To try this yourself, it'll be easiest using the Guardian Project fork, which is in sync on GitHub and GitLab:

I looked into it a bit, but couldn't quite figure out what was being tested there. Is it Tor's "smartlist" functions? stdin/stdout/stderr have annoying, arbitrary restrictions in Android, so it could be related to that. For example, "native" code loaded from a shared library will have stdin/stdout/stderr redirected to /dev/null, while in Java code, it is reachable. There is a related example on legacy/trac#32036 (moved)

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
