我创建了一个跟踪设备移动位置的服务.该服务由绑定到它的Activity启动,在此活动中有一个"开始跟踪"按钮.按下此按钮时,我需要服务在前台启动,以便它存储设备已移动到的位置,即使绑定到它的活动已关闭,或应用程序已最小化.

我知道,要使服务位于前台,必须显示通知.我试图这样做,但是当活动被销毁时,我无法获得显示通知或服务在前台工作.

由于通知渠道,Oreo的通知似乎已经发生变化,但我无法弄清楚需要采取哪些不同的措施.我正在测试它的设备是8.0.0.

这是mys服务:

public class LocationTrackerService extends Service {

    private LocationListener locationListener;
    private LocationManager locationManager;
    private IBinder binder = new LocalBinder();
    private boolean isTracking;
    private ArrayList<Location> trackedWaypoints;
    private String bestProvider;
    private Timer timer;
    private Distance distance;

    @SuppressLint("MissingPermission")
    @Override
    public void onCreate() {
        super.onCreate();

        locationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
        Criteria criteria = new Criteria();
        bestProvider = locationManager.getBestProvider(criteria, true);

        isTracking = false;

        locationListener = new LocationListener() {
            @Override
            public void onLocationChanged(Location location) {
                Intent intent = new Intent("location_update");
                intent.putExtra("latitude", location.getLatitude());
                intent.putExtra("longitude", location.getLongitude()); …
