In Android we set an alarm by setting the time until it goes off in milliseconds. Is there an easy way to find how many milliseconds there are until a certain time (hh:mm) or do I just have to calculate it mathematically?
Thanks!

Check out the first argument for AlarmManager.set(): With RTC/RTC_WAKEUP, you can specify a fixed time rather than an elapsed time.
That said, if you need to use the elapsed time, it’s pretty trivial to calculate the number of milliseconds that need to elapse. Worst case, you could use the
Calendarand/orDateclasses.
