Android recently looked at the alarm clock and Management (AlarmManager), I really do not mistake, powerful and simple, the code is as follows:

1, a AlarmReceiver inherited into BroadcastReceiver, and AndroidManifest.xml statement
public static class AlarmReceiver extends BroadcastReceiver (
@ Override
public void onReceive (Context context, Intent intent) (
Toast.makeText (context, "Alarm prompts: Time to!", Toast.LENGTH_LONG). Show ();

2, the establishment of Intent and PendingIntent, to call the target component.
Intent intent = new Intent (this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast (this, 0, intent, 0);

3, set the alarm clock management for instance:
AlarmManager alarmManager = (AlarmManager) getSystemService (Context.ALARM_SERVICE);
Set single-alarm clock:
alarmManager.set (AlarmManager.RTC_WAKEUP, System.currentTimeMillis () + (5 * 1000), pendingIntent);
Set the alarm clock cycles:
alarmManager.setRepeating (AlarmManager.RTC_WAKEUP, System.currentTimeMillis () + (10 * 1000), (24 * 60 * 60 * 1000), pendingIntent);

Done! Of course, dealing here only with the response alarm text, you can play sounds, or have a system with more complex notification, where you are God, and everything you do
