從CDMA發送短信（htc evo）拋出空指針異常

Question

我正在做一個應用程序，我必須從CDMA手機發送短信，但它會引發空指針異常。我使用

smsmanager.sendDataMessage(phonenumber, null, (short)1001, msgStr.getBytes(), sentPI, deliveredPI); 

它拋出如下錯誤： -

下面是函數

 String SENT = "SMS_SENT"; 
    String DELIVERED = "SMS_DELIVERED"; 

    PendingIntent senDPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(SENT), 
      0); 

    PendingIntent deliveredPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(
      DELIVERED), 0); 

    SmsManager sms = SmsManager.getDefault(); 

    short s = Short.parseShort(portStr); 
    short port = s; 

    Log.d("Data", "Sending SMS TO :: "+phonenumber); 
    Log.d("Data", "Sending SMS MESSAGE :: "+msgStr); 
    Log.d("Data", "Sending SMS on PORT :: "+port); 

    sms.sendDataMessage(phonenumber, null, port, msgStr.getBytes(), senDPI, deliveredPI); 

所有PHONENUMBER，msgStr，港口來源於我的XML佈局文件的EDITTEXT領域。 我在這裏錯過了什麼？ 幫助讚賞。
