KEY_TOOLS_DESC) 返回的是道具名称如:金币X6000
                  Log.d("Unity3D", "Prop-Log-"+params.get(EgamePay.PAY_PARAMS_KEY_TOOLS_DESC)+"--success");

                  UnityPlayer.UnitySendMessage(m_GameObject,"OnPaySuccess","Prop-Unity-"+params.get(EgamePay.PAY_PARAMS_KEY_TOOLS_DESC)+"--success");

                }

                @Override
                public void payFailed(Map<String, String> params, int errorInt) {

                    System.out.println("Prop--"+params.get(EgamePay.PAY_PARAMS_KEY_TOOLS_DESC)+"--faild,code="+errorInt);

                    Log.d("Unity3D", "Prop-Log-"+params.get(EgamePay.PAY_PARAMS_KEY_TOOLS_DESC)+"--faild,code="+errorInt);

                    UnityPlayer.UnitySendMessage(m_GameObject,"OnPayFaild","Prop-Unity-"+params.get(EgamePay.PAY_PARAMS_KEY_TOOLS_DESC)+"--faild,code="+errorInt);
                }

                @Override
                public void payCancel(Map<String, String> params) {

                    System.out.println("Prop--"+params.get(EgamePay.PAY_PARAMS_KEY_TOOLS_DESC)+"--cancel");

                    Log.d("Unity3D", "Prop-Log-"+params.get(EgamePay.PAY_PARAMS_KEY_TOOLS_DESC)+"--cancel");

                    UnityPlayer.UnitySendMessage(m_GameObject,"OnPayCancel","Prop-Unity-"+params.get(EgamePay.PAY_PARAMS_KEY_TOOLS_DESC)+"--cancel");
                }
            });
        }
