case 5:
try {
                   outStream = btSocket.getOutputStream();                  } catch (IOException e) {
                     
                  }
                  //message = ExternValues.myphoneid + "5";
                 message = "5";
                 msgBuffer = message.getBytes();                  try {
                   outStream.write(msgBuffer);
                   DisplayToast("正在发送flag为5");
                   outStream.flush();
                    flag = 0;
                  } catch (IOException e) {
                   flag = 0; 
                  }
                  break;  
分步调试的时候到outStream的地方就卡住了,没有发送出去。一直不往下运行,不知道是为什么,跪求大神回答
