> Key: COMPRESS-601
> URL: https://issues.apache.org/jira/browse/COMPRESS-601
> Project: Commons Compress
> Issue Type: Improvement
> Components: Compressors
> Affects Versions: 1.21
> Reporter: Vladimir Ignjatijevic
> Priority: Minor
>
> Having some troubles unpacking a 7zip archive on Android using:
> * org.apache.commons:commons-compress:1.21
> * org.tukaani:xz:1.9
> First I've tried with this archive:
> [https://kohina.duckdns.org/HVSC/HVSC_75-all-of-them.7z]
> I'm getting following exception:
> java.io.IOException: Unsupported compression method [3, 4, 1]
> From the creators of this archive I've found out that all files in this
> archive are compressed with BCJ2 LZMA except for some of them which are PPMd.
> I was suggested to try this one which has only BCJ2 LZMA:
> [https://kohina.duckdns.org/HVSC/HVSC_74-all-of-them.7z]
> There I get the following exception:
> java.io.IOException: Multi input/output stream coders are not yet supported
>
> Am I doing something wrong or these methods are still not supported by
> SevenZip?
