You have a bug in your code, where you are supplying the wrong time. >> 2.

As the last comment on the accepted answer indicates, that code does not indicate whether hour and min are zero. > Anyone know what is wrong with the OP's code? Presumably, hour and min are zero.

Which means that you are setting the alarm time to the current time. Here is some sample code showing setting a recurring alarm to occur every day at the same time, culled from a SharedPreference: public static void setAlarm(Context ctxt) { AlarmManager mgr=(AlarmManager)ctxt.getSystemService(Context.ALARM_SERVICE); Calendar cal=Calendar.getInstance(); SharedPreferences prefs=PreferenceManager.getDefaultSharedPreferences(ctxt); String time=prefs.getString("alarm_time", "12:00"); cal.set(Calendar.HOUR_OF_DAY, TimePreference.getHour(time)); cal.set(Calendar.MINUTE, TimePreference.getMinute(time)); cal.set(Calendar.SECOND, 0); cal.set(Calendar.MILLISECOND, 0); if (cal.getTimeInMillis()<System.currentTimeMillis()) { cal.add(Calendar.DAY_OF_YEAR, 1); } mgr.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, getPendingIntent(ctxt)); } -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Warescription: Three Android Books, Plus Updates, One Low Price! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
