無法啓動接收器NullPointerException

我有一個BroadcastReceiver接收短信，然後應該立即發送回覆短信，如果文本有某些字符。現在它收到併發送短信，但它很快強制關閉給出類似如下：無法啓動接收器... NullPointerException ... LogCat中的ActivityThread.handleReciever（釋義）...可能是什麼問題？這裏是我的代碼，你要尋找的ELSE IF語句（這是我目前測試的部分）：無法啓動接收器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()); 
      } 
     } 
    } 
} 
}

這裏的logcat的：

Logcat是否提供調用堆棧？ –

這只是第一個可以被視爲無關緊要的陳述。刪除 –

@AdamArold - 這是不好的建議。在這種情況下，我們還不知道與問題相關的是什麼 - 它可能會導致海報在其他任何地方被移除的代碼中。由於空指針異常，大部分任務是讀取logcat並確定相關的代碼行。 –

問題是我在測試設備上運行了另一項服務，似乎干擾了此服務

一定要有許可的您的清單

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

，並注意sendTextMessage

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

海報表明它最初起作用，所以這不是問題。 –
