如何调用android中的BroadcastReceiver onReceive方法内的另一个方法？

Question

嗨，我正在使用BroadcastReciever跟踪传入的消息并将消息发送到数据库通过webservices存储。但是每当我在onReceive方法中调用一个方法时，它就会说错误消息unable to start receiver。

package com.android.message.alert; 

import android.app.AlertDialog; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.os.Bundle; 
import android.speech.tts.TextToSpeech; 
import android.telephony.SmsMessage; 
import android.util.Log; 
import android.view.View.OnClickListener; 
import android.widget.Toast; 
import com.webservice.call.SendWebservice; 

public class MessageListener extends BroadcastReceiver 
{ 
    TextToSpeech tts; 
    public static final String ACTION = "android.provider.Telephony.SMS_RECEIVED"; 
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     if(intent!=null && intent.getAction()!=null && ACTION.compareToIgnoreCase(intent.getAction())==0) 
     { 
      Bundle bundle = intent.getExtras(); 
      Object[] pdus = (Object[]) bundle.get("pdus"); 
      final SmsMessage[] message = new SmsMessage[pdus.length]; 
      for (int i = 0; i < pdus.length; i++) 
      { 
       message[i] = SmsMessage.createFromPdu((byte[])pdus[i]); 
      } 
      SendWebservice.sendToWebservice(message[0].getMessageBody()); 
     } 
    } 
} 

任何有关如何调用onReceive方法内的另一个方法的帮助将是有帮助的。请帮我解决这个问题。

我打电话广播reciever Web服务在下面的代码：

public class CheckTechToolsWebServiceReceiver extends BroadcastReceiver { 
    String responsePanelIcon = ""; 
    private Context mContext; 

    @Override 
    public void onReceive(Context context, Intent intent) { 
    /*

    Data.deviceTime = System.currentTimeMillis(); 
    try { 
     new BackGroundTask().execute(context); 
    } catch (Exception e) { 
     // TODO: handle exception 
     e.printStackTrace(); 
    } 
    } 

    private void doFailureSettins() { 
    Data.isWebServiceConnected = false; 
    Data.isInternetConnected = false; 
    Data.PANEL_ICON_STATUS = null; 
    } 

    private class BackGroundTask extends AsyncTask<Context, Context, String> { 
    @Override 
    protected String doInBackground(Context... params) { 
     // TODO Auto-generated method stub 
     callServices(); 
     return null; 
    } 

    @Override 
    protected void onPostExecute(String result) { 
     // TODO Auto-generated method stub 
     super.onPostExecute(result); 
     Iterator<CheckTechToolsServiceAvailaibilityListener> iterator = ConstantLib.WEBSERVICE_STATE_SET 
      .iterator(); 

     while (iterator.hasNext()) { 
     CheckTechToolsServiceAvailaibilityListener webServiceStateListener = iterator 
      .next(); 
     webServiceStateListener 
      .techToolsWebServiceState(Data.isWebServiceConnected);

      JSONObject jsonObject1 = new JSONObject(responseJson); 
      String responseCode = jsonObject1
