Question

Ok, guys, I have this repeated tasks to do, so I schedule cupple Alarms:

private static void scheduleAlarm(Context context, AlarmManager alarmManager, String action, long interval) {
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, new Intent(action), PendingIntent.FLAG_UPDATE_CURRENT);
        alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + interval, pendingIntent);
}

But, when I change system time, all my Alarms are broken, i.e. they eventually fire, but when the system time becomes the same as time for alarms.

How do I deal with this issue?

Answer 1

When the user changes the system time, an event is broadcast with this Intent action: android.intent.action.TIME_SET

You can listen for this Intent and reschedule your alarms.
