I am trying to set up a reminder feature. The user will input a time, hit a button, and a notification will be sent out at that time. However I cannot get the notification to fire at theexact time despite how I've switched up my code. Below is the code for my service, receiver, activity, and manifest. I have even tried .setWindow() but no matter what I try I'll usually get the notification within 5-10 minutes....If there is gonna be a delay it can be no larger than one minute if possible. Any help would be gratefully appreciated.

EDIT-Try to refrain from linking to other questions please. I have google searched this topic to heck and back and until I get the answer I will continue to google so chances are I have at least seen every Stack Overflow on the subject.
