Please someone find a proper fix for this issue.

I'm limiting the block count to 1 to bypass this issue for now. But there is no reason to use this library if I cannot download in multiple blocks...

[blueberry404]

I am facing this issue in android 10+ devices. @ymqq solution worked for me. I was not able to use close() method as he specified, therefore I had to add "okdownload" as submodule and modify MultiPointOutputStream class' close() method.

synchronized void close(int blockIndex) throws IOException {
        final DownloadOutputStream outputStream = outputStreamMap.get(blockIndex);
        if (outputStream != null) {
            outputStream.close();
            synchronized (noSyncLengthMap) {
                // make sure the length of noSyncLengthMap is equal to outputStreamMap
                outputStreamMap.remove(blockIndex);
                noSyncLengthMap.remove(blockIndex);
            }
            Util.d(TAG, "OutputStream close task[" + task.getId() + "] block[" + blockIndex + "]");
        }
    }

[bloworlf]

I had to add "okdownload" as submodule and modify MultiPointOutputStream class' close() method.

How did you added okdownload as a submodule? I have plenty of errors when I try to.

[blueberry404]

@bloworlf As far as I remember, I also faced errors and they were probably due to import paths. I had to spend sometime fixing those errors, and then it was good to go.

[bloworlf]

@bloworlf As far as I remember, I also faced errors and they were probably due to import paths. I had to spend sometime fixing those errors, and then it was good to go.

Yeah, I forgot to comment here that I got it fixed. Anyone using this should be aware of that. Spent 1 or 2 hrs just to import the "okdownload" module: checking gradle files, changing lines of import code...)

Now my main issue is with notifications. When there's a lot of files downloading at once, it doeant correctly update the notifications. The files are downloaded, but some of the notification stay in "ongoing" state.

[liuyewang]

Me too, but I can't change it
