getBeaconParsers().add throws java.lang.UnsupportedOperationException

Question

I get java.lang.UnsupportedOperationException and the app crashes on following line:

this.beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));

This is part of the stack trace:

java.lang.UnsupportedOperationException
            at java.util.Collections$UnmodifiableCollection.add(Collections.java:928)
            at com.cc.office.BeaconMonitoring.BeaconMonitoringCoordinator.detectBeaconsUsingMonitorNotifier(BeaconMonitoringCoordinator.java:75)

The line

this.beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));

was being called after

beaconManager.bind(this);

The issue was fixed by calling the add function before bind.
