Android PendingIntent extras, not received by Broa

Question

When I pass extras to a PendingIntent, the message is never received by the sendBroadcastReceiver, because the onReceive() method of this BroadcastReceiver is never called. Why is this happening?

public class MainActivity extends Activity {
    private static String SENT = "SMS_SENT";
    private static String DELIVERED = "SMS_DELIVERED";
    private static int MAX_SMS_MESSAGE_LENGTH = 160;

    private static Context mContext;
    private BroadcastReceiver sendBroadcastReceiver, deliveryBroadcastReceiver;
    private final String DEBUG_TAG = getClass().getSimpleName().toString();

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

        // ---when the SMS has been sent---
        sendBroadcastReceiver = new BroadcastReceiver() {

            public void onReceive(Context arg0, Intent arg1) {
                switch (getResultCode()) {
                    case Activity.RESULT_OK:
                        Toast.makeText(getBaseContext(), "SMS Sent", Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                        Toast.makeText(getBaseContext(), "Generic failure", Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_NO_SERVICE:
                        Toast.makeText(getBaseContext(), "No service", Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_NULL_PDU:
                        Toast.makeText(getBaseContext(), "Null PDU", Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_RADIO_OFF:
                        Toast.makeText(getBaseContext(), "Radio off", Toast.LENGTH_SHORT).show();
                        break;
                    }
            }
        };
        // ---when the SMS has been delivered---
        deliveryBroadcastReceiver = new BroadcastReceiver() {
            public void onReceive(Context arg0, Intent arg1) {
                switch (getResultCode()) {
                    case Activity.RESULT_OK:
                        Toast.makeText(getBaseContext(), "SMS Delivered", Toast.LENGTH_SHORT).show();
                        break;
                    case Activity.RESULT_CANCELED:
                        Toast.makeText(getBaseContext(), "SMS not delivered",Toast.LENGTH_SHORT).show();
                        break;
                }
            }
        };

        Log.d(DEBUG_TAG, "onCreate() : Register receivers");
        registerReceiver(deliveryBroadcastReceiver, new IntentFilter(DELIVERED));
        registerReceiver(sendBroadcastReceiver, new IntentFilter(SENT));

        mContext = getApplicationContext();

        setContentView(R.layout.main);
        // ... Bind views and set up onClick listeners ( for example, one to call sendSMS() )

    }

    @Override
    protected void onDestroy() {
        // Unregister receivers
        Log.d(DEBUG_TAG, "onDestroy() : Unregister receivers");
        if (sendBroadcastReceiver != null) {
            unregisterReceiver(sendBroadcastReceiver);
            sendBroadcastReceiver = null;
        }
        if (deliveryBroadcastReceiver != null) {
            unregisterReceiver(deliveryBroadcastReceiver);
            deliveryBroadcastReceiver = null;
        }
        super.onDestroy();
    }

    // ---sends an SMS message to another device---
    public static void sendSMS(String phoneNumber, String message) {
        Intent sendIntent = new Intent(SENT);
        sendIntent.putExtra("extra_key", "extra_value"));

        PendingIntent piSent = PendingIntent.getBroadcast(mContext, 0, sendIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        PendingIntent piDelivered = PendingIntent.getBroadcast(mContext, 0, new Intent(DELIVERED), 0);
        SmsManager smsManager = SmsManager.getDefault();

        int length = message.length();
        if (length > MAX_SMS_MESSAGE_LENGTH) {
            ArrayList < String > messagelist = smsManager.divideMessage(message);
            smsManager.sendMultipartTextMessage(phoneNumber, null, messagelist, null, null);
        } else 
            smsManager.sendTextMessage(phoneNumber, null, message, piSent, piDelivered);
        }
   }

I guess there are some issues with registering and unregistering in the code. Instead I registered the two BroadcastReceivers in the AndroidManifest.xml file and was able to successfully pass extras.
