starting two different FileDownloadQueueSets (with different tasks) at once results in
java.lang.IllegalStateException: This task is running -781468002, if you want to start the same task, please create a new one by FileDownloader.create
Is it two different FileDownloadQueueSets use the same FileDownloadListener object?
yes
OK, I know how it's going on, I will fix this bug, and it would be fixed in next version. Thank you for your issue.
Fixed since 0.3.4.
