android sms sender name returns null

问题

Greetings.

I am trying to read the sms sender name using the following code. The variable name is always null. Please let me know what is the problem with code. It returns address properly But the name is null

        ContentResolver contentResolver = getContentResolver();        
        Cursor mCursor = contentResolver.query( Uri.parse( "content://sms/inbox" ), null, null, null, null);                 

        if(mCursor.getCount()==0)
              return;

        startManagingCursor(mCursor);   

        mCursor.moveToFirst();

                String fromadd = mCursor.getString(mCursor.getColumnIndex("address"));
                           String name = mCursor.getString(mCursor.getColumnIndex("person"));
