Question

i have the following code which gives a receiver not registered through an illegal argument exception

public class CheckServer extends IntentService
{

public String snumber;

public CheckServer()
{
  super("CheckServer");
}


@Override
public void onCreate()
{
  super.onCreate();

  String DELIVERED = "SMS_DELIVERED";

  DeliveryReceiver dReceiver = new DeliveryReceiver();

  registerReceiver(dReceiver,new IntentFilter(DELIVERED));

}

@Override
public void onDestroy()
{
  super.onDestroy();

  DeliveryReceiver dReceiver = new DeliveryReceiver();

  unregisterReceiver(dReceiver);
  dReceiver = null;
}


@Override
protected void onHandleIntent(Intent intent)
{
  try
  {
    serviceAction();
  }
  catch (ClientProtocolException e)

      response = client.execute(request);


  }
}

the problem is that i get a register not received error even though i register it in the onCreate() method, what might be the problem?

Answer 1

Instead of registering in onCreate() and unregistering in onDestroy() methods, I changed the sendSMS method to following:

public void sendSMS(String number,String message,String serialnum) 
{  
  String DELIVERED = "SMS_DELIVERED";

  Intent delivered = new Intent(DELIVERED);
  delivered.putExtra("MsgNum", serialnum);
  PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, delivered, 0);

    registerReceiver(
        new BroadcastReceiver() 
        {   
            @Override
           public void onReceive(Context context, Intent intent)
           {
                       switch (getResultCode())
                       {
                           case Activity.RESULT_OK:

                               Toast.makeText(getBaseContext(), "SMS delivered",Toast.LENGTH_SHORT).show();

                               updateSMSStatus USS =  new updateSMSStatus();

                               USS.execute(intent.getStringExtra("Msgnum"));

                               break;

                           case Activity.RESULT_CANCELED:

                               Toast.makeText(getBaseContext(), "SMS not delivered",Toast.LENGTH_SHORT).show();

                               break;                        
                       }

                     unregisterReceiver(this);
            }

        },
        new IntentFilter(DELIVERED)); 

    SmsManager smsMngr = SmsManager.getDefault();
    smsMngr.sendTextMessage(number, null, message, null, deliveredPI);

}

The sms delivered action is now triggered, thanks all.

Any ideas on how to differentiate the delivery reports of each sms?

I’m not pretty sure on how to use the intent.putExtra() method in my service with the delivery BroadcastReceiver.
