web service int java.lang.String.lengt() hatası

Selamlar gelen kutusundaki smsleri sql veritabanına aktarmaya çalışıyorum  log ekranımda  " Attempt to invoke virtual method    ' int java.lang.String.length() ' on a null object reference "  hatası veriyor .  Web servisimde kendim veri girince çalışıyor ancak telefondan bilgi gönderemiyorum sebebi ne olabilir ?

   Uri uriSMSURI = Uri.parse("content://sms/inbox");
		
		
		Cursor cur = getContentResolver().query(uriSMSURI, null, null, null,null);
		String sms = "";
		long tim;
		
		
		if(cur.moveToFirst()){
			do{
				
	
				String date = cur.getString(cur.getColumnIndex("date"));
				Long timestamp = Long.parseLong(date);

				SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy/HH:mm");
				Calendar calendar = Calendar.getInstance();
				calendar.setTimeInMillis(timestamp);
				String finaldate = dateFormat.format(calendar.getTime());
			 String	 smsDate = finaldate.toString();

				//InboxSmsDate=smsDate;
				//				name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));

				InboxSmsFrom=cur.getString(2);
				InboxSmsBody=cur.getString(12);
				InboxSmsDate=smsDate;
				
				
				new ToastMessageTask().execute(InboxSmsDate, InboxSmsBody,InboxSmsFrom);
				
				
				
			}while(cur.moveToNext());
			
			
		}
