Java FIT SDK: How can I get the time in motion (total_moving_time / "Zeit in Bewegung")?

With the Java FIT SDK I am able to get e.g. total_timer_time and total_elapsed_time, but the field total_moving_time (see e.g. `com.garmin.fit.SessionMesg`) seems to be never set / available.

Neither the example or default decoder and listener implementations nor via custom ones I am able to get a value for the total_moving_time.
But the Garmin Connect app shows values for "Zeit in Bewegung" (time in motion?) and similar values (e.g. moving_speed) for the same activities.

I tried several different activity / sport types, e.g. running, walking, cycling. And I tried / listed all SessionMesg fiels, all LapMesgFields, and essentially all FitMessages.

Can somebody point me in the right direction for getting values for time in motion (total_moving_time)?

Moving time is not stored in FIT Activity files created by Garmin devices. Other apps or devices may set it though. When it is not set, most platforms will calculate it based on a speed threshold. Everyone does it a little different, but some threshold slightly above zero is normal.

But here is a passage about "Elapsed, Timer, and Moving Duration" in FIT Files, is this something else then total_moving_time?

That article provides a definition of moving time and how it compares to the other time values, it does not say that moving time is required to be written to a FIT Activity file. The session and lap messages both have a total moving time field, but I am not aware of any device, Garmin or otherwise, that use that field. Which is why most platforms will calculate moving time from the record messages based on a speed threshold.

Ah got it, thank you!

Has anyone already a got Implementation of smth like that to share? I was thinking GPS/Speed alone might be misleading, maybe a combination of speed, power/cadence (if available)?

Thnx in advance, Tim
