如何在Android中显示后台推送通知O //如何正确使用startForeground

public class MyService extends Service {
    private static final int NOTIFICATION_ID = 1;

    @Override
    public void onCreate() {
        super.onCreate();
        // 创建通知
        Notification notification = new NotificationCompat.Builder(this, "channel_id")
                .setContentTitle("后台推送通知")
                .setContentText("这是一个后台推送通知")
                .setSmallIcon(R.drawable.notification_icon)
                .build();

        // 将服务置于前台
        startForeground(NOTIFICATION_ID, notification);
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // 在这里处理后台任务逻辑

        // 更新通知的内容
        Notification notification = new NotificationCompat.Builder(this, "channel_id")
                .setContentTitle("后台推送通知")
                .setContentText("后台任务正在运行")
                .setSmallIcon(R.drawable.notification_icon)
                .build();

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(NOTIFICATION_ID, notification);

        return START_STICKY;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        // 停止前台服务
        stopForeground(true);
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}
