Question

我有一个服务，使用ion库下载一些文件，下载完成后我想将下载的文件保存到数据库realm database 问题是当用户从多任务中清除应用程序时，应用程序崩溃并在logcat中显示ArrayIndexOutOfBoundsException 我认为问题是当应用程序被清除时模型类被破坏

这是代码

//服务代码

List<Surah> surahList;

 @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        if (intent != null)
            reciterName = intent.getStringExtra("reciterName");

        surahList = realm.where(Surah.class).equalTo("reciterName", reciterName).findAll();
        Surah surah = surahList.get(10);
        String folderName = surah.getReciterName() + " " + surah.getRewaya();
        File path = new File(Environment.getExternalStorageDirectory() + "/Quran Sound/" + folderName + "/" + surah.getSurahNumberMp3());


        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
        builder
                .setSmallIcon(R.drawable.ic_stat_noti);
         final NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        notificationManager.notify(2, builder.build());
        Ion.with(this)
                .load(surah.getSurahLink())
                .write(path)
                .setCallback(new FutureCallback<File>() {
                    @Override
                    public void onCompleted(Exception e, File result) {
                        Toast.makeText(DownloadService.this, result + "", Toast.LENGTH_SHORT).show();
                        Log.d("3llomi", "ion Download Finished!");
                        notificationManager.cancel(2);
                        stopSelf();
                    }
                });

        return START_STICKY;
    }

Answer 1

好的问题是reciterName来自Activity到Service的{{1}}使用意图在从多任务中清除应用时被销毁所以我改变了 return START_STICKY至return START_REDELIVER_INTENT

使用服务从多任务清除应用程序后，域结果为空
