Edge Datafield running more than one instance

Hi there!

I‘m developing datafields for Edge devices. On an Edge device you have usually 3 or 4 activity profiles: Road, Mountainbike, Indoor and so on.

In general, it is not a problem to use one and the same data field in several profiles.
But it becomes a problem if the profile is changed during a running recording without save or exit the first activity - and so the data field is loaded in second instance. (Yes, users really do that!)
This leads to problems with data playback.

Now my question:
Is there a way for data fields to check if it is simultaneously loaded another time? So, to determine if one instance is already running while another one is to be loaded?

Thanks!

Per my observations, when you change the activity profile on the Edge device, the first instance shuts down (AppBase.onStop() method is being called), and the second instance starts up (AppBase.onStart() method is being called). So if you need to transfer your data from one instance to another then you probably have to save and backup it from storage inside these 2 methods.

Ok, thank you. That sounds logical.
