Does anyone have any news on the effort for a new APK format that includes license texts and copyright information? This is sorely needed to produce any re-distributable software, legally compliant with the open source licenses of the components. A comment here last year (https://news.ycombinator.com/item?id=27113914 https://news.ycombinator.com/item?id=27113914) mentioned that the information would be available "in apk3", but I don't follow development to know whether this has been implemented already.
