Full Changelog

Enhancements:

  • Added a guaranteed callback to MonitorNotifier#didDetermineStateForRegion(int state, Region region) when starting monitoring. At app startup, this returns the previously known persisted state. (#405, David G. Young)

2.8.1 / 2016-04-18

Full Changelog

Bug Fixes:

  • As of the 2.8 release, scanning would never start on Android 4.x devices unless the application manually added ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permissions to the AndroidManifest.xml. This fix makes it so this is not required for 4.x devices, as was the case prior to 2.8. (#365, David G. Young)

2.8 / 2016-03-28

Full Changelog

Enhancements:

  • Retains monitored regions across service restarts, preventing apps from getting multiple region entry callbacks each time the service restarts. (#315, Mateusz Sarzyński)
  • Add string identifier to BeaconParser which can be referenced by decoded Beacon object, allowing easy determination of beacon type. (#333, David G. Young)
  • Switch to using ELAPSED_REALTIME clocks, so scanning doesn't stop on devices without a battery-backed RTC (#339, Luca Niccoli)
  • Add ability to access raw EDDYSTONE_TLM data for sending info to Google services. (#328, David G. Young)
  • New distance formula for Moto X Pro (#330, David G. Young)
  • Adjust the BackgroundPowerSaver so it accepts any context (#355, Kristof Snyers)
  • Add support for pre-Eddystone UriBeacon layout (#358, David G. Young)

Bug Fixes:

  • Multiple consumers of the BeaconService will now each get a onBeaconServiceConnected() callback. (#340, Mateusz Sarzyński)
  • Don't scan for bluetooth devices if permission has not been granted in Android 6. This prevents large number of exceptions in the log. (#327, Alex Urzhumtcev)
  • Fix crash on beacon parsing comparison overrun (#324, David G. Young)

2.7.1 / 2015-11-17

Full Changelog

Bug Fixes:

  • Stopping and starting monitoring disables scans (#317, David G. Young)

2.7 / 2015-11-12

Full Changelog

Enhancements:

  • Adds hardware accelerated detection of Eddystone frames in the background on Android 5+ (#314, David G. Young)
  • Provides ability to forward BLE scan callbacks for non-beacon advertisements (#267, Paul Peavyhouse)

Bug Fixes:

  • Fix rescheduling of alarms in the distant future so they don't inadvertently go off right away (#312, Mateusz Sarzyński)
  • Only request ACCESS_COARSE_LOCATION permission on Android M (#296, Henning Dodenhof)

2.6.1 / 2015-09-30

Full Changelog

Bug Fixes:

  • Allow Regions to match beacons with fewer identifiers if the extra region identifiers are null. This allows matching Eddystone-UID and Eddystone-URL beacon with the default Region with three null identifiers. This started failing in version 2.6. (#295, David G. Young)
  • Declare the ACCESS_COARSE_LOCATION permission in the manifest since it is required for Android 6.0. This is helpful to keep beacon detection working on Android 6.0 for apps that don't explicitly declare this in their own manifest. (#295, David G. Young)

2.6 / 2015-09-29

Full Changelog

Enhancements:

  • Make region exit period configuration with a default of ten seconds (#283, Alex Urzhumtcev)
  • When scanning in Background on Android 5+, do a full scan without filters during the main scan period (default for 10 seconds once every 5 minutes) in case scan filters are unavailable (#293, David G. Young)
  • Common open-source BeaconParser layouts are defined as constants on BeaconParser (Commit 0101970010, David G. Young)
  • Bluetooth address is now a field on Region, offering the option of monitoring and ranging for all beacon transmissions from a known device's MAC Address (#254, David G. Young)
  • Target SDK bumped to 23 for Android 6.0 (#293, David G. Young)

Bug Fixes:

  • Fix potential ConcurrentModificationException with distance calculation (#245, Dawid Drozd)
  • Fix potential NullPointerException in Beacon#hashCode (#249, Sam Yang)
  • Switch BeaconParsers list to be a CopyOnWriteArrayList to avoid UnsupportedOperationException changing list after starting scanning. (#290, Matthew Michihara)
  • Fix crash when region has more identifiers than beacon (#252, David G. Young)
  • Fix bugs with compressing Eddystone-URL to bytes and back (#263, Michael Harper)
