Question

我的应用程序（使用HERE Android SDK）在进行模拟转弯导航时崩溃，异常日志如下，请告诉我们如何解决它。

设备型号：SM-G9008V
SDK：5.0 ----------- java.util.concurrent.RejectedExecutionException：任务android.os.AsyncTask$3@36d584c9被拒绝 java.util.concurrent.ThreadPoolExecutor@23d4f7ce [正在运行，池大小= 9，活动线程= 9，排队任务= 128，完成任务= 828] java.util.concurrent.ThreadPoolExecutor中的$ AbortPolicy.rejectedExecution（ThreadPoolExecutor.java:2011） java.util.concurrent.ThreadPoolExecutor.reject（ThreadPoolExecutor.java:793） java.util.concurrent.ThreadPoolExecutor.execute（ThreadPoolExecutor.java:1339） android.os.AsyncTask.executeOnExecutor（AsyncTask.java:590） com.nokia.maps.bf.c（LocationRestHandler.java:207） com.nokia.maps.bf.b（LocationRestHandler.java:198） com.nokia.maps.dn.b（PlacesReverseGeocodeRequest.java:256） com.nokia.maps.dn.a（PlacesReverseGeocodeRequest.java:28） com.nokia.maps.dn $ 1.run（PlacesReverseGeocodeRequest.java:104） android.os.Handler.handleCallback（Handler.java:739） android.os.Handler.dispatchMessage（Handler.java:95） android.os.Looper.loop（Looper.java:145） android.app.ActivityThread.main（ActivityThread.java:5835） java.lang.reflect.Method.invoke（Native方法） java.lang.reflect.Method.invoke（Method.java:372） com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run（ZygoteInit.java:1399） com.android.internal.os.ZygoteInit.main（ZygoteInit.java:1194）

Answer 1

您是否同时发出了多个请求？您似乎发出了太多请求并超出了未完成的最大数量：

java.util.concurrent.ThreadPoolExecutor@23d4f7ce [正在运行，池大小= 9，活动线程= 9，排队任务= 128，已完成任务= 828]

你在导航代码中做什么？你可以发一个片段吗？

Answer 2

为什么我会收到此错误消息？

如果您已超过ThreadPoolExecutor可排队的任务数，则会收到此错误消息。引发RejectedExecutionException的唯一时间是ThreadPoolExecutor。AbortPolicy是默认的RejectedExecutionHandler。

引用javadocs：

如果请求无法排队，则会创建一个新线程，除非这样会超过maximumPoolSize，在这种情况下，任务将是拒绝。

有最多的任务。在此处查看此问题/答案：Is there a limit of AsyncTasks to be executed at the same time?

@David，下面是代码片段：

if(navigationManager == null) {
            navigationManager = NavigationManager.getInstance();
            navigationManager.setMap(map);
        }

        // start listening to navigation events
        instructListener = new InstructListener();
        navigationManager.addNewInstructionEventListener(
                new WeakReference<NavigationManager.NewInstructionEventListener>(instructListener));

        // start listening to position events
        if (naviPositionListener == null) {
            naviPositionListener = new NaviPositionListener();
        }
        navigationManager.addPositionListener(
                new WeakReference<NavigationManager.PositionListener>(naviPositionListener));

        if (maneuverEventListener == null) {
            maneuverEventListener = new ManeuverEventListener();
        }
        navigationManager.addManeuverEventListener(
                new WeakReference<NavigationManager.ManeuverEventListener>(maneuverEventListener));


        if (myNavigationManagerEventListener == null) {
            myNavigationManagerEventListener = new MyNavigationManagerEventListener();
        }
        navigationManager.addNavigationManagerEventListener(new WeakReference<NavigationManager.NavigationManagerEventListener>(myNavigationManagerEventListener));

        if (rerouteListener == null) {
            rerouteListener = new MyRerouteListener();
        }
        navigationManager.addRerouteListener(new WeakReference<RerouteListener>(rerouteListener));

        if (safetySpotListener == null) {
            safetySpotListener = new MySafetySpotListener();
        }
        navigationManager.addSafetySpotListener(new WeakReference<NavigationManager.SafetySpotListener>(safetySpotListener));

        //add realistic view listener
        navigationManager.setRealisticViewMode(NavigationManager.RealisticViewMode.DAY);
        navigationManager.addRealisticViewAspectRatio(NavigationManager.AspectRatio.AR_4x3);

        if (realisticViewListener == null) {
            realisticViewListener = new MyRealisticViewListener();
        }
        navigationManager.addRealisticViewListener(
                new WeakReference<NavigationManager.RealisticViewListener>(realisticViewListener));


        //set map udpate mode
        navigationManager.setMapUpdateMode(NavigationManager.MapUpdateMode.ROADVIEW);
        navigationManager.setTrafficAvoidanceMode(NavigationManager.TrafficAvoidanceMode.DISABLE);

        //set natural guidance mode
        EnumSet<NavigationManager.NaturalGuidanceMode> modeset = navigationManager.getNaturalGuidanceMode();
        modeset.add(NavigationManager.NaturalGuidanceMode.TRAFFIC_LIGHT);
        modeset.add(NavigationManager.NaturalGuidanceMode.STOP_SIGN);
        modeset.add(NavigationManager.NaturalGuidanceMode.JUNCTION);

        navigationManager.setNaturalGuidanceMode(modeset);

        // add gps signal listener
        if (gpsSignalListener == null) {
            gpsSignalListener = new MyGpsSignalListener();
        }
        navigationManager.addGpsSignalListener(new WeakReference<NavigationManager.GpsSignalListener>(gpsSignalListener));


        if (speedWarningListener == null) {
            speedWarningListener = new MySpeedWarningListener();
        }
        navigationManager.addSpeedWarningListener(new WeakReference<NavigationManager.SpeedWarningListener>(speedWarningListener));

        //add lane info listener
        if (laneInfoListener == null) {
            laneInfoListener = new MyLaneInfoListener();
        }
        navigationManager.addLaneInfoListener(new WeakReference<NavigationManager.LaneInfoListener>(laneInfoListener));


        navigationManager.getRoadView().setOrientation(NavigationManager.RoadView.Orientation.DYNAMIC);
        navigationManager.getRoadView().addListener(new WeakReference<NavigationManager.RoadView.Listener>(roadViewListener));


        //start navigation
        long speed = 60; // meter per second
    navigationManager.simulate(mapRoute.getRoute(), speed);
