Issue

1. What problem do you get?
2. Which version of FileDownloader are you using when you produce such problem?
3. How to reproduce such problem?
4. Do you set FileDownloadLog.NEED_LOG=true?
5. Could you please reproduce this problem and provide all main process and :filedownloader process logcat
6. Can you fix it by yourself and request PR, if not, what's problem do you get when you try to fix it

P.S. If you don't know how to get :filedownloader process, it's recommended to using pidcat to just filter all your application logcat, or define process.non-separate=true on filedownloader.properties

请在Issue前认真的跟进上面提到的建议，这样将可以极大的加快你遇到问题的处理。

Start by collecting the FileDownloader version, reproduction steps, and Logcat output from both the main and :filedownloader processes, as requested in the issue template. No source file or test is identified; the issue is complete only when the unexpected end-of-stream failure is reproducible and its cause and resolution are established.
