Location is not updated with Google services disabled

[Atrate]

Device info: OS: DivestOS 19, Android 12 Location services: GPS only, no GNSS/Wifi App version: 0.3.0 from Google Play

Problem description:

After I upgraded my phone from A11 to A12, ED can't seem to get a location lock. Wiping application data makes ED get one lock, but no more than that, no matter how many times the app is restarted.

Everything worked without a problem on Android 11.

Other GPS-using apps work well, such as OSMAnd.

I can provide a logcat capture if that's useful.

Possibly related to #106.

Does not seem to be fixed in 0.4, from my testing.

[Zverik]

Thanks Atrate. I guess I'll replace the geolocation library for 0.5.

A workaround is to force another application to use GNSS in the background, for example, record a track in Osmand.

Must be fixed in 0.9, please check.

Looks like this all is an upstream issue:

• https://github.com/Baseflow/flutter-geolocator/issues/1114
• https://github.com/Baseflow/flutter-geolocator/issues/1027
• https://github.com/Baseflow/flutter-geolocator/issues/667
• https://github.com/Baseflow/flutter-geolocator/issues/507

I might have to change the library.

Not fixed, unfortunately

Hi from Ecuador, We're facing the same issue. We are waiting for a fix on this, thanks in advance.

Progress report: last weekend I:

1. Confirmed that GPS does not work in the geolocator_android library (that I'm using) versions 3.0.4, 3.1.8, 4.0.2. I could not build 2.1.0, but it's too old anyway.
2. Rewrote geolocation to the location library version 4.4.0. Raw GPS still does not work, and it seems that version was built around Google services. But with Google services, location updates are more frequent than before. Will try 5.0.0-dev.8.
3. Tried to find a third geolocation library, failed.

I have a suspicion that there's something wrong with my location flow or library dependencies. Will also try building a minimal app to test these two libraries from the scratch.

Tried to find a third geolocation library, failed.

@Zverik what about using a library that StreetComplete or Vespucci or OSMand use? They work fine without Google.

[Zverik]

I would love to use their solutions, but all of these are native Android apps, while Every Door was written in Dart / Flutter. But maybe I could use something in the android part of the geolocation library.

[Zverik]

Okay, I give up for now. This requires a lot of in-depth knowledge of Android geolocation programming. I welcome any help with this source code.

For a bypass, I'm doing #281 and #453.

That's pity, I really like the app after trying it for the first time today, but have to kill it all the time to get new location. LOS 19.1 without any gapps.

[Zverik]

If anybody finds a Flutter-based app with geolocation that works without Google services, I could use that as well. To me it seems like every location library is broken. On the positive side, it concerns only Android 12+.

Hi Ilya I have briefly discussed this in small matrix community and they had some ideas about code, if you'd like to join you're all welcomed at https://matrix.to/#/#flutter-devs:matrix.org

disclaimer: I myself am not a dev, just user.

I think installing https://github.com/microg/FakeStore fixed the issue for some reason? I do not have microg installed, though, so it's quite weird, maybe an Android update fixed it instead?

[Zverik]

Looks like it was fixed! (see 4.0 beta)
