stopForeground(true) 在服务上调用，给我一个类名空问题

Question

这是我开始服务的方式：

    public void startService(){
        if (!isRunningInForeground()) {
            Log.i("#foregroundservice", "Starting service");
            bindIntent = new Intent(PSLocationService.this, PSLocationService.class);
            startService(bindIntent);
        }
    }

我在 onStartCommand 上执行此操作：

   @Override
public int onStartCommand(Intent intent, int flags, int startId) {
    PSLocationService.startId = startId;
    if (PSApplicationClass.getInstance().isAutoPilotAllowed() || PSTrip.getActiveTrip() != null) {
        Log.i("#foregroundservice", "onStartCommand");
        Intent notificationIntent = new Intent(this, PSTimelineFragmentsActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
        Notification notification = new Notification.Builder(this)
                .setPriority(Notification.PRIORITY_MAX)
                .setContentTitle(getText(R.string.passenger_name))
                .setContentText(getText(R.string.getStarted_switch_on_toplabel))
                .setSmallIcon(R.drawable.notification_icon)
                .setContentIntent(pendingIntent)
                .build();
        startForeground(1338, notification);
    }
    return super.onStartCommand(intent, flags, startId);
}

当我与 googleApiClient 断开连接时，我想这样停止它：

  if (isRunningInForeground()) {
        Log.i("#foregroundservice", "Stopping service: " + bindIntent);
        stopForeground(true);
        stopSelf();
    }

它总是在 stopForeground(true) 方法处崩溃并出现此错误：

11-10 12:59:50.026: E/AndroidRuntime(10731): java.lang.NullPointerException: class name is null
11-10 12:59:50.026: E/AndroidRuntime(10731):    at android.content.ComponentName.<init>(ComponentName.java:114)

确实通过从 activity class 而不是我的 ApplicationClass 调用 stopForeground(true) 来使其工作。另外，我没有使用 stopForeground，而是这样做：

Intent serviceIntent = new Intent(context, PSLocationService.class);
context.stopService(serviceIntent);

stopForeground(true) 在服务上调用，给我一个类名空问题

stopForeground(true) called on a Service, gets me a classname null issue

android

android-intent

service

classname

foreground-service
