AlarmClock for Beginners - Android

This is working code in version 10. You need to set up an intent to start a new instance of the AlarmClock. make sure to assign the constants EXTRA_HOUR and EXTRA_MINUTE to your own variables names or hard coded constants. In this example they are coded to user entered time taken from the Calendar (located in the java.util.Calendar).

Intent openNewAlarm = new Intent(AlarmClock.ACTION_SET_ALARM);        openNewAlarm.putExtra(AlarmClock.EXTRA_HOUR, hour_alarm);        openNewAlarm.putExtra(AlarmClock.EXTRA_MINUTES, minute_alarm);        startActivity(openNewAlarm);

this next section obtains the current time from the internal clock and returns it in a TimePicker Here the user can next enter a new time and return it to the Intent to set a new alarm.

public Dialog onCreateDialog(Bundle savedInstanceState) {        // Use the current time as the default values for the picker        final Calendar c = Calendar.getInstance();        hour_local = c.get(Calendar.HOUR_OF_DAY);        minute_local = c.get(Calendar.MINUTE);        // Create a new instance of TimePickerDialog and return it        return new TimePickerDialog(getActivity(), this, hour_local, minute_local,                DateFormat.is24HourFormat(getActivity()));    } 

To use a TimePicker create an inner static class, one that is inside of the Activity the calls it. Look at this http://developer.android.com/reference/android/widget/TimePicker.html
