Is this retrieval of an SMS message body redundant?

Question

I got this code from somewhere, a book I think: public class KITSMSReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { // get the SMS message that was received Bundle bundle = intent.getExtras(); SmsMessage[] msgs = null; String str = ""; Log.d(LOGTAG, "DavyCrockettKingOfTheWildFrontier.onReceive"); if (bundle != null) { Object[] pdus = (Object[]) bundle.get("pdus"); msgs = new SmsMessage[pdus.length]; String senderTel = ""; for (int i = 0; i < msgs.length; i++) { // get the body of the message msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]); // get the msg body str += msgs[i].getMessageBody().toString(); str += "\n"; } . . . ...but now as I look at the comments I'm a bit bamboozled. One line says: "get the body of the message" and then the next line says, "get the msg body". If this is really "the preferred method" for extracting the SMS body, why does it appear, according to the comments, to be done twice?

Answer 1

This is because pdus is binary data which is converted into array of SMSMessage object using msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]); while from this object to fetch actual message string below line is used msgs[i].getMessageBody().toString();
