Prevent to call The didExitRegion() method of MonitorNotifier callback automatically

Question

When the application goes to the background, didExitRegion() of MonitorNotifier callback is called automatically.

How can I prevent that automatic call?

@Override
    public void **onBeaconServiceConnect**() {
        System.out.println("call onBeaconServiceConnect()");
        try {
            System.out.println("call notifier ");


            mBeaconManager.setRangeNotifier(this);
            mBeaconManager.startMonitoringBeaconsInRegion(mAllBeaconsRegion);


            mBeaconManager.setMonitorNotifier(new MonitorNotifier() {
                @Override
                public void didEnterRegion(Region region) {
                    System.out.println("monitor enter " + region.getId1());
                }


                @Override
                public void didExitRegion(Region region) {
                    System.out.println("monitor exit " + region.getId1());
                }


                @Override
                public void didDetermineStateForRegion(int i, Region region) {
                    System.out.println("monitor " + region.getId1());
                }
            });

            mBeaconManager.startRangingBeaconsInRegion(mAllBeaconsRegion);

        } catch (RemoteException e) {
            e.printStackTrace();
            System.out.println("call notifier exception"+e.toString());
        }
    }
