ichnaeanlpbackend's Issues

Does crash in Android 6.0.1

Your backend does crash in Android 6.0.1 (OmniROM and CopperheadOS).

I get no location information at all. I use a hammerhead (Nexus 5) device.

Exception if location permission is missing on Android 6

Hi, just a note if other people are looking for the same problem. The app force closes if the location permission is missing on Android 6 with the following exception:

01-14 13:14:50.510 15391 15391 E AndroidRuntime: FATAL EXCEPTION: main
01-14 13:14:50.510 15391 15391 E AndroidRuntime: Process: org.microg.nlp.backend.ichnaea, PID: 15391

It's just displaying a common error in the GUI, but works if the location permission is granted manually. Nice would be a dialogue I guess, but a simple toast message that leads in the right direction may also be enough.

System crashing after fetch attempts happen

When using the Mozilla backend for UnifiedNlp on Lineage+microG I get a reboot. I am currently not able to reproduce this crash extremely reliably but it seems to be related to use of Instagram and NewPipe one after another. Here's a snippet from logcat:

Ichnaea not fetching cells

Hi,

I'm trying to get UnifiedNlp to work on my phone running Android 4.2.2. With wifi, everything is working fine with either this backend or the AppleWifi backend. However, it seems that using wifi networks for location positionning under Android 4.2.2 requires having the wifi always on, so I'm looking for a way to rely on cell network.

Using cell network in this backend, I don't get any position. After investigating it a bit in adb logcat, this line always log "Cells: 0" which seems to mean it is not fetching the nearby cells. Not sure why :/

Thanks

Permissions not being granted

I am having trouble getting this back-end to work. I have looked through logcat when running satstat and the only references to "Ichnaea" i have are as follows:

W PackageManager: Not granting permission android.permission.ACCESS_COARSE_LOCATION to package org.microg.nlp.backend.ichnaea because it was previously installed without
W PackageManager: Not granting permission android.permission.ACCESS_FINE_LOCATION to package
W PackageManager: Not granting permission android.permission.READ_PHONE_STATE to package org.microg.nlp.backend.ichnaea because it was previously installed without
I ActivityManager: Start proc 8497:org.microg.nlp.backend.ichnaea/u0a54 for service org.microg.nlp.backend.ichnaea/.BackendService

How can I grant the app the permissions it needs?

missing PEERS_MAC_ADDRESS permission

when using the IchnaeaNlpBackend on android 11 it throws the following error

F-Droid report DisabledAlgorithm and KnownVuln

In this page it report these:

DisabledAlgorithm

This APK was signed using a signature algorithm that was disabled because it is broken.
Since April 2017, APK signatures that use MD5 are no longer considered valid, jarsigner and apksigner will return an error when verifying.

KnownVuln

This APK has a known security vulnerability, found by one of the scanners in fdroidserver.
current APK has a weak MD5 signature aka AntiFeature:DisabledAlgorithm
fix by making new release or rebuild to get an APK signed with the current signature algorithms
uses a version of OpenSSL that has known vulnerabilities
update the app to OpenSSL 1.0.2f/1.0.1r or higher. For more info, see How to address OpenSSL vulnerabilities in your apps

It would be nice to fix them.

Doesn't request background location permission in Android 10

In Android 10, a new location permission was introduced. Therefore, apps have to request android.permission.ACCESS_BACKGROUND_LOCATION in order to access location when running in background. Manually allowing the backend to access background location via local terminal doesn't seem to work.

01-11 17:19:49.047 3493 7691 E WifiService: Permission violation - startScan not allowed for uid=10163, packageName=org.microg.nlp.backend.ichnaea, reason=java.lang.SecurityException: UID 10163 has no location permission

A workaround is proposed by adding this permission to the AndroidManifest.xml:

microg/GmsCore#986

Occasionally freezing

The plugin is occasionally freezing and when this happens the location can no more be determined in any app. The logcat doesn't give useful hints. Reinstalling does not help either. Someone else ?

Does it interfer with MozStumbler

Hello, I've been using your backend for a week now and I have a question:

I've been using Mozstumbler to help Mozilla Location Service and now that I use your backend I wonder it simply does the same thing as Mozstumbler does ?
If it does I can uninstall Mozstumbler because it would be pointless to have it if your backend does the same job isn't it ?

Thanks

Doesn't work well in 2G/3G

Hello,

I don't know if it's UnifiedNlp or IchnaeaNlpBackend that doesn't work well but often my map apps can't find my location. I meant that doesn't work well with GPS disabled (disabled or in buildings). With GPS the location is found quickly. When GPS is not available UnifiedNLP should locate me, not accurately but I think in a range of 100m to 1km based on wifi and gsm, and that often not the case.

Sometimes the location is never found
Sometimes the location is quite imprecise (200+ km radius)
Sometimes the location is wrong, not updated, and correspond to the location where the last time I used the map apps

By the way I live in Bordeaux, France and there is plenty of wifi and 2G, 3G around. The thing is that at a given location sometimes that work, sometimes not.

Thanks !

Android 11 requires permanent location permission

To Reproduce
Steps to reproduce the behavior:

Install Mozilla Location backend
Activate it in MicroG
Configure it
Android requests location permission, but doesn't allow permanent location ; only while the app is running"
No network location is shown in troubleshooting apps such as SatStat

Stop pointing to Mozilla Stumbler

Describe the bug
Currently, this backend points out to Mozilla Stumber as something people can use to help out Mozilla's database.
However, that application was "retired" last February: https://discourse.mozilla.org/t/retiring-mozilla-stumbler/75206 .
As that announcement points out, https://github.com/zamojski/TowerCollector can be used as an alternative to contribute with
submiting cell towers to MLS, we can either just take out that section or point to TowerCollector instead.

Wifi throttling needs to be disabled

I needed to disable wifi throttling in the dev options to make this backend work. Else WifiService refuses to scan completely and the position is not passed on:

06-07 23:39:17.240  1293  1909 I WifiService: startScan uid=10181
06-07 23:39:17.242  1293  2037 I WifiScanRequestProxy: Scan request from org.microg.nlp.backend.ichnaea throttled
06-07 23:39:17.242  1293  1909 E WifiService: Failed to start scan
06-07 23:39:17.250  5276  5276 D BackendHelper: No change in WiFi networks

This is unpleasant, this should work out of the box.

Build failed on F-Droid

Seems that there is an error on the version

Git checkout of 'vv1.3.1' failed

detail begin
error: pathspec 'vv1.3.1' did not match any file(s) known to git.

detail end

https://f-droid.org/wiki/page/org.microg.nlp.backend.ichnaea/lastbuild_20017

Add caching

Similar to the Apple Nlp backend, this backend should probably cache location results. This would improve data usage, responsiveness and privacy.

Contribute Data disables Location Service

I've installed your backend from F-Droid, backend is up to date. This afternoon I wanted to enable the "contribute data" option but when I enable it the backend does not working after. Tried to disable the option it works great again.....

Don't know how to provide a logcat or anything else but would be happy to help

Galaxy S(1) + Omni Rom 4.4.4 + IchnaeNlpBackend KO with cell but OK with WIFI

Hello,
I have some problem with this configuration. Also the tool Mozilla Stumbler doesn't work.
I used the last apk from F-droid and the release version of Omni Rom.
I saw some logcat but there is no information to understand the issue ...

For information, LocalGsmNlpBackend works with a database celldb.

If you have any test to make or tips, it will be greatfull.

Best regards,
Wark.

Crashes when selected in UnifiedNlp settings

ROM: CM-13.0-20160325-NIGHTLY-jfltexx

Using the XposedUnifiedNlp module and UnifiedNlp (v1.6.2-dirty) I can successfully access and configure the settings of the Mozilla Location services backend, but when I go (back) to the UnifiedNlp settings, activate this backend and click "ok" the default Android crash message is shown.

Backend doesn't work with UMTS and LTE

Hello,

I describe the problem. I use the backend with radio GSM and here it works perfect, after them i test UMTS and LTE.
UMTS can only be locate via the Location Area Code and LTE via the Mobile Country Code.
The cellids exists all in the database and the GSM Location Backend works offline perfect.
I use a Moto G.

No location provided (how to debug)

Unfortunately I can't get the location backend to work and I'm a bit lost to find the reason. I've installed the latest UnifiedNlp (GAPPS Version, since I've playstore installed), the XposedUnifiedNlp Module and the IchnaeaNlpBackend 1.4.0 configured and activated. According to the SelfTest everything is in order and should work but "No UnifiedNlp location was provided by the system within 10 seconds".

Now I'm a bit lost on how to find the problem. There is no error message and logcat doesn't show any related errors. Are there any other ways to debug this problem? Or is this a known behaviour?

Im using Lineage 16.0 on an Sony Xperia XZ1Compact

add option to temporarily turn on WiFi when location is requested

It would be convenient to add an option to automatically and temporarily turn on the WiFi radio when location is requested if the WiFi radio was off at the time of the request. I normally keep my WiFi radio off to save battery, but have to activate it for location.

Error:(37, 0) Process 'command 'git'' finished with non-zero exit value 128

Thank you!

Thank you for your project and software!

Thank you for maintenance in the past and in the future!

Kind regards and season's greetings!

Offline data base possible ?

Hello

First thanks for your amazing work !!!

I found that only official backend are working (from microg) all other alternatives does not seems to work.

Any way is it possible to use/create an offline data base like "LocalGsmNlpBackend" is supposed to do ?

Thanks

"No instance found active" in first several runs

I refer to this post for a background, especially a filtered logcat.

MozillaNlpBackend version 1.4.0 with microG version 0.2.8.17785-4 (06c8b76)

When Mozilla Nlp backend is (firstly) enabled in UnifiedNlp, there are messages in logcat: IchnaeaBackendService: No instance found active. The backend gives the location only after a long period and maybe the repeated re-enablings are also necessary.

After searching in codes, I found that the only place to print this message is in the member function reloadInstanceSettings() when instance == null. Note that

instance is a private static variable which is written only by protected member functions onOpen() and onClose(), as far as I understand.
reloadInstanceSettings() is a public member function. However, among member functions, only onCreate() calls it.

This seems to be illogical. The instance could only be set to a non-null value by onOpen(). That is to say, every call to onCreate() would have failed with No instance found active. before the first call of onOpen() - this is a plausible reason why Ichnaea does not work once enabled in UnifiedNlp. Other backends do not share a similar issue under the same circumstance. Especially if we compare the code onCreate() here and that in Apple WiFi Nlp Backend, we see that onCreate() there does not check any analog of instance.

GPS is stuck at my old place

Describe the bug
I moved to another place. but since I also moved my computer and all my devices, also the wifi is called the same (tough it's not the same router anymore).
Now, living here for half a year, I was annoyed by the GPS always showing my old home location with pretty good accuracy. Checked out microG location Modules and the Mozilla Location Service seems to be quite certain that my actual location is... well... 470km away. all the other nlp services I used didn't find anything, so when disabling Mozilla Location Service, there is no GPS at all (at least inside my appartment).

Screenshots

Additional context

[com.mercadopago.wallet] Google's ML Kit for codebar scanning causes crash

App name
Name: Mercado Pago
Package id: com.mercadopago.wallet
Link

Describe the bug
When attempting to use the qrscanner from the app, it crashes instantly and without fault. The log points towards Google's ML Kit's barcode scanner, part of G Play Services, which, as I don't have it, would assumingly be the cause of the crash.

To Reproduce
Steps to reproduce the behavior:

Open the app
Click on 'QR Scan' at the bottom
Crash

Expected behavior
What should happen is that the app would open a qrcode scanner, as it used to, but later versions seem to have implemented this new API.

Cannot enable on Android Nougat

I get a toast message with "Error initializing backend" when I try to enable this service.

logcat:

07-25 20:01:31.424  4579 23414 W ActivityManager: Permission Denial: Accessing service ComponentInfo{org.microg.nlp.backend.ichnaea/org.microg.nlp.backend.ichnaea.BackendService} from pid=30863, uid=10037 requires android.permission.ACCESS_COARSE_LOCATION

Looks like we need to request permissions?

Google play won't downloed

Not compatible with Android 4.1 and below?

Though the F-Droid repo points out this backend should work on Android 2.3.3+, and according to the map my area is covered with a bunch of WiFi APs in the Mozilla database, I couldn't get it to work on my 4.1 device: it returns no location. A closer look with logcat (see this pastebin) suggests something here requires at least Android 4.2. Excerpt:

W/NlpLocationBackendHelper( 8976): java.lang.IllegalStateException: Requires Android 4.2+

Unbinding from: Intent { act=org.microg.nlp.LOCATION_BACKEND pkg=org.microg.nlp.backend.ichnaea cmp=org.microg.nlp.backend.ichnaea/.BackendService }

I had tried two other backends before (OpenBmap and Apple) which didn't work either (my area seems not to be covered in their databases), but this error only showed up when I added Ichnaea.

Any clues?

Note: The device is a tablet running Android 4.1.2. There are no newer Android versions available for it (neither stock nor custom ROMs), so I can't do anything from that end. And it has no GSM nor GPS, so my only choices are location services based on WiFi, so I'm currently stuck with these 3 of which none seems to work.

Android 10 / LOS 17.1: Requests location every 60 seconds

Hi. I'm using Lineage OS for MicroG 17.1:

The Mozilla UnifiedNLP requests the location every 60 seconds if I enable location services. It shows the GPS icon for a few seconds and this repeats every minute.

In the location settings I figured out that the requests are made by Mozilla UnifiedNLP.

The behavior stops if I allow the location permission only if in foreground, but, unfortunately, the NLP stops working at all then.

What can I do to debug this issue?

persistant notification issue.

In recent versions of this app, whenever it is enabled in mgUnifiedNlp app, there is a persistant notification that says to contribute to mozilla location services.

In previous versions of this app, there used to be an option whether or not to contribute to Mozilla Location Services with name defaulted to "mgUser". But now there is no such option and there is a persistant notification on status bar and lockscreen that says to contribute to mozLocService.

Sure i can go to app info and uncheck "show notifications" for this app. But that is not a good solution.

Please fix this..

IchnaeaBackend Version: 1.1.0
android version: 5.0.2
unified nlp version: 1.3.0

Sync names

On GitHub the project name is IchnaeaNlpBackend
On GitHub the apk name is IchnaeaNlpBackend.apk
On F-Droid the name is MozillaNlpBackend
Under Android backends list in UnifiedNlp it appears as Mozilla Location Service

I think it would be better to choose one and rename all of them to the selected name to reduce confusion.

My proposal is to rename in F-Droid to IchnaeaNlpBackend and to change text under Android backends list to simply Ichnaea since there is already the description that refer to Mozilla and the title that refer to location backends.

I'm not sure if it's working correctly

Hi!! 😃

I've installed Networklocation.apk and IchnaeaNlpBackend in my Meizu MX3 as you explain in the main Readme doc. But I'm not sure if it works correctly, let me explain, I hope you will understand me because English it's not my language. Apologizes…

First of all, before installing the apk and the backend I was sure that the phone couldn't locate me by wifi/3G. Then installed Networklocation.apk plus IchnaeaNlpBackend and started the testings. What I did:

1.- In my office the phone located me correctly by wifi. Then, I turned off wifi and turned on the 3G connection. I'd checked the position and I was still in the same place.
2.- After, when I arrived at home I connected the phone to my wifi, I live in another city 20 kms far from my work. I refreshed some apps which use the location service and still appeared to be in work.
3.- Then I installed AppleWifiNlpBackend, checked again and then the apps showed me the correct location, at home.
4.- Then, I selected the IchnaeaNlpBackend again, I turned off wifi and turned on data. The location still was on my work, 20 kms far from home.
5.- After, I did the reverse process, turned off data and turned on wifi. IchnaeaNlpBackend located me at the right place.

And now, I really have no idea if it works or not, I'm a non-technical user so I'm really lost… When the backend connects to Mozilla servers? Every determined period of time?

Thank you very much and kind regards!! 😄

V1.5.0 doesn't connect with 3G/4G

Hi,
First thanks a lot for your great work !
I discovered that the 1.5.0 version doesn't work with a mobile connection (3G/4G). It works great with a wifi connection.
It is easy to see this behavoir wih the MylLocation App https://f-droid.org/fr/packages/com.mirfatif.mylocation/ : location data is provided with wifi connection not with 4G.

FYI 1.4.0 works with both.
Regards,

Add dual sim support on dual sim phones for better accuracy.

I'm not sure if this uses both the cell ids in dual sim phones. If not please add support for better accuracy..

Exceptions in log

I am seeing these errors in the log. Doesn't look all correct to me...

Daily limit hit

When I tried to use location service on my phone today I noticed that UnifiedNlp did not work. I was using Mozilla backend so I switched to GSM location service and everything worked again. I then investigated a little more and I found a warning from logcat:

W OkHttpClient: A connection to https://location.services.mozilla.com/ was leaked. Did you forget to close a response body?

So I searched your source code and found the url the backend tries to visit should be https://location.services.mozilla.com/v1/geolocate?key=068ab754-c06b-473d-a1e5-60e7b1a2eb77. When I opened this url in my browser I got this response:

{"error":{"code":403,"message":"You have exceeded your daily limit.","errors":[{"domain":"usageLimits","message":"You have exceeded your daily limit.","reason":"dailyLimitExceeded"}]}}

So apparently there are too many visits to Mozilla's location service using the same API key.

Is there a way to avoid this? For example, let user register for their own keys?

Cell only version

First, I have to applaud the monumental efforts leading up to this point. Having a drop in replacement for Google location services is outstanding. Thank you.

Would it be possible to create a separate version or user configurable setting that only shares and requests information about cells and not wi-fi access points? Given the sensitivity of Wi-fi points I would prefer to use a different backend for those. I am aware of Local GSM Backend and it is useful, but downloading and creating the local database is resource and time intensive.

Questions about widespread deployment

Hi!

I wasn't sure if there was a better place to ask general questions - but is there any data on how widely the microG library is being deployed? We're seeing a lot of traffic on Ichnaea and microG is hitting it's API key rate-limit at Mozilla.

The traffic looks unusual - I think this is probably because of over aggressive querying of the service in the IchnaeaNlpBackend code which spins up a thread everytime onCellChanged() is invoked.

Is there an IRC channel or slack channel where I can ask someone questions?

thanks!

Mismatched versionCode

I see here

versionCode "20025"

but on F-Droid there is

Build:1.3.3,20026

Is it 20025 or 20026 the correct one?

Add setting to define upper request frequency
