问题
I have trouble implementing Reminder for my app.i did research but couldnt find proper solution. what i want is:
i am developing an android app which has one feature to remind users about the selected event 30 min before event start.
i will be displaying the date and time of the event in textview,on click of reminder button reminder will set 30min before event. how can i proceed to implement this.
- Note: i dont want to use date/time picker, specific date and time will be taken directly from text view which i will display.
Any suggestion/links with logic please help.
if any one can help dn please tell me the logic to add future,date + hours + minutes to current time to set alarm(date and time will be taken from textview)
