altbeacon如何使后台服务保持活动状态？

<service android:name=".MyBackgroundService" android:enabled="true" android:exported="true" />

public class MyBackgroundService extends Service {
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // 执行后台任务
        return START_STICKY;
    }
    
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}

Intent serviceIntent = new Intent(context, MyBackgroundService.class);
context.startService(serviceIntent);

public class MyBackgroundService extends Service implements BeaconConsumer {
    private BeaconManager beaconManager;
    
    @Override
    public void onCreate() {
        super.onCreate();
        beaconManager = BeaconManager.getInstanceForApplication(this);
        beaconManager.bind(this);
    }
    
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // 执行后台任务
        return START_STICKY;
    }
    
    @Override
    public void onBeaconServiceConnect() {
        beaconManager.addRangeNotifier(new RangeNotifier() {
            @Override
            public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
                // 处理扫描到的信标数据
            }
        });
        
        try {
            beaconManager.startRangingBeaconsInRegion(new Region("uniqueId", null, null, null));
        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }
    
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}
