OkDownload Version

v1.0.7

Problem Describe

1- Download a file 2- Delete downloaded file 3- Try to download same url & filename and you get NPE

My implementation:

OkDownload.setSingletonInstance(new OkDownload.Builder(getAppContext()).downloadStrategy(new DownloadStrategy() {
            @Override
            public int determineBlockCount(@NonNull DownloadTask task, long totalLength) {
                try {
                    int count = Math.max(3, Math.round((int)(totalLength / 5242880)));
                    if (count > 6) {
                        count = 6;
                    }
                    return count;
                } catch (Exception e) {
                    e.printStackTrace();
                }
                return 1;
            }
        }).build());

@sametbars Did you find a solution for this problem? what was causing the NPE?

I wrapped the whole compareIgnoreId function in try-catch block and returned false in catch block.
