当应用程序被刷掉时前台服务被杀死 [英] foreground service getting killed when app is swiped off

问题描述

我希望标题本身能说明我的问题是什么.

我有一个在前台运行的 Service.

@Overridepublic int onStartCommand(意图意图，int标志，int startId){NotificationCompat.Builder builder = new NotificationCompat.Builder(这);PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,新意图(这个，WidgetFlashReceiver.class).setAction(Constants.ACTION_NOTIFICATION_CLICK),PendingIntent.FLAG_CANCEL_CURRENT);builder.setContentIntent(pendingIntent);builder.setOngoing(true);builder.setAutoCancel(false);builder.setContentTitle("示例服务");通知通知 = builder.build();通知.icon = R.drawable.ic_launcher;Notification.flags |= Notification.FLAG_FOREGROUND_SERVICE;startForeground(NOTIFICATION_ID，通知)；返回 START_STICKY;}

但是当应用程序从最近的任务中被刷掉时，即使它是一个前台服务，这个服务也会被杀死.

感谢任何帮助.

解决方案

看这个 评论关于Android错误，我找到了这个解决方案，为我解决了问题！

AlarmManager almgr = (AlarmManager)MyContext.getSystemService(Context.ALARM_SERVICE);Intent timerIntent = new Intent(MyUniqueLabel);timerIntent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND);PendingIntent pendingOffLoadIntent = PendingIntent.getBroadcast(MyContext, 1, timerIntent, 0);

<块引用>

你必须做这些事情才能让它工作.

1.) 调用 addFlags 和意图并将其传递到 FLAG_RECEIVER_FORGROUND

2.) 在 PendingIntent.getBroadcast 中使用非零请求代码

如果您忽略其中任何一个步骤，它将无法工作.

I hope title itself says what's my question is.

I have a Service which runs in foreground.

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    NotificationCompat.Builder builder = new NotificationCompat.Builder(
            this);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,
            new Intent(this, WidgetFlashReceiver.class)
                    .setAction(Constants.ACTION_NOTIFICATION_CLICK),
            PendingIntent.FLAG_CANCEL_CURRENT);
    builder.setContentIntent(pendingIntent);
    builder.setOngoing(true);
    builder.setAutoCancel(false);
    builder.setContentTitle("Sample Service");
    Notification notification = builder.build();
    notification.icon = R.drawable.ic_launcher;
    notification.flags |= Notification.FLAG_FOREGROUND_SERVICE;
    startForeground(NOTIFICATION_ID, notification);
    return START_STICKY;
}

but this Service getting killed when app is swiped off from recent tasks even though it is a foreground Service.

Any help is appreciated.

解决方案

Looking at this comment about the Android bug, I found this solution that solve the problem for me!

AlarmManager almgr = (AlarmManager)MyContext.getSystemService(Context.ALARM_SERVICE);
Intent timerIntent = new Intent(MyUniqueLabel);
timerIntent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND);
PendingIntent pendingOffLoadIntent = PendingIntent.getBroadcast(MyContext, 1, timerIntent, 0);

you MUST do these things for it to work.

1.) Call addFlags and the intent and pass it in FLAG_RECEIVER_FORGROUND

2.) Use a non-zero request code in PendingIntent.getBroadcast

If you leave any of those steps out it will not work.
