未绑定被毁服务，同时活动被杀害 [英] Unbound services destroyed while activity is killed

问题描述

我要创建应用程序时被杀害，所以我创建了一个非绑定服务，以便它不会绑定到生命周期的活动，甚至是运行的服务。但每次我杀了长preSS和刷卡应用，服务也被打死。一些可以帮助我。
谢谢

服务

 公共类的MyService扩展服务{    公共GCMNotificationIntentService（）{
    }    @覆盖
    公众的IBinder onBind（意向意图）{
        Log.d（TAG，服务绑定）;
        返回null;
    }    @覆盖
    公共布尔onUnbind（意向意图）{
        Log.d（TAG，服务绑定）;
        返回super.onUnbind（意向）;
    }    @覆盖
    公共无效的onCreate（）{
        Log.d（TAG，服务创造）;
        super.onCreate（）;
    }    @覆盖
    公共无效的onDestroy（）{
        Log.d（TAG，服务destoryed）;
        super.onDestroy（）;
    }    @覆盖
    公众诠释onStartCommand（意向意图，诠释标志诠释startId）{        Log.d（TAG，服务启动）;        螺纹readerThread =新主题（新的Runnable（）{
            @覆盖
            公共无效的run（）{                而（真）{
                    Log.d（TAG，线程present）;
                    尝试{
                        //线程睡眠1000毫秒
                        视频下载（3000）;
                    }赶上（例外五）{
                        的System.out.println（E）;
                    }
                }
            }
        }）;
        readerThread.start（）;        返回super.onStartCommand（意向，旗帜，startId）;
    }}
 

和我从这样的活动称之为

startService（新意图（MyService.class.getName（）））;

该服务运行正常，直到应用程序在背景或前景，但是当我长
preSS和扫应用，服务也将停止，像这样的崩溃信息

        nManager.notify（NOTIFICATION_ID，builder.build（））;
        startForeground（NOTIFICATION_ID，builder.build（））;
    }
 

I want to create a service that is running even when app is killed so I created a unbound service so that it is not bind to activity lifecycle. But everytime I kill the app by long press and swipe, the service also get killed. Can some please help me. Thanks

Service

public class MyService extends Service {

    public GCMNotificationIntentService() {
    }

    @Override
    public IBinder onBind(Intent intent) {
        Log.d(TAG, "Service binded");
        return null;
    }

    @Override
    public boolean onUnbind(Intent intent) {
        Log.d(TAG, "Service unbound");
        return super.onUnbind(intent);
    }

    @Override
    public void onCreate() {
        Log.d(TAG, "Service created");
        super.onCreate();
    }

    @Override
    public void onDestroy() {
        Log.d(TAG, "Service destoryed");
        super.onDestroy();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        Log.d(TAG, "Service started");

        Thread readerThread = new Thread(new Runnable() {
            @Override
            public void run() {

                while(true) {
                    Log.d(TAG, "Thread present");
                    try {
                        // thread to sleep for 1000 milliseconds
                        Thread.sleep(3000);
                    } catch (Exception e) {
                        System.out.println(e);
                    }
                }
            }
        });
        readerThread.start();

        return super.onStartCommand(intent, flags, startId);
    }

} 

and I am calling it from activity like this

startService(new Intent(MyService.class.getName()));

The service runs fine until app is in background or foreground but when I long press and sweep the app, service also stops with crash message like this

解决方案

// Display sticky notification using below function in notification-bar.   
private static final int NOTIFICATION_ID=1;

 private void displayNotification() {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(
                this).setSmallIcon(R.drawable.ic_launcher).setContentTitle(
                "Player");
        builder.setContentText("content text");

        if (getFileStructure() != null) {
            String title = Utils.filter(getFileStructure().getTitle());
            if (title.length() > 45)
                title = title.substring(0, 44);
            builder.setContentText(Utils.filter(title));
        }
        Intent resultIntent = new Intent(PlayerService.this, MainActivity.class);
        PendingIntent resultPendingIntent = PendingIntent.getActivity(
                PlayerService.this, 0, resultIntent,
                PendingIntent.FLAG_UPDATE_CURRENT);
        builder.setContentIntent(resultPendingIntent);
        builder.setAutoCancel(false);
        NotificationManager nManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        nManager.notify(NOTIFICATION_ID, builder.build());
        startForeground(NOTIFICATION_ID, builder.build());
    }
