If you really want to use Tor because you transmit “dangerous” content, you probably won’t use Youtube and don’t connect to many WiFi networks.
I agree with the former but not necessarily with the latter and think Tor should be used for non-“dangerous” content as well. And to broaden its user base, tor-hosted servers/apps have to be really simple to set up (ideally, even simpler than the non-privacy-conserving alternatives, e.g. dyndns).
So the consensus is to have a http-proxy option in the DavDroid settings, right?
I suggest to have the standard orbot values (localhost:8118) set as default.
So, how to proceed on this? If none else volunteers, I could try to write a patch that adds the UI. But it will probably take me a while…
PS: I updated the binary artefact of this patch once more, to have an intermediate solution…
