Lost tracks

Not a Problem

Hiking on a rainy and cold day I twice managed to loose my recorded track:

I suppose that when I hit the "stop recording" button I accidentally (with my stiff fingers) hit again the "delete" button on the next screen, which appears at the same location. (I have no idea how I got across the next question "do you really want to delete". I just found that locus had been stopped when looking at the phone next time.)

Although it was definitvely my own fault, you might think of placing the "delete" button at a completely different location (maybe just exchange "delete" and "save" buttons - I hope nobody is so used to the location that he will accidentally delete his recordings after such a change).

Or is there a way to find a recorded (but not yet stored) track after deletion with an undelete tool? Where should I look, and which file name to look for?

Thank you !

Hi Hans-Peter,

you wrote that "I just found that locus had been stopped when looking at the phone next time". This problem is not about accidental pushing (and confirming) deleting your recorded track. Most probably your phone system battery optimization killed Locus process running in the background. Exclude Locus Map from this optimization - more info here: https://docs.locusmap.eu/doku.php?id=de:manual:faq:gps_lost_fix_android6 or here: https://dontkillmyapp.com/

Hallo Michal,

Thank you for the 2 links ! You could be right that one of the cases might be caused this way. Especially the info, that excluding Locus from the energy saving policy would not help to get the gps stopped by power management for my Samsung 7 was interesting news.

But I am still wondering why the track (which I had checked several times before) was completely lost.

Thanks again.

Hi Hans-Peter,

if Locus track recording is interrupted, the recorded track is automatically saved in Locus cache (more exactly Locus/cache/track_rec/). If there is an unfinished recorded track in this folder after Locus re-start, Locus detects it and offers it to save or go on recording. If not, then the data had been deleted either by the user or by the system automatic cache cleaning.

Hallo Michal,

Thank you for explaining the storage location and the recovery concept. I have seen this working several times - so in general I am quite happy with the robustness of Locus.

From the relevant dates I just see some files under Locus/cache/images and /images_int .

What kind of data is this ? Any chance to recover anything from herein ?

Hi Hans-Peter,

Locus/cache/images and /images_int contain just temporarily used images (geocache attachments etc.), not tracks data.

Thanks again. I give it up for this time...

But exchanging the buttons (as mentioned in the first comment above) might still be an idea to think of.
