Android 5 only: Crash on exit of app while BT off

[mattwritescode]

For Android 5 devices, while Bluetooth is turned off, app crashes immediately after pressing the home button. This is replicable in the https://github.com/AltBeacon/android-beacon-library-reference.

Fixed in release 2.1.1

I think there is one instance of this issue still to fix, Line number 173 which causes crash sometimes, find the trace below

Nice catch! That was a copy/paste error.

Wait, so we need to make another release of android beacon library now? I'm going to wait a week after it comes out before putting it into all the other libraries this time.

I am still experiencing the same issues in the AltBeacon 2.9

It seems like this issue only happens on HTC devices, as Crashlytics is not reporting crashes on any other devices except HTC.

[davidgyoung]

Thanks for this report. Catching this exception seems like a reasonable fix.

Please see #414 for further discussion on a related issue with HTC devices. This issue had a different root cause and is closed.
