2.0.0

Added

• LaserScanner was expanded to give access to the cache of discovered providers and the option to re-discover them:
  • discoverProviders()
  • getProviderCache()
• ScannerServiceApi methods to expand control on the scanner search, lifecycle and client hooks:
  • unregisterClient()
  • restartProviderDiscovery()
  • getAvailableProviders()
  • updateScannerSearchOptions()
• ScannerSearchOptions methods to simplify manipulating intent extras from the service API:
  • fromIntentExtras()
  • toIntentExtras()
• ScannerSearchOptions options to decide whether the service should start searching for scanners on bind or not
• Most (if not all) callback interfaces now have a Proxy implementation that centralize jumps to the UI thread:
  • ProviderDiscoveredCallback
  • ScannerCommandCallback
  • ScannerConnectionHandler
  • ScannerDataCallback
  • ScannerInitCallback
  • ScannerStatusCallback
• New and updated scanner SDKs:
  • Zebra: rework of the existing OSS driver for Zebra, fixing mistakes in the protocol and adding bases for future BLE support (not yet tested)
  • Athesi E5L (model RD50TE): add OSS driver, different from the SPA43LTE model
  • Honeywell EDA52: add OSS driver, device also compatible with the old non-OSS driver
• The demo application (demoscannerapp/) was expanded to include a Settings activity, allowing to tune scanner search options and showcasing the different filters available.
• Javadoc where it was missing
• Many tests !

Changed

• Project structure was updated to be easier to navigate, most notably the api and bt (bluetooth) packages
• README was updated with a more accurate compatibility matrix and links to mentionned classes
• ScannerForeground and ScannerBackground were merged into the Scanner interface which now regroups all scanner implementations
• ForegroundScannerClient and BackgroundScannerClient were merged into ScannerClient interface, this is the interface the ScannerService user will need to implement to hook itself to service callbacks
• Scanner methods are now regrouped by feature category into subinterfaces instead of being directly available with potentially no effect, and a method is available for each feature to cast the scanner into the appropriate interface if the feature is available, or null if it is not available:
  • Scanner.WithBeepSupport and getBeepSupport() for beep-related commands
  • Scanner.WithTriggerSupport and getTriggerSupport() for software-controlled triggers
  • Scanner.WithIlluminationSupport and getIlluminationSupport() for flashlight-style illumination
  • Scanner.WithLedSupport and getLedSupport() for LED control
  • Scanner.WithInventorySupport and getInventorySupport() for inventory-related information
• StatusChangedCallback was reworked with localized messages and a set list of available statuses, making it easier to handle status changes.

Removed

• Library implementation of HID keyboards, the default android support is deemed sufficient
• ScannerServiceAPI methods that were not related to the scanner's lifecycle:
  • anyScannerSupportsIllumination()
  • anyScannerHasIllumination()
  • toggleIllumination()
  • beep()
  • ledColorOn()
  • ledColorOff()
  • getFirstScannerStatus()
• Many bugs !
