Unable to record tracks

[nickw7coc]

For some time I've been unable to record tracks with the app Ver 3.8.4 on my Huawei Mate P20 Pro, Android 10.1.0.329.

I've got the default profile as Walking.

The record button is showing on the screen and when I touch it, it indicates that it's recording, though there's no recorded track shown, though when I press the button again it prompts me 4 options, and if I Save it I'm not offered any options, and therefore am not able to go off and find the file...? When the app is not displaying, or the screen is locked, the notification bar at the top of the screen doesn't show that I'm recording a track, and dragging down from the top shows that there's a track being recorded, but it never progresses past zero time or distance...

Any help gratefully received :)

Sorry to assume your ignorance, but, have you looked in the My Places -> Tracks screen? That's where it's saved, even if you don't click that 'Save' button (that did throw me off for a while after that update), in either the 'rec' or monthly subfolders according to the plugin setting. That's also where, if things are working correctly, you can set the 'Currently recording track' to be visible.

If you already know all about these things, then it's a trickier thing, I suppose, and beyond me.

As you can see, there's nothing recorded, even though I have tried many times, including my dog walk yesterday...

I get the same. did you find out what was going on here?

Same for me: OsmAnd 4.4.7, Android Go 11.

The track recording is on, my position is displayed on the map (a downloaded standard map vector), I'm walking, my position is right, but no track is recorded or visible. Same screen as @nickw7coc.

Android Go edition is a stripped-down version of the OS with among others several system services removed. I guess we would have to investigate if anything used for track recording is not present in Android Go. The capability to run a foreground service comes to mind (does navigation work? It also acts as a foreground service.) Does GPS work, i.e. do you see satellite reception, e.g. via OsmAnd's GPS widget?

PS1: Allegedly Google Play Serrvices is heavily modified in Android Go, so it may be worth trying OsmAnd Setting "Android API" as location source.

PS2: Does anybody still experience this with a newer OsmAnd version under regular Android OS?

[luigifab]

Yes GPS is working. My position is displayed on the map, and updated when I move.

First the setting:

Then I stopped the application and restarted my phone. I checked that the setting is unchanged.

I'm ready:

I started the recording:

I walked ~100m, nothing is displayed, and after finish the recording, nothing is saved:

No difference if you leave the screen on with the app in the foreground, so we can exclude a power management issue, right? And I assume your recording interval is not exceptionally long, so within 100m of walking there should be a few measurement points?

Can you try to use the 'Plan a trip' functionality to create a short track and save it, to make sure OsmAnd has no problrem writing files to the tracks folder? (You should see that track then in MyPlaces=Tracks.)

[luigifab]

I tried again, screen always on, app always in the foreground, GPS reception ok (~20/49). 2 km with "Android API", 2 km wih Google Play Services.

I started the "Trip recoding" twice, and finished it twice. During the "Trip recording", I checked my position several times, and always good. The "Map orientation" is: "Movement direction", worked all the time.

"My Places > Tracks" still empty. Not sure how to test if OsmAnd can write or not in the folder, but I tried to "Plan a route", and the GPX is saved in Android/obb/net.osmand/tracks. The GPX is present in "My Places > Tracks".

[luigifab]

And yes, configuration of trip recording is:

• general logging interval: 2s
• minimum displacement: 2m
• minimum accuracy: 1m
• minimum speed: 2 km/h

I see a button reset plugin settings, I'm trying.

[pebogufi]

Try to increase minimum accuracy to a higher value of about 50 m for test. Does it change recording ? Do you get track values ?

[luigifab]

Yes, true. I selected "Not selected" for "Minimum accuracy", and now the "Trip recording" works. That's lol because when I set up OsmAnd a few weeks ago, I looked to display the accuracy in the top right of the map, but I couldn't find the setting.

I just tested with 50m, also working.

[pebogufi]

I made also a test with minimum accuracy =5 m. (My normal setting is 50 m) For 600 m NO points recorded, OSM tracker recorded 57 points. @sonora I think there should be a warning if minimum accuracy is set to less then 15 or 10 m, that this might result in very few points or no points at all recorded.

[sonora]

Yes in fact, filtering tracks during recording is rather critical as it (and particularly its extent) usually goes unnoticed.

I had once proposed to indicate the number of filtered points during recording, so that in this case the notification would have displayed the number of points as something like "0 (47 filtered out)" or similar.

It has never been implemented, but I think it still is a good idea (perhaps @vshcherb).
