Is there a way to export the location data to use with other applications?

Currently you have to go through the server app to then export the data. I understand they're meant to work together, but for someone who just cares about the data and the features of the android app, it would be more convenient to just get the data without going through the hassle of hosting the web app.

Add a license file

It will be nice to have this feature.

P.S.: Thank you for developing this software!

I would like to synchronize a saved track a second time, e.g. after removing and reinstalling ulogger-server. I could not find a way within the Android app to tell ulogger to synchronize a track a second time. It tells me the track has already been synchronized, which is not quite true since I blew away and reinstalled the server.

Hi, first thanks for making a network-location-only tracker. The GPS isn't reliably switched off.

Steps to reproduce:
Stop all other GPS apps. Configure network+GPS location. Start recording a new offline track. Configure network location only, but do not restart recording. Wait a bit. Check the recorded data with Oandbackup and Amaze.

Observed:
GPS datapoints keep getting recorded. The battery keeps getting drained.

Expected behavior:
GPS should not be active at all after configuring network location only.

Hello,

I´m running µlogger on my Oneplus3 with Android 8. Since this update logging is not reliable working with µlogger.
If it is in front and the screen is on everything works fine, but if it goes in background logging stops.

Turning navigation on in google maps solves the problem at the moment. Logging works again.

Best regards, Stefan

Useful when ulogger website is stored on lan and is currently unavailable. It is already possible to export the gpx file but not to import it later on. It might be useful.

Steps to reproduce:
Install app. Configure network+GPS location sources. Start recording a new (offline) track.

Observed behavior:
The app never asks for location permission. In system settings -> apps -> permissions, ulogger doesn't have GPS permission.

Expected behavior:
A popup should ask for coarse + fine location permission.

I don't mind ulogger in my notifications area but don't particularly want it there all the time.

Please post dash address so I can tip. Thank you.

Thank you very much for ulogger on F-Droid!

I wonder if ulogger could automatically start again logging the current track after an update. At the moment this track has to be started manually after every update. Autostart is activated already, but doesn't work if the phone is not rebooted.

Thank you in advance!

Hi,

Is it possible to hide the notification icon? i would like to use this app as a Find my device alternative, but the notification would be asking for the thief to disable the network connectivity (well, a smart thief would do that as soon as they grab the phone... but yea :D)

Hello.

ulogger keeps crashing on automatic logging on startup.

To reproduce:

Install ulogger.

Enter the following settings:

username filled in
password filled in
server url filled in
Live synchronization ticked
Auto start ticked
Other settings probably don't matter.

Android settings for app:
Battery optimisation: Not optimised
Grant location and storage permissions in Android settings.

Reboot device.

ulogger will start but will fail to log anything to server. Opening the app from the notification (if it stays open, it may disappear) will cause the app to close and will trigger a "ulogger keeps crashing" message from Android.

Workaround:
Press "NEW TRACK" button. Acknowledge warning about deleting data from ulogger (which may or may not show). Press submit to accept default name (in my case Auto_2018.12.09_22.05.12). Don't press "START"

Reboot device.

ulogger will now start logging and will not crash. Persistent notification is also shown and data is sent to the web server. However it will always log to the track name given in the workaround step (Auto_2018.12.09_22.05.12). New tracks are not created at each boot.

My feeling is that a new default track name should be created at each instance of automatic logging happening (emulating the user pressing the NEW TRACK button and pressing start), instead of the existing track being appended to.

The crash should obviously be addressed, but I feel a new track name should also be generated at each device boot.

when the server settings are changed to a new server while a track is being recorded,
ulogger will continue trying to log points into the opened track, which will likely either not exist on the new server, or be a different track there.

possible fixes:

• do not allow changing the server settings while a track is being recorded
• force (re?)starting a (new) track on any a server change
• ask the user for confirmation ("it's the same server, just continue" or "(re-)start track"

(see also a related server-side flaw: bfabiszewski/ulogger-server#32 )

in my personal opinion,
requiring a track to be started by the client is sub-optimal anyway.
instead i would just have the server log to the last open track of that user (or not require separating the log into tracks at all).
(that would also allow for implementing #9 on the server-side, for example.)

Hi,
it would be nice to control the start and stop of tracking with a shell command. I'm planning to use this with tasker.

Thank you!

Expected behaviour

The app is supposed to be stable and I should be able to use it properly.

Actual behaviour

But the app crashes on launching disabling users to use the any features.

How to reproduce

1. Install the app from fdroid.
2. Launch the app.
3. The app crashes.

• App version: 2.0
• Device: Samsung Galaxy Tab 3
• Operating system: Android 4.4.2
  (Ps: The app doesn't crash on Android 6.0.1 but crashes in kitkat os.)

Just wondering, its some bug or my phone. Xperia Z5 no signal or bad signal from GPS sensor,
Open->setup settings->new track->start->and nothing
after all night got some signal on the way to work lost again, newer got back.
Any advice?

ULogger should start tracking location on boot when this otion is selected in the settings, but it doesn't. I have to do it manually everytime my device reboots.

Device: Xiaomi MiA1
OS: Lineageos 15.1 (android 8.1.0)
App version: 2.2

Note: start at boot is allowed in privacy guard

Upload to local Server failed with the error message: "Expected literal value at character 0 of /"

Hi,
I've left mulogger run continuously since its release on FDroid, at the 1 minute or 10 seconds refresh intervals. Unfortunately, it records position values only for a fraction of the times it should, especially when the phone is not in use.

I've already ruled out filtering (minimum accuracy, minimum movment etc) -- because all measurements are much better than 5km in my area and I left the phone at home. Disabling automatic battery optimizations made things worse on the one night I tried.

I believe this is the same as the known, difficult problem caused by overzealous power management. Tiny Travel Tracker might give plenty of inspirations what solutions do not work. On the other hand, GPX recording by the Osmand plugin has never failed me, but it is also very heavy on the battery.

Attached is the database dump of time stamps. Please let me know what you'd need from the logfiles -- I'd prefer not to publish everything from a very long time span (and audit it for sensitive information beforehand).

Thank you, it feels great to work with a responsive developer, even if I'm just a lowly bug-reporter.

ulogger.db.txt

Version info, everything from FDroid: ulogger 1.0 and 1.1 (upgraded as soon as published). MicroG 0.2.4 stable, backends LocalGsmNlpBackend + LocalWifiNlpBackend + OpenBmapNlpBackend current stable versions with current offline database.
Android 6.0.1 slimrom. Latest XPrivacy and XPosed, no restrictions on ulogger.

It would be great to be able to have an option to enable an automatic feature that only sends the location when the phone gets low on battery. To not get to heavy on the battery, maybe there could be some options for only one location update, or on a slow interval.
This could also be achived by tasker integration with start / stop record location? (but probably heavier on battery?)
Thanks for the great program. Is there anyway to donate?

Edit:
Now when i think about it. It would be awesome to have tasker integration. Then you could for example send a specific text to trigger "record location". If the phone is lost or stolen.

I've tried to install you app in my wife phone, but F-droid report that version 1.0 is installed, claim there's an incompatible key and, even if i enable ''incompatible versions'' there's no way to uninstall it (and so upgrade it).

If i list installed Apps, there's no such app, even enabling ''system'' app view.

Clearly phone is NOT rooted. Some hint? Thanks.

Hi,

Thanks for this very useful app! I am using it to log to phonetrack-oc app on my Nextcloud! :) My goal is to have a basic app running in the background and logging 24/7 (with quite large interval, maybe an hour).

I discovered that in the app, there is a setting to choose location source (GPS, network or both). But this setting is also present in Android itself (I can choose between high precision, or battery saving which is basically the same setting).

I was expecting I could set the uLogger setting to "GPS and network" and it would default to whatever is available. This way, I could keep it running in background and switch location mode / disable location and uLogger would cope with it, trying to find the best source for each point and not logging if location is disabled (within a same track). But actually, it seems this is not the case and I have to match the system setting with the uLogger setting :/

Thanks!

I'm thinking about using uLogger for tracking my bike rides. One vital feature I'd need for that would be auto-pause when stopping.

Are there any plans implementing that?

I've tried to run uLogger on two mobiles with Android 9 (Moto X4, Nokia 7 plus), and application crashes, after click on "Start".
The same configuration works fine on Android 8 (Moto G6 play).
On Android 9, uLogger don't asks for permitions, but setting them manually doesn't help.

Hi,
I hope this is the right place for this.

I have used OwnTracks in the past, but it requires Google Play Services, which I'm happy to have gotten rid of on my phone. Hence, I'm looking for a replacement.
Is there a way to make µlogger communicate with my MQTT broker?
(preferably without the server counterpart, but if inavoidable I'd jump through the hoops necessary to go via the µlogger server to MQTT)

Ulogger cannot export a track as a gpx file once it reaches around a million data points. It simply hangs and gives no error message.

I use ulogger as an always-on, completely-offline GPS/NLP tracker for privacy reasons. There is no way to start a new track (since that would delete all previous data), so I'm stuck pushing everything into one single track. Over time, it has grown to over a million data points.

The workaround is to open an Oandbackup backup of the app database on the desktop with an sqlite editor.

Maybe some database code could be lifted from Tiny Travel Tracker? It is designed to handle that many data points.

This project is very nice, but have much duplicate code because no have one lib like Timber to manager logs

example:
this code

 if (Logger.DEBUG) { Log.d(TAG, "[onResume]"); }

will be:

Timber.d(TAG, "[onResume]");

Server URL dont accept local server addresses, such as http://myserver/rec

This is required if the server should be accessable only from internal net (via vpn connection).

Hey Mate!
Do you or anyone else happen to know of an iOS alternative that will achieve the same as this app with the ulogger server?
Cheers!

Is it possible to get battery status and send it to server?

F-Droid is reporting with the 2.4 release that you are requesting new permissions. I am uncertain if they are truly new or in error.

Hi,

It would be nice if the App would request GPS position dynamic with higer frequency if I move or request it if the WLAN/GSM Net is changed. If I don't move the requests could be less often.

So I would have a more exact Tracking and Battery save if I sleep oder when I'm at Work. Currently the App polls every 1m for a new Position

When I tap the upload button I get HTTP error code: 400 under the synchronization section. When I tap it again I get this:
Value <html><body><script of type java.lang.String cannot be converted to JSONObject

I get the following error, and I'm fairly sure it's because I'm using a self-signed certificate. I would like the app to ask me if I want to accept it or not.

Thanks

java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

Currently, only live updates are supported, i.e. the location is uploaded as soon as it is acquired and logged.

A more battery-friendly behavior would be uploading locations in batches if live sync is not necessary.

A batch upload may have a few conditions:

• minimal time between syncs
• minimal number of updates in a sync
• maximum time between syncs
• maximal number of updates in a sync

and maybe a few others, I'm not sure what trigger logic would be best for an average user. For me it would probably be minimum time between syncs and minimal number of updates in a batch but ymmv.

Hello,

The shortest minimum time allowed by the app is 10 seconds, it would be better if the time was shorter.

To decimate the number of saved trackpoints a very optimal algorithm can be used: The so-called Douglas-Peucker-Algorithm. One imlementation can be found in gpx.c of Project TTTracklog. https://codeberg.org/kollo/TTTracklog/src/branch/master/src/gpx.c
sea function decimate(). Maybe you want to be inspired from this little logger I once wrote for TomTom Navigation devices.

Hi, thank you for your work.

My ulogger server sits behind an nginx webserver with basic access authentication. The only way to use this in the application is to encode it as https://username:password@server. However, the serverlogs show, that the application does not receive the credentials at all.

Could you please enable HTTP Basic auth support?

First let me thank you for the app, and making it open source. I was on the way to create one for myself, I was a long user of TrackeMe (under windows mobile 6, then Android). For some reason, the app can't get any location, I have network cells and gps in the settings, and I have gps enabled. I'm on LOS 13.0 and I noticed that the app did not ask for location permissions, wondering what I'm missing. I don't allow google services to manage my location maybe the issue if you rely on them. Any way to have the application to get gps coordinates itself. Thank you.

I originally posted in this report as a comment. Changed phone and now running Lineage OS 15 (Android 8.1) on a Bq Aquaris X, having previously been on CM13 on another brand. uLogger worked very well previously. Locally stored track matched the one uploaded to server. Now, under Android 8.1 and uLogger, both from this thread and latest from f-droid - battery optimisation off for the app - the uploaded track has just 37 of the 137 locally logged fixes.

So, background logging is not a problem; as it stands now under Android 8.1, background access by uLogger to the data link seems to be an issue.FWIIW, GPSLogger does not display this behaviour.

As the title says.
I have added multiple user accounts to a server for various reasons.
A bug that i've found is that when I change the username of an account, I must either restart the device or force close the app and reopen it for the username change to take effect.
There needs to be some sort of an Apply Changes Button maybe?

If this is not a bug, please do advise :)

Steps to reproduce:
Configure network+GPS location sources. Disallow location permission in system settings -> apps -> ulogger -> permissions. Start recording a new (offline) track.

Observed behavior:
There is no error message whatsoever. No data is recorded.

Expected behavior:
A notification / toast / popup should appear when locating fails for any permanent reason.

Hi, have you ever compared your software to https://gpslogger.app/ ?

Is it possible to use the gpslogger to update your server?

I am asking because gpslogger has slightly better user interface, especially on modern android, it stays on very thin notification area and takes less screen than ulogger.

I see https://developer.android.com/training/articles/security-ssl.html?
It for add to ulogger-android/app/src/main/java/net/fabiszewski/ulogger/WebHelper.java
But I can't see how android app could load '.crt' file. Or it used as string simple.

My idea is use it with raspberry pi as server (I tried letsencrypt.org but not work, then I create autosigned certificate)

Cheers.

Hai, I'm new on programming can you give some tutorial for connecting ulogger server to android ? I have save or install ulogger to my localhost and install ulogger on my android but it doesn't give me anything i'm trying to start and stop the application but still can't detect my location. Can you please help me?

Hi,
would it be possible to make ulogger also read out the GPS / network position whenever another app has already requested the position (and incurred the battery drain)? This would further reduce power usage, because ulogger gets the position once for free and can wait longer until it requests the next location update from the OS.

Role models: This app acquires the GPS position and wifi scan results for free whenever another app initiates the scans:
https://f-droid.org/repository/browse/?fdfilter=backend&fdid=org.fitchfamily.android.wifi_backend

This app aquires the GPS position and displays a notification whenever another app scans for position: https://f-droid.org/repository/browse/?fdfilter=satstat&fdid=com.vonglasow.michael.satstat

Thanks for the great app!

Hi, would you please add (1) a button and (1) a scriptable intent to export all the data fields of the current, non-synced track as a gpx file?

The use case is: completely offline, 24/7, network location tracking. I.e. I'm not using a ulogger server at all. Occasionally, I'd like to view the track in Osmand, or run scripts to figure out when I'm at work etc. (I'm so glad there's finally a location tracker that does not insist on GPS.)

Why that? Offline -> privacy (and easier firewall config). 24/7 -> quantified self. Network location -> battery drain, indoors a lot. No ulogger server -> questions like "look where I took the kids" or "which way is usually faster" typically arise away from the computer (and easier setup).

Version info, everything from FDroid: ulogger 1.0. MicroG 0.2.4 stable, backends LocalGsmNlpBackend + LocalWifiNlpBackend + OpenBmapNlpBackend current stable versions with offline database. Android 6.0.1 Slimrom.

Hi,

I noticed that uLogger has a setting for a minimal distance between points to send an update of position. By lowering the default value (typically to "no minimum"), uLogger suddenly crashes with an Android popup about uLogger crashing and asking whether to open it again or not.

I might be able to pull a logcat log if it can help investigating the issue.

Thanks!

Hi,

i think there is a bug, an @ in the username does not work, when i try to enter that, the application requests a "proper servername" , if i do anything else without @ i have no problem saving it

cheers
