Some issues with POSIX wrapper

[proninyaroslav]

Hi. I know that your projects were split, but I think that these are common problems for everyone:

• [Android][POSIX wrapper] Native crash if open() function returns -1
• libtorrent doesn't call remove() in POSIX wrapper
• [TorrentBuilder] Incorrect work with Storage Access Framework
• [TorrentBuilder] crash when creating a large torrent with POSIX wrapper
• [Android] An app with POSIX wrapper crashes if launched in debug mode
• [Android][POSIX wrapper] Periodic Try again (code 11) error during downloading

Please see master branch of the app for example of usage: https://github.com/proninyaroslav/libretorrent/tree/master. If necessary, I can create a separate branch with frostwire-jlibtorrent instead of libtorrent4j

The main code that can help you navigate:

• core/system/LibTorrentSafAdapter.java - a POSIX wrapper class.
• core/system/SafFileSystem.java - used to work with SAF, for example in POSIX wrapper.
• core/TorrentBuilder.java - a wrapper for org.libtorrent4.TorrentBuilder class.
• ui/createtorrent/CreateTorrentViewModel.java - a view model logic that uses TorrentBuilder wrapper.
• core/model/session - implementation of org.libtorrent4.SessionManager.

@gubatron Why did you close the issue? These issues are relevant to this day, although they were opened in another repository.

[gubatron]

a lot has changed with android 11 and 12

@gubatron Much has been fixed, or is there a much that cannot be fixed?

You are using posix_wrapper in the frostwire app, but it makes little sense if it doesn't work as expected. You have to do something about it.

not sure what you mean by "doesn't work as expected", downloads writes and reads just fine on all android versions.
