Schedule a message using alarm manager

I'm working on an Android application which schedules messages to be sent. I'm making use of alarm manager. My main part of the code is as follows:

mConfirm.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        Intent intent = 
            new Intent(getApplicationContext(),MyNotificationService.class);

        mMessage = mEditTextMessage.getText().toString();
        mNumber = mEditTextNumber.getText().toString();
        c.set(mYear, mMonth, mDay);
        c.set(Calendar.HOUR_OF_DAY, mHour);
        c.set(Calendar.MINUTE, mMinutes);

        Bundle bundle = new Bundle();
        bundle.putCharSequence("number", mNumber);
        bundle.putCharSequence("message", mMessage);
        intent.putExtras(bundle);

        AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
        PendingIntent pendingIntent = 
            PendingIntent.getService(getApplicationContext(), 0, intent, 0);
        alarmManager.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), 
            pendingIntent);
    }
});

How should I implement MyNotificationService class so that it sends the message at the set time? Should that class be a Service or a Broadcast receiver?

You can use the Broadcast receiver for receiving messages from the intent. You can create a receiver class where you can have your messages. 

Intent intent=new Intent(MyReceiver.ACTION_REFRESH_ALARM);
pendingIntent=PendingIntent.getBroadcast(this, 0, intent, 0);
alarmManager=(AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,0,pendingIntent);

public class MyReceiver extends BroadcastReceiver
{

   public static final String ACTION_REFRESH_ALARM ="com.paad.network.ACTION_REFRESH_ALARM";

@Override
public void onReceive(Context context, Intent intent) {

             //Extract Messages
}}

Below code will allow you to call a broadcast receiver after every 5 seconds.You can use set() ot setTimeZone() method to set at a particular time.

AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class);
intent.putExtra("abc", Boolean.FALSE);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
//After after 5 seconds
am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 5 , pi);

AlarmManagerBroadcastReceiver class is a broadcaster.
