Version 0.3 of the SDK:
- Background monitoring is more robust and using AlarmService to invoke scanning.
- Default values for background monitoring were changed. Scanning is performed for 5 seconds and then service sleeps for 25 seconds. Those values can be changed with BeaconManager#setBackgroundScanPeriod.
- Beacons reported in RangingListener#onBeaconsDiscovered are sorted by accuracy (estimated distance between device and beacon).
- Bug fixes.
