我正在尝试定期将电池信息发送到我的服务器。我已经测试了 web 服务代码，它在不使用 Android 服务的情况下工作正常，但是当我尝试在服务中的可运行内调用 web 服务方法时抛出异常。

虽然当我尝试在我的 Android 服务中运行可运行的 Toast 时它工作正常。 

 package com.services;

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

    import android.app.Service;
    import android.content.BroadcastReceiver;
    import android.content.Context;
    import android.content.Intent;
    import android.content.IntentFilter;
    import android.os.Handler;
    import android.os.IBinder;
    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";
            SoapObject request;
            SoapSerializationEnvelope envelope;
            HttpTransportSE ht;

       @Override
       public IBinder onBind(Intent intent) {
          return null;
       }

       @Override
       public void onCreate() {

             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() {
          //code to execute when the service is shutting down
       }

       @Override
       public void onStart(Intent intent, int startid) {
             registerReceiver(this.mBatInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));

         Toast.makeText(getApplicationContext(), "Service Stared", Toast.LENGTH_SHORT).show();
         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);
            }
       };


       private final BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver(){

            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();

              }
          }
    }
