当我在android中使用sendMultipartTextMessage发送消息时，NullPointer异常？

你好，我收到NullPointerException异常，当我发送消息，我不明白为什么这起了很大的作用。我下面贴我的代码： -当我在android中使用sendMultipartTextMessage发送消息时，NullPointer异常？

广播接收器： -

package z.z.z; 

import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.os.Bundle; 
import android.telephony.SmsMessage; 
import android.util.Log; 

public class SMSReceiver extends BroadcastReceiver 
{ 
    private SmsMessage[] msgs; 
    private String strNo,strMsgText; 

    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     try 
     { 
      Bundle bundle = intent.getExtras();   
      msgs = null; 
      String str = "";   

      if (bundle != null) 
      { 
       Object[] pdus = (Object[]) bundle.get("pdus"); 
       msgs = new SmsMessage[pdus.length]; 
       for (int i=0; i<msgs.length; i++) 
       { 
        msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]); 
        str += "SMS from " + msgs[i].getOriginatingAddress();      
        str += ":"; 
        str += msgs[i].getMessageBody().toString(); 
        str += "\n"; 
        strNo = msgs[i].getOriginatingAddress();  
        strMsgText = msgs[i].getDisplayMessageBody(); 

       } 

       context.startService(new Intent(context,IncomingSMSService.class)); 

      } 
     } 
     catch (Exception e) 
     { 
      e.printStackTrace(); 
     } 
    } 

}

IncomingSMSService： -

     super.onCreate(); 

     try 
     { 
      Log.d(TAG ,"****** in service try **----- "); 
      /* Read SMS from INBOX */ 
      Uri uriSMSURI = Uri.parse("content://sms/inbox");  
      Cursor cur = getContentResolver().query(uriSMSURI, null, "read = 0", null,null);  
      String sms = "";  
      while (cur.moveToNext()) 
      {   
        sms += "From :" + cur.getString(2) + " : " + cur.getString(11)+"\n"; 
    //    Log.d(TAG, "in SMS Service sms in loop :: "+ sms); 
      } 
      Log.d(TAG, "in SMS Service sms :: "+ sms); 


      Log.d(TAG ,"********** reverseNum ****** "+ Global.destNo); 
      ArrayList<String> ayyMsg = new ArrayList<String>(); 
      ayyMsg.add(sms); 
      SMSService.sendSMS(getBaseContext(), ayyMsg, Global.destNo); 
     } 
     catch (Exception e) 
     { 
      e.printStackTrace(); 
     } 
    }}

SendSMS

       catch (Exception e)

        e.printStackTrace();

      } 

**receiver**:- 

public static void receiver(Context context) 
    { 
     rmaReceiver = RMAReceiver.getSingleInstance(); 
     context.registerReceiver(rmaReceiver, new IntentFilter(SENT)); 

     //---when the SMS has been delivered---

这里是我的代码，当任何消息会出现，然后我的广播接收器将调用。从那开始，我开始从收件箱中获取未读邮件的服务以及我将作为消息发送的邮件。

我收到了收件箱中的邮件，但是当我将该邮件作为消息发送时，我得到了“空指针异常”。

请任何人都可以告诉我我错在哪里？

编辑：

我发现，当我在消息中发送文本的长度，然后它会给我空指针异常。正如我在谷歌搜索，我发现这是problrm解决使用sendMultipartTextMessage instaed使用sendTextMessage。但我已经使用过这种方法，为什么我会得到这个错误？

谢谢。

在您的问题中包含来自异常的堆栈跟踪。我不认为有人想在没有更多信息的情况下筛选代码来指导他们。 –

我编辑我的logcat错误。 – anddev

你好，我得到solution。我很高兴与大家分享。我用

ArrayList messages = sms.divideMessage（message）;

SmsManager sms = SmsManager.getDefault(); 
ArrayList<String> messages = sms.divideMessage(message); 
sms.sendMultipartTextMessage(destNumber, null, messages, ayySentPI, ayyDeliveredPI);
