flutter_background_geolocation 1.9.3

The most sophisticated background location tracking & geofencing module with battery-conscious motion-detection intelligence for iOS and Android.

CHANGELOG

1.9.3 - 2010-07-16

• No changes from 1.9.2. This version is merely a bump to satisfy pub.dev penalty for placing http urls in README instead of https.

1.9.2 - 2020-07-08

• [Added][Android] New Config option Notification.sticky (default false) for allowing the Android foreground-service notification to be always shown. The default behavior is the only show the notification when the SDK is in the moving state, but Some developers have expressed the need to provide full disclosure to their users when the SDK is enabled, regardless if the device is stationary with location-services OFF.
• [Added] Support for providing a native "beforeInsert" block in iOS AppDelegate.m and Android Application.java / Application.kt. The returned object will be inserted into the SDK's SQLite database and uploaded to your Config.url. iOS AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [GeneratedPluginRegistrant registerWithRegistry:self];
    
    // [OPTIONAL] This block is called before a location is inserted into the background_geolocation SQLite database.
    // - The returned NSDictionary will be inserted.
    // - If you return nil, no record will be inserted.
    TSLocationManager *bgGeo = [TSLocationManager sharedInstance];
    bgGeo.beforeInsertBlock = ^NSDictionary *(TSLocation *tsLocation) {
        CLLocation *location = tsLocation.location;
        
        NSLog(@"[beforeInsertBlock] %@: %@", tsLocation.uuid, location);
        
        // Return a custom schema or nil to cancel SQLite insert.
        return @{
            @"lat": @(location.coordinate.latitude),
            @"lng": @(location.coordinate.longitude),
            @"battery": @{
                @"level": tsLocation.batteryLevel,
                @"is_charging": @(tsLocation.batteryIsCharging)
            }
        };
    };
    
    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

Android Application.java

public class Application  extends FlutterApplication {
    @Override
    public void onCreate() {        
        super.onCreate();

        BackgroundGeolocation.getInstance(this).setBeforeInsertBlock(new TSBeforeInsertBlock() {
            @Override
            public JSONObject onBeforeInsert(TSLocation tsLocation) {
                Location location = tsLocation.getLocation();
                JSONObject json = new JSONObject();
                JSONObject battery = new JSONObject();
                try {
                    json.put("lat", location.getLatitude());
                    json.put("lng", location.getLongitude());
                    
                    battery.put("level", tsLocation.getBatteryLevel());
                    battery.put("is_charging", tsLocation.getBatteryIsCharging());
                    json.put("battery", battery);
                    return json;
                } catch (JSONException e) {
                    e.printStackTrace();
                    return null;
                }
            }
        });
    }
}

1.9.1 - 2020-07-02

• [Fixed][iOS] Geofence EXIT sometimes not firing when using notifyOnDwell.
• [Changed][Android] Refactor geofencing-only mode to not initiate "Infinite Geofencing" when the total number of added geofences is < 99 (the maximum number of simultaneous geofences that can be monitored on Android). This prevents the SDK from periodically requesting location to query "geofences within geofenceProximityRadius". iOS already has this behaviour (where its maximum simultaneous geofences is 19).
• [Fixed][iOS] When using #ready with reset: true (the default), and autoSync: false, the SDK could initiate HTTP service if any records exist within plugin's SQLite database, since reset: true causes autoSync: true for a fraction of a millisecond, initiating the HTTP Service.

1.9.0 - 2020-06-15

• [Fixed][Android] com.android.tools.build:gradle:4.0.0 no longer allows "direct local aar dependencies". The Android Setup now requires a custom maven url to be added to your app's root android/build.gradle:

A new step is required for Android Setup

📂 android/build.gradle:

allprojects {
    repositories {
        google()
        jcenter()
+       maven {
+           // [required] flutter_background_geolocation
+           url "${project(':flutter_background_geolocation').projectDir}/libs"
+       }
+       maven {
+           // [required] background_fetch
+           url "${project(':background_fetch').projectDir}/libs"
+       }
    }
}

You might then clean your android project:

cd android
./gradlew clean

• [Fixed][Android] onConnectivityChange can report incorrect value for enabled when toggling between Wifi Off / Airplane mode.

1.8.0 - 2020-05-28

• [Fixed][Android] onGeofence event-handler fails to be fired when maxRecordsToPersist: 0.
• [Fixed][Android] requestPermission method was always returning AUTHORIZATION_STATUS_ALWAYS even when When in Use was selected.
• [Fixed] insertLocation exception (issue #220)
• [Fixed][iOS] When using disableStopDetection: true with pausesLocationUpdatesAutomatically: true, the CLLocationManagerDelegate didPauseLocationUpdates fired a motionchange with isMoving: true (should be false).
• [Fixed][Android] Fix @UIThread issue executing location error handler on background-thread.
• [Changed][Android] Gradle import tslocationmanager using api instead of implementation in order to allow overriding SDK's AndroidManifest elements (eg: <service> elements).
• [Fixed][iOS] When upgrading from a version previous <1.4.0, if any records exist within plugin's SQLite database, those records could fail to be properly migrated to new schema.
• [Added] New method BackgroundGeolocation.destroyLocation(uuid) for destroying a single location by Location.uuid.
• [Changed] Android library tslocationmanager.aar is now compiled using androidx. For backwards-compatibility with those how haven't migrated to androidX, a reverse-jetified build is included. Usage is detected automatically based upon android.useAndroidX in one's gradle.properties.
• [Fixed] Allow firebase-adapter to validate license flavors on same key (eg: .development, .staging).
• [Fixed][iOS] iOS geofence listeners on onGeofence method could possibly fail to be called when a geofence event causes iOS to re-launch the app in the background (this would not prevent the plugin posting the geofence event to your Config.url, only a failure of the dart onGeofence to be fired).

1.7.3 - 2020-04-14

• [Fixed] [iOS] Bug in Logger methods. Args are received in native side with NSArray, not NSDictionary

1.7.2 - 2020-04-08

• [Added] [Android] Add new Config.motionTriggerDelay (milliseconds) for preventing false-positive triggering of location-tracking (while walking around one's house, for example). If the motion API triggers back to still before motionTriggerDelay expires, triggering to the moving state will be cancelled.
• [Fixed] Address issue with rare reports of iOS crashing with error referencing SOMotionDetector.m.
• [Fixed] Odometer issue with Android/iOS: Do not persist lastOdometerLocation when plugin is disabled.

1.7.1 - 2020-03-20

• [Added] [Android] Add an boolean extra TSLocationManager: true to the launch Intent of the foreground-notification, allowing application developers to determine when their app was launched due to a click on the foreground-notification.
• [Fixed] Authorization bug in refresh-url response-data recursive iterator. Do not recurse into arrays in token-refresh response from server (tokens are not likely to be found there, anyway).
• [Added] iOS Config.showsBackgroundLocationIndicator, a Boolean indicating whether the status bar changes its appearance when an app uses location services in the background.

1.7.0 - 2020-02-21

• [Fixed] iOS bug related to significant-location-changes (SLC) API. In a previous version, the plugin's geofence manager would stop monitoring SLC if the number of added geofences was < the maximum (20) (in order to not show the new iOS 13 dialog reporting background location usage when infinite-geofencing is not required). The background-geolocation SDK uses several CLLocationManager instances and its GeofenceManager maintains its own instance. However, it turns out that when any CLLocationManager instance stops monitoring the SLC API, then ALL instances stop monitoring SLC, which is highly unexpected and undocumented. As a result, the plugin would lose its safety mechanism should the stationary geofence fail to trigger and iOS tracking could fail to start in some circumstances.
• [Fixed] synchronize methods in TSLocationManager to address Android NPE related to buildTSLocation.
• [Fixed] iOS: Bug in accessToken RegExp in Authorization token-refresh handler.

⚠️ Breaking Change: background_fetch:

• [Changed] Reference background_fetch dependency @ 0.5.3 with new iOS 13 BGTaskScheduler API. See Updated iOS Setup.

1.6.1 - 2020-01-17

• [Added] Implement four new RPC commands addGeofence, removeGeofence, addGeofences, removeGeofences. Document available RPC commands in "HttpGuide".

1.6.0 - 2020-01-14

• [Changed] iOS: Prefix FMDB method-names databasePool -> ts_databasePool after reports of apps being falsely rejected by Apple for "private API usage".
• [Fixed] Android: Ensure that location.hasSpeed() before attempting to use it for distanceFilter elasticity calculations. There was a report of a Device returning Nan for speed.
• [Fixed] Android: Do not throttle http requests after http connect failure when configured with maxRecordsToPersist.
• [Fixed] Android: Respect disableLocationAuthorizationAlert for all cases, including getCurrentPosition.
• [Changed] Android: Modify behaviour of geofences-only mode to not periodically request location-updates. Will use a stationary-geofence of radius geofenceProximityRadius/2 as a trigger to re-evaluate geofences in proximity.
• [Changed] Authorization refreshUrl will post as application/x-www-form-urlencoded instead of form/multipart
• [Changed] iOS geofencing mode will not engage Significant Location Changes API when total geofence count <= 18 in order to prevent new iOS 13 "Location summary" popup from showing frequent location access.
• [Fixed] Android: Add hack for older devices to fix "GPS Week Rollover" bug where incorrect timestamp is recorded from GPS (typically where year is older by 20 years).
• [Fixed] When determining geofences within geofenceProximityRadius, add the location.accuracy as a buffer against low-accuracy locations.
• [Changed] Increase default geofenceProximityRadius: 2000.

1.5.0 - 2019-12-18

• [Changed] Upgrade to new Flutter "V2" Plugin API. See Upgrading pre 1.12 Android Projects. No extra steps required for "Android Headless Mode", it's all automatic now.
• [Changed] Modified Android Foreground Service intent to not restart activity on click.

1.4.5 - 2019-12-12

• [Changed] Upgrade iOS CocoaLumberjack dependency to ~>3.6.0 from ~>3.5.0. It seems some other dependency out there is using CocaoLumberjack@3.6.0.
• [Changed] Fixed example app: flutter_map is messed up again. Find another fork that works with lastest flutter api.

1.4.4 - 2019-12-12

• [Fixed] Previous Android version 1.4.3 was corrupted due to two copies of tslocationmanager.aar being deployed.

1.4.3 - 2019-12-09

• Rename folder docs -> help to satisfy dartdoc on pub.dev (API docs were missing).

1.4.2 - 2019-12-03

• [Fixed] iOS crash when launching first time -[__NSDictionaryM setObject:forKey:]: object cannot be nil (key: authorization)'
• [Changed] Remove Android warning In order to enable encryption, you must provide the com.transistorsoft.locationmanager.ENCRYPTION_PASSWORD when using encrypt: false.
• [Fixed] Added headless implementation for geofenceschange event.

1.4.1 - 2019-12-02

• [Fixed] Android bug rendering Authorization.toJson when no Config.authorization defined.

1.4.0 - 2019-12-02

• [Added] New Config.authorization option for automated authorization-token support. If the SDK receives an HTTP response status 401 Unauthorized and you've provided an authorization config, the plugin will automatically send a request to your configured refreshUrl to request a new token. The SDK will take care of adding the required Authorization HTTP header with Bearer accessToken. In the past, one would manage token-refresh by listening to the SDK's onHttp listener for HTTP 401. This can now all be managed by the SDK by providing a Config.authorization.
• [Added] Implemented strong encryption support via Config.encrypt. When enabled, the SDK will encrypt location data in its SQLite datbase, as well as the payload in HTTP requests. See API docs Config.encrypt for more information, including the configuration of encryption password.
• [Added] New JSON Web Token API for the Demo server at http://tracker.transistorsoft.com. It's now easier than ever to configure the plugin to post to the demo server. See API docs Config.transistorAuthorizationToken. The old method using Config.deviceParams is now deprecated.
• [Added] New DeviceInfo module for providing simple device-info (model, manufacturer, version, platform).
• [Removed] The SDK no longer requires the dependency device_info.

1.3.3 - 2019-10-31

• [Added] New HTTP config disableAutoSyncOnCellular. Set true to allow autoSync only when device is connected to Wifi.
• [Changed] Re-factor iOS HTTP Service to be more robust; Replace deprecated NSURLConnection with NSURLSession.

1.3.2 - 2019-10-24

• [Fixed] Resolve Dart analysis warnings related to @deprecated.

1.3.1 - 2019-10-23

• [Fixed] Android NPE

Caused by: java.lang.NullPointerException:
  at com.transistorsoft.locationmanager.service.TrackingService.b (TrackingService.java:172)
  at com.transistorsoft.locationmanager.service.TrackingService.onStartCommand (TrackingService.java:135)

• [Added] new uploadLog feature for uploading logs directly to a server. This is an alternative to emailLog.
• [Changed] Migrated logging methods getLog, destroyLog, emailLog to new Logger module. See docs for more information. Existing log methods on BackgroundGeolocation are now @deprecated.
• [Changed] All logging methods (getLog, emailLog and uploadLog) now accept an optional SQLQuery. Eg:

SQLQuery query = new SQLQuery(
  start: DateTime.parse('2019-10-23 09:00'),
  end: DateTime.parse('2019-10-23 19:00'),
  limit: 1000,
  order: SQLQuery.ORDER_ASC
);

String log = await Logger.getLog(query)
Logger.emailLog('[e-mail]', query);
Logger.uploadLoad('http://your.server.com/logs', query);

1.3.0 - 2019-10-17

• [Fixed] Android: Fixed issue executing #changePace immediately after #start.
• [Fixed] Android: Add guard against NPR in calculateMedianAccuracy
• [Added] Add new Geofencing methods: #getGeofence(identifier) and #geofenceExists(identifier).
• [Fixed] iOS issue using disableMotionActivityUpdates: false with useSignificantChangesOnly: true and reset: true. Plugin will accidentally ask for Motion Permission.
• [Fixed] Resolved a number of Android issues exposed by booting the app in StrictMode. This should definitely help alleviate ANR issues related to Context.startForegroundService.
• [Added] Android now supports disableMotionActivityUpdates for Android 10 which now requires run-time permission for "Physical Activity". Setting to true will not ask user for this permission. The plugin will fallback to using the "stationary geofence" triggering, like iOS.
• [Changed] Android: Ensure all code that accesses the database is performed in background-threads, including all logging (addresses Context.startForegroundService ANR issue).
• [Changed] Android: Ensure all geofence event-handling is performed in background-threads (addresses Context.startForegroundService ANR issue).
• [Added] Android: implement logic to handle operation without Motion API on Android 10. v3 has always used a "stationary geofence" like iOS as a fail-safe, but this is now crucial for Android 10 which now requires run-time permission for "Physical Activity". For those users who [Deny] this permission, Android will trigger tracking in a manner similar to iOS (ie: requiring movement of about 200 meters). This also requires handling to detect when the device has become stationary.

[1.2.4] - 2019-09-20

• [Fixed] flutter@1.9.1 deprecated a method FlutterMain.findBundleAppPath(Context), replacing with a new signature the receives no Context. Changing to the new signature breaks people using < flutter 1.9.1. Will use old signature for now.
• [Fixed] Custom layouts were not working properly for older OS version < O. Custom layout will use setBigContentLayout now. The user will be able to expand the notification to reveal the custom layout.

[1.2.3] - 2019-09-16

• [Changed] Bump background_fetch version to 0.3.0
• [Changed] Android: move more location-handling code into background-threads to help mitigate against ANR referencing Context.startForegroundService
• [Changed] Android: If BackgroundGeolocation adapter is instantiated headless and is enabled, force ActivityRecognitionService to start.
• [Added] Add mock to locationTemplate data.
• [Added] Android now adds 2 extra setup steps. (1) The plugin now hosts its own proguard-rules.pro which must be manually added to app/build.gradle. (2) The plugin now hosts its own custom gradle file which must also be manually apply from in your app/build.gradle. This extra gradle file contains a simple method to strip the SDK's debug sound-effects from your release build (1.5M):

android/app/build.gradle

📂 android/app/build.gradle:

// flutter_background_geolocation
+Project background_geolocation = project(':flutter_background_geolocation')
// 1.  Extra gradle file
+apply from: "${background_geolocation.projectDir}/background_geolocation.gradle"

android {
    .
    .
    .
    buildTypes {
        release {
            .
            .
            .
            minifyEnabled true
            // 2.  background_geolocation requires custom Proguard Rules when used with minifyEnabled
+           proguardFiles "${background_geolocation.projectDir}/proguard-rules.pro"
        }
    }
}

[1.2.2] - 2019-09-05

• [Changed] Rebuild iOS TSLocationManager.framework with XCode 10 (previous build used XCode 11-beta6). Replace @available macro with SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO.
• [Fixed] iOS 13 preventSuspend was not working with iOS 13. iOS has once again decreased the max time for UIApplication beginBackgroundTask from 180s down to 30s.
• [Fixed] Android Geofences.extras not being provided to #onGeofencesChange event (issue #110).
• [Fixed] iOS 10 provides bool attributes as int in State. Check runtimeType == int. Issue #111.
• [Changed] Upgrade android-logback dependency to 2.0.0
• [Changed] Android: move some plugin initialization into background-threads (eg: performLogCleanup) to help mitigate against ANR "Context.startForegroundService did not then call Service.startForeground".

[1.2.1] - 2019-08-22

• [Fixed] Android Initial headless events can be missed when app booted due to motion transition event.
• [Fixed] Android crash with EventBus Subscriber already registered error.
• [Fixed] iOS Crash: [TSHttpService postBatch:error:] + 6335064 (TSHttpService.m:253)

[1.2.0] - 2019-08-17

• [Added] iOS 13 support.

[1.1.0] - 2019-08-07

• [Fixed] Android Geofence DWELL transition (notifyOnDwell: true) not firing.
• [Fixed] iOS logMaxDays was hard-coded to 7; Config option not being respected.
• [Added] Android Q support (API 29) with new location permission model When In Use. Android now supports the config option locationAuthorizationRequest which was traditionally iOS-only. Also, Android Q now requires runtime permission from user for ACTIVITY_RECOGNITION.
• [Changed] Another Android tweak to mitigate against error Context.startForegroundService() did not then call Service.startForeground().
• [Changed] Add new Android gradle config parameter appCompatVersion to replace supportLibVersion for better AndroidX compatibility. If appCompatVersion is not found, the plugin's gradle file falls back to old supportLibVersion.

[1.0.12] - 2019-07-23

• [Fixed] Found a few more cases where Android callbacks are being executed in background-thread. References issue #70.

[1.0.11] - 2019-07-10

• [Fixed] Android issue running enabledchange event in background-thread with flutter 1.7

[1.0.10] - 2019-06-25

• [Fixed] iOS / Android issues with odometer and getCurrentPosition when used with maximumAge constraint. Incorrect, old location was being returned instead of latest available.
• [Fixed] Some Android methods were executing the callback in background-thread, exposed when using flutter dev channel (#insertLocation, #getLocations, #getGeofences, #sync).
• [Fixed] Add intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK) to DeviceSettings request for Android 9 compatibility.
• [Changed] Tweaks to Android services code to help guard against error Context.startForegroundService() did not then call Service.startForeground().
• [Fixed] iOS manual sync crash in simulator while executing callback when error response is returned from server.

[1.0.9] - 2019-06-17

• [Fixed] Android bug with getCurrentPosition and maximumAge, Fixes #80.
• [Fixed] Odometer issues: clear odometer reference location on #stop, #startGeofences.
• [Fixed] Odometer issues: Android must persist its odometer reference location since the foreground-service is no longer long-lived and the app may be terminated between motionchange events.
• [Fixed] Return Service.START_REDELIVER_INTENT from HeartbeatService. Fixes #79 to prevent null Intent being delivered to HeartbeatService.
• [Added] Implement Android LocationSettingsRequest. Determines if device settings is currently configured according to the plugin's desired-settings (eg: gps enabled, location-services enabled). If the device settings differs, an automatic dialog will perform the required settings changes automatically when user clicks [OK].
• [Fixed] Android triggerActivities was not implemented refactor of 1.x.

[1.0.8] - 2019-06-04

• [Fixed] Android destroyLocations callback was being executed in background-thread.
• [Fixed] When Android geofence API receives a GEOFENCE_NOT_AVAILABLE error (can occur is Wifi is disabled), geofences must be re-registered.
• [Fixed] Android Config.disableStopDetection was not implemented.

[1.0.7] - 2019-05-13

• [Fixed] Android issue with Firebase Adapter support not working when app is terminated.

[1.0.6] - 2019-05-12

• [Added] New Android config Config.scheduleUseAlarmManager to force Android scheduler to use more precise AlarmManager instead of JobScheduler.
• [Added] Support for background_geolocation_firebase adapter.

[1.0.5] - 2019-05-10

• [Changed] Rollback android-permissions version back to 0.1.8. It relies on support-annotations@28. This isn't a problem if one simply upgrades their targetSdkVersion but the support calls aren't worth the hassle, since the latest version doesn't offer anything the plugin needs.

[1.0.4] - 2019-05-09

• [Changed] Update docs.

[1.0.3] - 2019-05-08

• [Fixed] Dart analysis warnings, re: initializing null values in new Notification class.

[1.0.2] - 2019-05-08

• [Fixed] iOS: changing pauseslocationUpdatesAutomatically was not being applied.
• [Changed] reset parameter provided to #ready has now been default to true. This causes too many support issues for people using the plugin the first time.
• [Fixed] Android threading issue where 2 distinct SingleLocationRequest were issued the same id. This could result in the foreground service quickly starting/stopping until locationTimeout expired.
• [Fixed] Android issue where geofences could fail to query for new geofences-in-proximity after a restart.
• [Fixed] Android issues re-booting device with location-services disabled or location-authorization revoked.
• [Added] Implement support for Custom Android Notification Layouts.
• [Fixed] Android bug where Service repeatedly stops / starts after rebooting device with plugin in moving state.
• [Fixed] Android scheduler bug. When app is terminated & restarted during a scheduled ON period, tracking-service does not restart.
• [Fixed] Android headless heartbeat events were failing (incorrect Context was supplied to the event).

[1.0.1] - 2019-04-09

• [Fixed] iOS: Incorrect return type BOOL from native method stopBackgroundTask. Should have been int.
• [Changed] Add Geofence test panel in example Settings screen. Allows to add a series of test-geofences along the iOS simulator Freeway Drive route.

[1.0.0] - 2019-04-05

• [RELEASE] Release 1.0.0

[1.0.0-rc.4] - 2019-03-31

• [Fixed] Android: Another NullPointerException with Bundle#getExtras.

[1.0.0-rc.3] - 2019-03-29

• [Fixed] Android NullPointerException with Bundle#getExtras (#674).
• [Fixed] Android not persisting providerchange location when location-services re-enabled.

[1.0.0-rc.2] - 2019-03-27

• [Fixed] An Android foreground-service is launched on first install and fails to stop.

[1.0.0-rc.1] - 2019-03-25

Breaking Changes

• [Changed] The license format has changed. New 1.0.0 licenses are now available for customers in the product dashboard.

Fixes

• [Fixed] iOS missing native destroyLog implementation (thanks to @joserocha3)
• [Fixed] Missing Dart implementation for requestPermission method (thanks to @joserocha3)
• [Fixed] Logic bugs in MotionActivity triggering between stationary / moving states.
• [Fixed] List.map Bug in Dart api addGeofences.

New Features

• [Added] Android implementation for useSignificantChangesOnly Config option. Will request Android locations without the persistent foreground service. You will receive location updates only a few times per hour: useSignificantChangesOnly: true:

useSignificantChangesOnly: false:

• [Added] Android now implements a "stationary geofence", just like iOS. It currently acts as a secondary triggering mechanism along with the current motion-activity API. You will hear the "zap" sound effect when it triggers. This also has the fortunate consequence of allowing mock-location apps (eg: Lockito) of being able to trigger tracking automatically.

• [Added] The SDK detects mock locations and skips trigging the stopTimeout system, improving location simulation workflow.

• [Added] Android-only Config option geofenceModeHighAccuracy for more control over geofence triggering responsiveness. Runs a foreground-service during geofences-only mode (#startGeofences). This will, of course, consume more power.

await BackgroundGeolocation.ready(Config
  geofenceModeHighAccuracy: true,
  desiredAccuracy: Config.DESIRED_ACCURACY_MEDIUM,
  locationUpdateInterval: 5000,
  distanceFilter: 50
));

BackgroundGeolocation.startGeofences();

• [Added] Android implementation of startBackgroundTask / stopBackgroundTask. This implementation uses a foreground-service. I've tried using Android's JobService but these tasks are queued by the OS and run only periodically.

  // an Android foreground-service has just launched (in addition to its persistent notification).
  int taskId = await BackgroundGeolocation.startBackgroundTask();

  // Do any work you like -- it's guaranteed to run, regardless of background/terminated.
  // Your task has exactly 30s to do work before the service auto-stops itself.

  // Execute an HTTP request to test an async operation.
  String url = "http://tracker.transistorsoft.com/devices?company_token=$_username";
  String result = await http.read(url).then((String result) {
    print("[http test] success: $result");
    // Terminate the foreground-service.
    BackgroundGeolocation.stopBackgroundTask(taskId);
  }).catchError((dynamic error) {
    print("[http test] failed: $error");
    // Always be sure to stop your tasks, just like iOS.
    BackgroundGeolocation.stopBackgroundTask(taskId);
  });

Logging for background-tasks looks like this (when you see an hourglass, a foreground-service is active)

 [BackgroundTaskManager onStartJob] ⏳ startBackgroundTask: 6
 .
 .
 .
 [BackgroundTaskManager$Task stop] ⏳ stopBackgroundTask: 6

• [Added] New custom Android debug sound FX. More documentation will be added to the docs but here's a basic description from the code:

    public static final String LOCATION_RECORDED        = OOOOIII;
    public static final String LOCATION_SAMPLE          = CLICK_TAP_DONE;
    public static final String LOCATION_ERROR           = DIGI_WARN;

    public static final String MOTIONCHANGE_FALSE       = MARIMBA_DROP;
    public static final String MOTIONCHANGE_TRUE        = CHIME_SHORT_CHORD_UP;
    public static final String STATIONARY_GEOFENCE_EXIT = ZAP_FAST;

    public static final String STOP_TIMER_ON            = CHIME_BELL_CONFIRM;
    public static final String STOP_TIMER_OFF           = BELL_DING_POP;

    public static final String HEARTBEAT                = PEEP_NOTE;

    public static final String GEOFENCE_ENTER           = BEEP_TRIP_UP_DRY;
    public static final String GEOFENCE_DWELL           = BEEP_TRIP_UP_ECHO;
    public static final String GEOFENCE_EXIT            = BEEP_TRIP_DRY;

    public static final String WARNING                  = DIGI_WARN;
    public static final String ERROR                    = MUSIC_TIMPANI_ERROR;

⚠️ These debug sound FX consume about 1.4MB in the plugin's tslocationmanager.aar. These assets can easily be stripped in your release builds by adding the following gradle task to your app/build.gradle (I'm working on an automated solution within the context of the plugin's build.gradle; so far, no luck). Big thanks to @mikehardy.

/**
 * Purge flutter_background_geolocation debug sounds from release build.

def purgeBackgroundGeolocationDebugResources(applicationVariants) {
    applicationVariants.all { variant ->
        if (variant.buildType.name == 'release') {
            variant.mergeResources.doLast {
                delete(fileTree(dir: variant.mergeResources.outputDir, includes: ['raw_tslocationmanager*']))

            }
        }
    }
}

android {
    //Remove debug sounds from background_geolocation plugin
    purgeBackgroundGeolocationDebugResources(applicationVariants)

Removed

• [Changed] Removed Android config option activityRecognitionInterval. The Android SDK now uses the more modern ActivityTransistionClient API which is a higher level wrapper for the traditional ActivityReconitionClient. AcitvityTransitionClient does not accept a polling interval, thus actiivtyRecognitionInterval is now unused. Also, ActivityTransitionClient emits similar on_foot, in_vehicle events but no longer provides a confidence, thus confidence is now reported always as 100. If you've been implementing your own custom triggering logic based upon confidence, it's now pointless. The ActivityTransitionClient will open doors for new features based upon transitions between activity states.
