无法启动接收器NullPointerException

我有一个BroadcastReceiver接收短信，然后应该立即发送回复短信，如果文本有某些字符。现在它收到并发送短信，但它很快强制关闭给出类似如下：无法启动接收器... NullPointerException ... LogCat中的ActivityThread.handleReciever（释义）...可能是什么问题？这里是我的代码，你要寻找的ELSE IF语句（这是我目前测试的部分）：无法启动接收器NullPointerException

public class Service extends BroadcastReceiver { 

@Override 
public void onReceive(Context context, Intent intent) { 
    // TODO Auto-generated method stub 

    if (intent.getAction() 
      .equals("android.provider.Telephony.SMS_RECEIVED")) { 
     Bundle bundle = intent.getExtras(); 
     SmsMessage[] msgs = null; 
     String msgFrom; 
     if (bundle != null) { 
      try { 
       Object[] pdus = (Object[]) bundle.get("pdus"); 
       msgs = new SmsMessage[pdus.length]; 
       for (int i = 0; i < msgs.length; i++) { 
        String verificationCode = "717345221"; 
        msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]); 
        msgFrom = msgs[i].getOriginatingAddress(); 
        String encodeHash = Uri.encode("#"); 
        msgFrom = "0" + msgFrom.substring(4) + encodeHash; 
        String msgBody = msgs[i].getMessageBody(); 

        if (msgBody.startsWith(verificationCode)) { 
         this.abortBroadcast(); 
         msgBody = msgBody.substring(verificationCode 
           .length()); 
         try { 
          String dial = msgBody + "*" + msgFrom; 
          Intent call = new Intent(Intent.ACTION_CALL, 
            Uri.parse("tel:" + dial)); 
          call.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
          context.startActivity(call); 

         } catch (Exception e) { 
          e.toString(); 
         } 
        } else if (msgBody.contains("TEST123")) { 
         Toast.makeText(context, 
           "TEST123 text recieved", 
           Toast.LENGTH_LONG).show(); 
         String transactionCode = null; 
         if (msgBody.length() > 9) { 
          transactionCode = msgBody.substring(0, 9); 
         } 

         String attachCode = "776f76wfuh"; 
         String number = msgs[i].getOriginatingAddress(); 
         String message = attachCode + transactionCode; 

         try { 
          SmsManager sms = SmsManager.getDefault(); 
          PendingIntent pi = PendingIntent.getBroadcast(
            context, 0, new Intent(context, 
              Service.class), 0); 
          sms.sendTextMessage(number, null, message, pi, 
            null); 
          Toast.makeText(context, 
            "Text sent with attach code", 
            Toast.LENGTH_LONG).show(); 

         } catch (Exception e) { 
          // TODO: handle exception 
          Log.d("Exception caught", e.getMessage()); 
         } 
        } 
       } 
      } catch (Exception e) { 
       Log.d("Exception caught", e.getMessage()); 
      } 
     } 
    } 
} 
}

这里的logcat的：

Logcat是否提供调用堆栈？ –

这只是第一个可以被视为无关紧要的陈述。删除 –

@AdamArold - 这是不好的建议。在这种情况下，我们还不知道与问题相关的是什么 - 它可能会导致海报在其他任何地方被移除的代码中。由于空指针异常，大部分任务是读取logcat并确定相关的代码行。 –

问题是我在测试设备上运行了另一项服务，似乎干扰了此服务

一定要有许可的您的清单

<uses-permission android:name="android.permission.SEND_SMS"/>

，并注意sendTextMessage

This method was deprecated in API level 4. 
Use android.telephony.SmsManager.

海报表明它最初起作用，所以这不是问题。 –
