Please, explain the difference:
When trying 7z.exe a be_social_plugin.apk 1111.txt commandline request, the result is:
7-Zip 9.20 Copyright (c) 1999-2010 Igor Pavlov 2010-11-18
Error: be_social_plugin.apk is not supported archive
But when you rename apk to zip: be_social_plugin.apk -> be_social_plugin.zip, 7z works great:
Updating archive be_social_plugin.zip
Everything is Ok
apk files are only renamed zip files, so there are no differences between zip and apk. Seems to be a bug, isn't it?
7z a be_social_plugin.apk -tzip 1111.txt
apk file format is not "just renamed zip file"; but zip based upon jar.
it is no bug.
7z a be_social_plugin.apk -tzip 1111.txt has worked correctly. Thanks for your help!
