Set alarms for a specific date in the future (alarm, not a reminder!)
Have you found yourself in a situation where you wanted a strong reminder to something someday in the future?!
A reminder wouldn't really do since it would just give you a notification, an e-mail, or a small pling which can get lost in the abyss of notifications we receive every day.
Have you thought, "Wish I could set an alarm for a future day/time"?
Don't worry, RemindMe! Got you covered.
PS: SYSTEM_ALERT_WINDOW permission is used because Android wouldn't let me start an activity from the background. Hence, I display a transparent system overlay for a very small duration (500 ms), then open the alarm activity as soon as the overlay gets drawn, and close the overlay later.
