Release Notes - Backspin Android SDK

every device language (even with non-arabic numbers) will now use US locale for date format parsing

solved compatibility issues with out-dated server versions

data store was not correctly cleaned up on the database upgrade

fixed a bug with the background initialization of the Sdk

several apps which integrate the Sdk will generate different device ids for the app registration

several asset tracking bug fixes

beacon battery scanner will now re-schedule the upload procedure

asset tracking user token can be changed in case of no active root venue

notification module initializes in the background now

Fixed a bug in the background position calculation

Tls12SocketFactory will not be obfuscated on app minification anymore

encapsulated Tls12SocketFactory.createTls120SSLContext() to use it in your own http client

bug fix for sdk clean up

bug fix in obfuscation

increased kotlin to version 1.2.30 and fixed some annotationProcessor dependencies

use setBeaconBatteryScanEnabled to enable an automatic upload of the scanned beacon battery levels (only if your installation has this feature)

bug fix for AnalyticsDispatcher which crashed some times when the app returns from the background

fixed a positioning bug in the new averaging logic

fixed bugs in some of the local data sources

completely re-worked the current data loading module

ranged beacons from all levels are now used for position calculation (UseBeaconsFromAllLevels)

rssi filter can also filter out beacons which are to far away which is not enabled by default and only recommended for specific installations (SensibleBeaconFilterDistance)

if a level change is detected the position will directly be published instead of waiting for the next publish interval

SensibleDistanceFilter threshold increased to 2.5m/s and activated by default now

the beacon scan callbacks always return a collection of scan results which is sorted by their estimated rssi values descending

increased kotlin to version 1.2.20

increased google support library to version 27.0.2

increased google play services to version 11.8.0

increased buildToolsVersion to 27.0.3

increased compileSdkVersion and targetSdkVersion to 27

the analytics event sending interval can now be adjusted with the help of the analytics configuration

increased OkHttp library to version 3.9.0

fixed a bug concerning not synchronized asset tracking methods

adaptive position calculation is enabled by default

deactivated kalman filter of position module by default

position path snapping is disabled by default

increased altbeacon library to version 2.12.3

increased java websocket library to version 1.3.6

fixed a bug concerning the properties to exclude of the Coupon and CouponCategory classes

increased buildToolsVersion, compileSdkVersion, targetSdkVersion to 26

added new google maven repository and updated google support libraries to 26.1.0

ok http network logging uses the SDK’s Logger class now

AssetWatcher will only be notified when there is an according asset in the local database

check if ScanModule is running before toggling the auto background mode

added support for bluloc crypto v2 beacons

ScanConfig.setUsingCryptoBeacons is deprecated now as everything will be setup in the commander web frontend

You can now mix crypto v1, v2 and none encryption in one installation

completely re-worked the Turn-By-Turn directions

corrected getTrigger in ZoneAlarm model and added getAssetId method

fixed issues when inserting assets and zone alarms

removed some obsolete log output

RootVenuesLoadedListener has worker thread annotations now

added BackspinSdk.Assets.loadZones method to public api

eager loading depth of entities was 1 by default therefore all sub-entities lazy loaded their data unintentionally

load methods of asset tracking api did not save the results to the local database

fixed a bug that on occasion caused a running navigation to suddenly stop

new beacon library update integrated

Sdk initialization can also be done on background threads (non-ui threads) now

AssetWatcher only notifies about events for the current root venue

WebSocket will not be started when user token is empty

several improvements on navigation graph generation

walking detector also works on devices without linear acceleration sensor

the positioning module calculates a movement direction now

fixed a bug in the asset tracking zone alarms

added new WalkingSensorAccelerationPeak which is now the default movement detector used by the adaptive position calculation

several improvements on the adaptive position calculation

new default position configuration for SensibleRssiThresholdFactor: 1.15 → 1.1

adaptive position calculation is now less reactive and more stable

AssetWatcher has a removeAsset method now

added web socket communication to asset tracking

BackspinSdk.Assets.setUserToken is deprecated now, use the ConnectionConfig.setUserToken instead

asset positions which have no corresponding asset yet will be simply ignored

getter for external id in Asset was missing

fixed null reference exception when calling AssetPosition.getIndoorLocation

OnNotificationListener is deprecated now, use NotificationListener instead, because it also passes information about the source of the notification (beacon or zone)

added getLevel to Zone object

added IntegerUtil.random method

NavigationTask related calculations won’t block the UI thread anymore

fixed a navigation crash based on concurrency problems

added BackspinSdk.Asset.loadAssetsByExternalId and BackspinSdk.Asset.getAssetByExternalId methods

fixed a bug that impacted offline capabilities

it is now possible to create and enqueue analytics events without an active root venue

added BackspinSdk.initRootVenue method to quickly initialize a previously loaded root venue

You can now start advertisements via the BackspinSdk.Scan.startAdvertisement method

Added AssetWatcher

NavigationTask.onRouteCalculated is no longer called when the route has not changed

NavigationTask now performs a route snapping of the received position and returns it via the new OnPositionSnappedListener

NavigationTask does not perform a complete route calculation on every calculate call - It now tries to reuse the already calculated route as long as possible

added two new settings to the NavigationConfig: DistanceDifferenceForRouteUpdateMeters, DistanceDifferenceForNewRouteCalculationMeters last

BackspinSdk initialization checks if the application context was closed during network request.

added CollectionUtil.first and .last methods

added asset tracking module
