Question

我正在尝试定期向我的服务器发送电池信息。我已经测试了网络服务代码，它在没有使用Android服务的情况下正常工作但在我尝试在服务中的runnable中调用webservice方法时抛出异常。

当我尝试在我的Android服务中运行可运行的Toast时，它的工作正常。

 package com.services;

    import org.ksoap2.SoapEnvelope;
    import org.ksoap2.serialization.SoapObject;
    import org.ksoap2.serialization.SoapPrimitive;
    import org.ksoap2.serialization.SoapSerializationEnvelope;

    import android.widget.Toast;

    public class BackService extends Service {
        private int m_interval = 20000; // 5 seconds by default, can be changed later
        private Handler m_handler;
        int  Level;

         private static final String SOAP_ACTION = "http://xy.xy/insertfeedback";
            private static final String METHOD_NAME = "insertfeedback";
            private static final String NAMESPACE = "http://xy.xy/";
            private static final String URL = "http://192.168.9.2:8080/WebApplication2/NewWebServiceService?WSDL";

             Toast.makeText(getApplicationContext(), "Service Created", Toast.LENGTH_SHORT).show();
             request= new SoapObject(NAMESPACE, METHOD_NAME);       
             envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
             ht = new HttpTransportSE(URL);
       }

       @Override
       public void onDestroy() {

       }

       @Override

         m_handler = new Handler();
         m_statusChecker.run();
       }

       Runnable m_statusChecker = new Runnable()
       {
            @Override
            public void run() {
                Toast.makeText(getApplicationContext(), ""+ Level, Toast.LENGTH_SHORT).show();
                BatteryService();
                 //updateStatus(); //this function can change value of m_interval.
                 m_handler.postDelayed(m_statusChecker, m_interval);
            }
       };

            Level = intent.getIntExtra("level", 0);
             //Toast.makeText(getApplicationContext(), ""+Level+"%", Toast.LENGTH_SHORT).show();

           }
           };


          public void BatteryService()
          {

              request.addPropertyIfValue("value",50);
              envelope.setOutputSoapObject(request);


              try
              {
                  ht.call(SOAP_ACTION, envelope);
                  final  SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
                  final String str = response.toString();
                  Toast.makeText(getApplicationContext(), str, Toast.LENGTH_LONG).show();
              }
               catch (Exception e) {
                   Toast.makeText(getApplicationContext(),"Exception", Toast.LENGTH_LONG).show();

              }
          }
    }
