Android Alarmmanager: How To Find Out The Time Remaining To Trigger The Pendingintent

I am developing an alarm clock app. Below I have a function to set the alarm. But I want to know how to find the remaining time AlarmManager to trigger the PendingIntent. For examp

Solution 1:

You can calculate the difference between your alarm time (totalTime) and the current time like this:

long timeDiffInMillis = totalTime - System.currentTimeMillis();

This will give you the time remaining before your alarm will trigger (in milliseconds).
