I have set up an alarm manager to go off at noon everyday and send a notification, and is working perfectly except for one part. When I open the app for the first time it immediately sends out a notification, regardless of the time.
Intent myIntent = new Intent(arg0, NotificationService.class);
myIntent.putExtra("compDate", tti.getEvents()[0][1]);
AlarmManager alarmManager = (AlarmManager)arg0.getSystemService(Context.ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(arg0, 0, myIntent, 0);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.HOUR, 12);
calendar.set(Calendar.AM_PM, Calendar.AM);
calendar.set(Calendar.DAY_OF_MONTH, 1);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
That method is being called by this piece of code in the onCreate method
int f = preferences.getInt("numberOfLaunches", 1);
if(f < 2){
alarmMethod();
f++;
editor.putInt("numberOfLaunches", f);
editor.apply();
}
That is the only time when it is being called
Most likely caused by this:
If the stated trigger time is in the past, the alarm will be triggered immediately

Make sure you set your first alarm to be in the future.
