Android Question Problems with sending location when the app is in the background (FusedLocationProvider)

[jose luis gudino]

Hello everyone.
I have a query that worries me.

Which is the exact way to send the location while in the background. In previous times, sending the location was extremely simple. Now I haven't made it.

I used a phone with an old version of android 9 and it worked perfectly. install the same program on a phone with android 11, and it stopped working.

My question is: may or may not send in the background at present?. I have done all the examples and I do not get the solution

Thank you all

Background location tracking

Simple example of a foreground service that keeps the process running in the background. The current location is shown in the persistent notification. The app starts at boot and theoretically should run all the time. It also schedules itself to run with StartServiceAt. This can help in cases...

Not sure if it still a working solution. I read often about the same problem. You need to try

Android is more restrictive with every update.
In the DonManfred link you have this advice, have you do this?

There is a new requirement in Android 10+ devices.
In order for the location tracking to continue working in the background, if the user chooses the "allow while app is open" permission option we need to add this line to the manifest editor:

SetServiceAttribute(Tracker, android:foregroundServiceType, "location")

Yes,
You should read the new restrictions and procedures to follow on the Android developer website.

Hello, thanks for your contribution . I already tried it. but unfortunately it didn't work

Android es más restrictivo con cada actualización.
En el enlace de DonManfred tienes este consejo, ¿has hecho esto?

Hay un nuevo requisito en los dispositivos Android 10+.
Para que el seguimiento de ubicación continúe funcionando en segundo plano, si el usuario elige la opción de permiso "permitir mientras la aplicación está abierta", debemos agregar esta línea al editor de manifiesto:
[código]
SetServiceAttribute(Tracker, android:foregroundServiceType, "ubicación")
[/código]

Thanks jose, I've already tried it and nothing. It's like it stopped working.
As I mentioned before, on a phone with android version 9 it works perfectly, I have even written that in the manifest and nothing does not work

 

[jose luis gudino]

Hi.
I would really like to know if this is already a definite android restriction or if there is a solution.
to see which option to take.

I remember there is a very helpful thread from a forum member where he was testing a lot of things with services and differents versions of android, but I can't find it. Maybe was @Sandman or @Mahares ? Not sure.

Anyway, if you test some apps that runs in background for long time, now it shows you some tips before redirecting you to the permission settings (i.e. Ignore app from battery optimization, etc...)

Some post maybe helpful:

Hi guys, I runs this example on my phone : Android 9, EMUI 9.1, B4A 9.8 https://www.b4x.com/android/forum/threads/background-location-tracking.99873/#content The app is suppose to runs forever but in my case, when phone slept for a few minutes, OS killed it. I changed the codes at service...

About runtime permission

Just a confirmation if I'm doing correctly: I have declared in "configure paths" the android-23 platform. This because I want to manage a runtime permission in Android 6 and force the user to exclude the App from the battery optimization Sub Activity_Resume If GetAndroidApiLevel>=23 Then...

Jose, super grateful, for your time and for your interest in helping me solve this problem that is serious for me, since I have an app which is very important to use location sending in the background, I will read the information and I tell you if it works for me

Nothing!, it did not work, I think that this topic is more complex than we think

 

[TILogistic]

Can you tell us about the process you use to capture the GPS location in the background (FusedLocationProvider)?

I have read the links you recommend?
another and watch the video

Have you tried to set "No restrictions" to the Battery optimization of the app?
Something like

 

[edgar_ortiz]

Hi,

Its works... its NOT a NICE code have a lot "test" code.

Does NOT work for next day scheduling, when user force close the app.

I'm very busy and I hope someone put it in a decent way

Regards

Edgar

Hello TILogistic, thanks for providing a possible solution to the problem. Yes indeed, I use FusedLocationProvider.
I have removed all the code and I have left only the base code (the one that appears in the demos in its most recent version of FusedLocationProvider)
but nothing, I remember that the same code had been working for me for a year without any problem. but from a while ago it didn't work anymore.

I have already tried this option and it does not work: the problem is basically: We have a service which records the location, the problem is that when calling "waze" in an intent ,the application goes to the background and immediately stops send position, when closing waze and returning to the foreground once it starts sending correctly

 

[jose luis gudino]

I explain in more detail:
the problem is basically: We have a service which records the location perfectly, the problem is that when calling "waze" in an INTENT the application goes to the background and immediately stops sending position, when closing waze and resume the foreground once starts sending successfully
