Don't forget permissions:

    ....
    <uses-permission android:name="android.permission.WAKE_LOCK"/>
    <uses-permission android:name="android.permission.VIBRATE"/>
    ....
    AND broadcast receiver in application tag:        
    <receiver android:process=":remote" android:name="Alarm" />
  ....

Thanks

You can use a pendingIntent with a BroadCastReceiver like this:

Calendar cal = Calendar.getInstance();
Intent activate = new Intent(context, Alarm.class);
AlarmManager alarms ;
PendingIntent alarmIntent = PendingIntent.getBroadcast(context, 0, activate, 0);
alarms = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
cal.set(Calendar.HOUR_OF_DAY, hour);
cal.set(Calendar.MINUTE, minute);
cal.set(Calendar.SECOND, 00);
alarms.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), alarmIntent);

Then the BroadCast Receiver:

public class Alarm extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
      MediaPlayer mp = MediaPlayer.create(context, R.raw.ferry_sound);
      mp.start();
      PowerManager pm = (PowerManager)     context.getSystemService(Context.POWER_SERVICE);
      PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Tag");
      wl.acquire();
      Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
      long[] s = { 0, 100, 10, 500, 10, 100, 0, 500, 10, 100, 10, 500 };
      vibrator.vibrate(s, -1);
   }
}

Don't forget to include these permissions in your AndroidManifest.xml:

....
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.VIBRATE"/>
....

and broadcast receiver in application tag:

<receiver  android:process=":remote" android:name="Alarm" />
