infinite repeat backgroundCallback when First time only install app for any device android

[AhkamKhallaf]

when BackgroundLocationTrackerManager.handleBackgroundUpdated is called ,
i call api request to save this new location to server , but this request is repeated many times ,
how cal fix this bug

@pragma('vm:entry-point')
void backgroundCallback() {
  BackgroundLocationTrackerManager.handleBackgroundUpdated(
      (BackgroundLocationUpdateData data) async {
    await providerContainer.read(currentLocationApiProvider).saveUserLocation(data);
  });
}

final Provider<CurrentLocationApi> currentLocationApiProvider = Provider<CurrentLocationApi>(
        (ProviderRef<CurrentLocationApi> ref) => CurrentLocationApi(ref.read));

class CurrentLocationApi {
  final Reader read;

  CurrentLocationApi(this.read);

  Preferences get preferences => read(preferencesProvider);

  ApiCore get apiCore => read(apiCoreProvider);

  Future<void> saveUserLocation(
      BackgroundLocationUpdateData data,
      ) async {
    await preferences.init();
    apiCore.init();
    try {
      await read(userApiProvider).saveUserLocation(data);
    } catch (onError) {
      debugPrint('$onError,,onError');
    }
  }
}

i use river pod as state management @vanlooverenkoen

What do you exactly mean? The api call will be triggered every time the location updates so this is to be expected

[vanlooverenkoen]

On Android/iOS?

On Android/iOS

android
such as OPPO A31 ANDROID , SAMSUNG 172 ANDROID

The trackingInterval option actually does not work properly In my emulator which is built with A30, A33
and also on Samsung Galaxy S10(SM G977N) too. if the tracking altitude is not required in your project, geoloactor + flutter_background_service could be a good alternative option it has Stream event and you can adjust it's interval by rxDart throttleTime.

@AhkamKhalaaf Do you do WidgetsFlutterBinding.ensureInitialized(); before the await BackgroundLocationTrackerManager.initialize?

@AhkamKhalaaf Do you do WidgetsFlutterBinding.ensureInitialized(); before the await BackgroundLocationTrackerManager.initialize?

yes , i do

[ikbendewilliam]

Have you tried running the example project? Do you also encounter it then?

[AhkamKhallaf]

Have you tried running the example project? Do you also encounter it then?

yes , it's also, there is the same problem

[vanlooverenkoen]

When exactly do you have this issue?

• Only when the app is installed for the first time?
• With every clean install?
• Everytime
• Only when the device in restarted?

[AhkamKhallaf]

• With every clean install?

With every clean install

[vanlooverenkoen]

Just for my understanding:

• clean install
• open app
• start tracking
• ISSUE HAPPENS
• quit app
• stop tracking
• open app
• start tracking
• everything works

Are these steps correct?

[AhkamKhallaf]

• With every clean install?

With every clean install

i note , now , it does not work with the example project, and not with my project
