well i tried switching my activity call to private and a few other minor edits, but still the same error. since i'm still learning, in the spirit of what i'm "trying" to do with this activity call, could someone perhaps guide me as to if i am attempting it correctly or not? meaning if let's say i did want to call on the function of an activity from another activity (or service), is it correct to do:
private RegistersActivity mDisplay; mDisplay = new RegistersActivity(); mDisplay.populateGraph(); is that even correct in the spirit of what i am shooting for? in the mean time i'm going to attempt moving the data collection and graph into the service. but in my head i can't figure out why or how to get my original approach to work and feel like i'm missing something so obvious. i made the RegistersActivity call as i did as one would if you were calling on a function in a public class, and just thought to do the same. but i'm beginner so its likely very wrong. thanks for the help everyone:).
