I'm recently trying to build an application that uses AltBeacon Library.

The problem that I'm facing right now is this: I created an Application class in this way:

 beaconManager = beaconManager.getInstanceForApplication(this);

 beaconManager.getBeaconParsers().clear();
 beaconManager.getBeaconParsers().add(new BeaconParser().
 setBeaconLayout("m:0-3=4c000215,i:4-19,i:20-21,i:22-23,p:24-24"));


 beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));


 beaconManager.setRegionStatePersistenceEnabled(false);

 Notification.Builder builder = new Notification.Builder(this);
 builder.setSmallIcon(R.drawable.icon);



 builder.setBadgeIconType(Notification.BADGE_ICON_NONE);


 Intent buttonIntent = new Intent(getApplicationContext(), ButtonReceiver.class);
 buttonIntent.putExtra("notificationId",NOTIFICATION_ID);

 PendingIntent btPendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, buttonIntent,0);


 builder.addAction(R.drawable.stop,"Termina Rilevamento.", btPendingIntent);



 builder.setColor(getResources().getColor(R.color.mygreen));

 builder.setContentIntent(btPendingIntent);

 builder.setPriority(Notification.PRIORITY_MAX);


 builder.setContentTitle("Rilevazione autenticazione in corso.");
 Intent intent = new Intent(this, LoginActivity.class);
 PendingIntent pendingIntent = PendingIntent.getActivity(
 this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT
 );
 builder.setContentIntent(pendingIntent);



 NotificationChannel channel = new NotificationChannel("My Notification Channel ID",
 "My Notification Name", NotificationManager.IMPORTANCE_DEFAULT);
 channel.setDescription("My Notification Channel Description");
 NotificationManager notificationManager = (NotificationManager) getSystemService(
 Context.NOTIFICATION_SERVICE);
 notificationManager.createNotificationChannel(channel);
 builder.setChannelId(channel.getId());



 beaconManager.enableForegroundServiceScanning(builder.build(), 456);


 beaconManager.setEnableScheduledScanJobs(false);
 beaconManager.setBackgroundBetweenScanPeriod(0);
 beaconManager.setBackgroundScanPeriod(1100);

 Region region = new Region("Region iniziale",null,Identifier.parse("789"),null);
 regionBootstrap = new RegionBootstrap(this, region);

 backgroundPowerSaver = new BackgroundPowerSaver(this);

Where the Button on the notification points to a BroadCastReceiver class that is ButtonReceiver.
In button receiver I want to execute the action of disabling the foreground service and to close out the application.
I do it in this way:

 int notificationId = intent.getIntExtra("notificationId", 0);

 NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
 manager.cancel(notificationId);

 AndroidWalkEnrollmentApplication prova = new AndroidWalkEnrollmentApplication();
 prova.disableMonitoring();

inside the onReceive() method.

So the problem is this: in disableMonitoring() I follow the example of the Android-Beacon-Reference and so to disable the foreground scanning I do:
bootstrap.disable() and bootstrap=null. The problem is that it seems to not work. When I press the button inside the notification the foreground mode it's note disabled. I also tried to execute Beaconmanager.disableForegroundService() but it doesn't actually disable it.

Any clue?

There is a bug in the 2.15.2 release of the library that prevents stopping the foreground service properly. But good news: this has been very recently fixed in this experimental release:

https://github.com/AltBeacon/android-beacon-library/releases/tag/more-reliable-service-stop2

You may use the above fix immediatly by following the integration instructions on the release. This change will also be included in a formal release in 1-2 weeks.
