There should be a "supported devices" in the api doc for the call. I suspect that this call isn't available on the f5+, kind of like how Weather is "since API Level 3.2.0", but not on the f5+, so a doc error is my guess...
Hi I found I had a problem on my system whereby I didn't have the SDK versions loaded that I thought I had. Once I fixed this I found 4.1.17 at least works as expected.
I did update the question (couldn't find how to delete it myself?) as soon as I realised, but you must have seen it beforehand. Sorry to have taken your time but thanks for responding.
You always want to use the current SDK, which is 4.2.4. While it may work with 4.1.7, it not being available on 4.2.4 could have been a bug fix. Do you have an actual f5+ to try it on?
I do have an F5+, I mentioned in my original question (which I realise you can't see now) I was getting the same problem on the simulator and the real device.
For now 4.1.7 is the latest version that I can get to run on my system --- higher versions give me a segmentation fault when I try to run the simulator via the `connectiq` command.
I have a relatively unusual environment, at least it seems in the Garmin/CIQ world (Void Linux/Vim/command line). It's been difficult but I've not asked questions about getting my general environment working, as I appreciate that my difficulties might be seen as self-inflicted and I don't want to get into philosophical debates about software choice.
I'm very happy to have a working environment now, and my app (including `getUserActivityHistory()`) is working in the simulator and on my real device.
I appreciate your advice about keeping my SDK up-to-date and will check regularly that I am at least using the latest version that I can get to work on my system.
