Android Emulator not working for Alarm Reminder program

I am new to Android. I have tried an sample application for status bar reminder for mentioning date. But it is not working in Emulator, i don't know what i am missing. I have attached the sample code here

Main.java

Calendar cal = Calendar.getInstance();       
    cal.set(Calendar.MONTH, 3);
    cal.set(Calendar.YEAR, 2012);               
    cal.set(Calendar.DAY_OF_MONTH, 25);
    cal.set(Calendar.HOUR_OF_DAY, 22);
    cal.set(Calendar.MINUTE, 8);
    cal.set(Calendar.SECOND,0);
    Intent alarmintent = new Intent(getApplicationContext(), AlarmReceiver.class);
    PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(), 1,alarmintent,PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);
    am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);

In the alarm receiving class i have the following code

AlarmReceiver.java

 public class AlarmReceiver extends BroadcastReceiver {
 NotificationManager nm;
 public void onReceive(Context context, Intent intent) {
 nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
 CharSequence from = "Raja";
 CharSequence message = "My First App...";
 PendingIntent contentIntent = PendingIntent.getActivity(context, 0,new Intent(), 0);
 Notification notif = new Notification(R.drawable.ic_launcher,"Crazy About Android...", System.currentTimeMillis());
 notif.setLatestEventInfo(context, from, message, contentIntent);
  nm.notify(1, notif);
  }
 }

In the manifest file i have added the following line (before the application tag close) for Alarm receiving class

  <receiver android:name=".AlarmReceiver"></receiver>

Log cat entries

PendingIntent contentIntent = PendingIntent.getActivity(context, 0,new Intent(), 0);

You are passing a blank Intent here . Change this to the intent of Activity you want to all, for example :

PendingIntent contentIntent = PendingIntent.getActivity(context, 0,new Intent(context,MyActivity.class), 0);

Try the following Activity:

public class TestAlarmActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
     // get a Calendar object with current time
        Calendar cal = Calendar.getInstance();
        // add 5 minutes to the calendar object
        cal.add(Calendar.MINUTE, 5);
        Intent intent = new Intent(this, AlarmReceiver.class);
        intent.putExtra("alarm_message", "O'Doyle Rules!");
        // In reality, you would want to have a static variable for the request code instead of 192837
        PendingIntent sender = PendingIntent.getBroadcast(this, 192837, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        // Get the AlarmManager service
        AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
        am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+5000, sender);
        Toast.makeText(this, "tii;;; inside", Toast.LENGTH_LONG).show();
    }

and the following Broadcastreceiver:

public class AlarmReceiver extends BroadcastReceiver {

    private NotificationManager nm;

    @Override
    public void onReceive(Context context, Intent arg1) {
        // TODO Auto-generated method stub
        Toast.makeText(context, "inside", Toast.LENGTH_LONG).show();
        nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
         CharSequence from = "Raja";
         CharSequence message = "My First App...";
         PendingIntent contentIntent = PendingIntent.getActivity(context, 0,new Intent(), 0);
         Notification notif = new Notification(R.drawable.ic_launcher,"Crazy About Android...", System.currentTimeMillis());
         notif.setLatestEventInfo(context, from, message, contentIntent);
          nm.notify(1, notif);
    }

I think your alarm is not getting executed because it has already passed as you are passing day of month as 25
