In Tor Browser for Windows, I can edit the torrc file for things like ExcludeNodes and ExitNodes. In Orbot for Android, there is a settings menu where these can be configured.
In Tor Browser 8.5.6 for Android, how do I configure these settings? Is there a torrc file somewhere in the Android file system? If so, where would I find it? If not, how do I configure ExcludeNodes and ExitNodes?
