this is my code working in android but not working in ios

The plugin works fine but there is no icon when I run example project. Could you add some customization options for the icon, icon color, text and make "Stop location service" action optional?

Calling setAndroidConfiguration was passing a string to the "set_configuration" methodcall in BackgroundLocationPlugin.kt causing an invalid cast error

The named parameter has also been removed for compatibility with the example

The package does not seem to receive background updates on Android when the emulator's screen is off(I presume the off button on the emulator is simply just the screen being off and not the device).

The package, however, does work well if you have the screen on, the active app is google maps and the app is in the background.

The plugin background_location uses a deprecated version of the Android embedding. To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs. If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

This PR contains the same changes as #101 but also adds an explicit option to force LocationManager on android for users that prefer to not use google play services for location, such as developers looking to publish apps to F-Droid.

This PR includes changes to the README to document the change and some testing has been done in a real app with no apparent issues.

background_location plugin depends on the permission handler 5.0.1+1 version and my other plugin needs to be updated which triggers the conflict with the permission handler version's plugin_platform_interface version. Therefore, I updated the permission handler plugin version. Now, It shows conflict with the background location plugin version as it still depends on the older version of the permission handler plugin version. Is there any kind of work going on regarding this issue? or I have to move on with another plugin to resolve this issue.

As some of you may know, requesting 'ACCESS_BACKGROUND_LOCATION' now requires that you submit for a special approval before your app is allowed on the the Play Store. This is because that permission is only meant to be used if the app needs background location without the user triggering it or when the app is not on screen (and not showing the user it's using the service). If you want location while the app is not in the foreground or screen is off (like a run tracking app) the 'proper' approach is to start a foreground service. That's what this plugin does, however, it relies on the user having their location permission set to 'All the time'. If it's set to 'While the app is in use' it will only get location a few times an hour.

A clear and concise explanation of these recent platform changes is provided here: (https://medium.com/@adrian.kajda/restrictions-to-background-location-and-foreground-services-in-android-11-9501adcd5795).

So for those of us who want to access frequent 'background location' without needing the 'ACCESS_BACKGROUND_LOCATION' permission and all the baggage that comes with it, there is an issue. But there's a fix! I adjusted 2 lines of code in this plugin and it allows for 'background location' access (technically not in the background because it's a service and showing the user a notification) while the app is not in the foreground.

Both changes occur in the plugins Manifest.xml file: Change 1: Remove the 'ACCESS_BACKGROUND_LOCATION' permission. Change 2: Add 'android:foregroundServiceType="location" to the service tag. Like this: <service android:name=".LocationUpdatesService" android:foregroundServiceType="location" android:enabled="true" android:exported="true" android:permission="" />

Setting the 'foregroundServiceType' to 'location' is critical. Without it, the system will not realize that the foreground service is meant for location and will therefore greatly limit any attempts to get location info. Important: In Android 11, you cannot start a foreground service for location in the background so if you use this make sure to start your service before the app is put into the background. If you need that type of functionality, that's what access_background_location is for.

To finish up, I'm not sure if this plugin can be adjusted to allow for both scenarios mentioned above (I suspect not because of the inclusion of the 'ACCESS_BACKGROUND_LOCATION') but I wanted to submit this as an 'issue' just so people are aware. And maybe a better programmer than I am does know how to make it dynamic based on needs. And if not, perhaps it could be duplicated but with those minor changes to cover the 'running app' use case nicely.

And a big thank you to Almoullim for writing this plugin!!! My apologies if this is a totally inappropriate use of submitting an issue!

after trying to install the lib i got this error

I got this error when I added just the backgroud_location: ^0.8.1 package to my project:

 C:\SDK\flutter_sdk\.pub-cache\hosted\pub.dartlang.org\background_location-0.8.1\android\src\main\kotlin\com\almoullim\background_location\BackgroundLocationService.kt: (23, 1): Class 'BackgroundLocationService' is not abstract and does not implement abstract member public abstract fun onRequestPermissionsResult(p0: Int, p1: Array<(out) String!>, p2: IntArray): Boolean defined in io.flutter.plugin.common.PluginRegistry.RequestPermissionsResultListener

It is good to have a durationFiltee similar to distanceFilter in method startLocationService. Sometimes it is necessary to track geo position using not distance but duration (or even both of them).

I'm considering to use this package in an app, so I was reading thought the issues.

Problem

I found two issues concerning notification importance

• https://github.com/Almoullim/background_location/issues/147
• https://github.com/Almoullim/background_location/issues/96

The subject of these issues is the fact that notification importance is currently set to low, which is not desirable as the system may not show, or hide the notification after a while: https://github.com/Almoullim/background_location/blob/6756c7c974721d5c2bf6894f04f20d2e08dc31b2/android/src/main/kotlin/com/almoullim/background_location/LocationUpdatesService.kt#L134

Solution

In issue https://github.com/Almoullim/background_location/issues/96 the author mentions a fork of this repository in which he implemented a fix. It can be seen in this commit:

The changes can be seen here:

https://github.com/willhaslett/background_location_important/commit/45797a7082c84910544cb0b99e239e3566cfee31

It's basically changing NotificationManager.IMPORTANCE_LOW to NotificationManager.IMPORTANCE_DEFAULT.

Can you please also implement it this in this repository?
