Is there a way to keep functions from one page running after switching to another page? For a very simple example, if I’m running a timer on page 1, is there a way to keep that timer running after I switch to page 2? I have been storing the processed data from page 1 into local storage, then inject…

This is a difficult question to answer in the abstract, but in general everything that is not directly involved with user interaction - including what sounds like making “processed data” and timers - belongs IMHO in a service provider, not a page. Hopefully that’s all the information you need, beca…

Right, I for some reason forgot what service provider was called. That’s what I have been doing with Ionic storage. I’m doing some device motion tracking and logging the data. I have been importing the service to every page and restarting the service. It feels tedious and I wasn’t sure if that’s how…

[image] ybh1231ip: restarting the service Maybe this is just semantics, but I’ve never had to “restart” a service, so I’m not sure what you mean here.

[image] ybh1231ip: I for some reason forgot what service provider was called. :thinking: no idea what you are trying to say here but as pointed out you’re better off with singleton services injected at root and use observables to pass around your data and if you really need local storage cons…

What I’m doing now: Made a service, it make uses of device motion to track some movements and do some calculations based on the movements. Import the service to every page. ngOnInit, I retrieve the processed data from storage, and resume my service. ngOnDestroy, I stop the service and store everyt…

I guess if you’re happy with it, that’s all that matters. Everything about that sounds completely crazy to me, but that’s probably simply because I don’t really understand what you’re trying to do.

I’m trying to use device motion to log the movements of the phone and do some calculations using the motion data in combination with some other things that I get from a web server. I want the program to continuously track the motion and do the calculations in every page in the app until the user ask…

As either name implies, service providers are supposed to “serve” and “provide”, so I don’t think of the concepts of “stop” and “resume” as applying to them at all. I can’t do anything with “do some calculations” and “some other things I get from a web server”. Everything is so vague. Maybe you wou…
