collecting data in background

I'd like to write app/widget that collecting some data all the time even if it doesn't run in foreground.

I know that I can do one shot from app to background but how it repeat if app is not in foreground?

Can I call registerForTemporalEvent from onTemporalEvent to repeat reading data in 5 minutes?

Can background use Storage.setValue to save data for app?

In the background service use Background.getBackgroundData(), and append the new data to that before calling Background.exit()

ok, but question is how to repeat onTemporalEvent if only background run

-----app/widget

- start

- in app.func I call registerForTemporalEvent

- exit app

----background

onTemporalEvent

- append new data (but easier would be Storage.setValue())

- and call next registerForTemporalEvent (beiing in onTemporalEvent) - is it possible?

there is no info in doc but probably I can't use Storage.setValue in background...

hi, see answer here:

https://developer.garmin.com/connect-iq/core-topics/persisting-data/

API level 3.2.0 introduced the ability to access the Storage module from background processes. The background process can modify storage using Storage.setValue(), Storage.deleteValue() and Storage.clearValue(). When the storage is written from the background process, AppBase.onStorageChanged() callback will be invoked for the foreground process if the background and foreground process are active at the same time and vice-versa. The application would then have to reload data from storage to reflect updated information.

thx, so I'll have to think something else need from 2.4...

Can I call registerForTemporalEvent from (beinng in) onTemporalEvent?

You can just use a registerForTemporalEvent call in your AppBase with a duration (say every 5 minutes), and that way the backgrougd service runs every X minutes without re-registering

yes, I've forgotten about this
