SMS Receiver rubbishness :p

Hi Guys...

Code (Text):

1. package net.learn2develop.SMSMessaging;
2.  
3. import android.content.BroadcastReceiver;
4. import android.content.Context;
5. import android.content.Intent;
6. import android.os.Bundle;
7. import android.telephony.SmsMessage;
8. import android.widget.Toast;
9.  
10. public class SMSReceiver extends BroadcastReceiver
11. {
12.     @Override
13.     public void onReceive(Context context, Intent intent)
14.     {
15.         //---get the SMS message passed in---
16.         Bundle bundle = intent.getExtras();        
17.         SmsMessage[] msgs = null;
18.         String str = "";            
19.         if (bundle != null)
20.         {
21.             //---retrieve the SMS message received---
22.             Object[] pdus = (Object[]) bundle.get("pdus");
23.             msgs = new SmsMessage[pdus.length];            
24.             for (int i=0; i<msgs.length; i++){
25.                 msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);                
26.                 str += "SMS from " + msgs[i].getOriginatingAddress();                    
27.                 str += " :";
28.                 str += msgs[i].getMessageBody().toString();
29.                 str += "\n";        
30.             }
31.             //---display the new SMS message---
32.             Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
33.         }                        
34.     }
35. }
