It isn?t really meant for that, and would be overkill.

Running a local proxy server in an Android Service isn?t that difficult.

Alternatively, you could use the VPNBuilder interface, which would make "gate keeping and toll taking functions? work quite well.

I would look at NetGuard for that: https://github.com/M66B/NetGuard

This message tells you everything about Orbot without having to ask. It
provides an http->socks interface. Your first problem is that the
user-agent (browser) will not be able to use https. The second is that a
proxy server is different from a proxy client. This just forwards http
connections to a socks proxy -- it probably could be modified to go to
other socks proxies than tor. So, it's a proxy-client-glue-layer for old
SW; or it sounds like that.

Here's a diagram to make it more clear:
Firefox->tor->tor-proxy->tor-proxy->tor-proxy->main-Internet->server
Firefox->Orbot->tor->tor-proxy->tor-proxy->tor-proxy->main-Internet->server

Now if all you want is an http proxy on your local computer, Android or
any other, I'd suggest sparing yourself the trouble of modifying Orbot and
going with privoxy. https://www.privoxy.org/

I hope it helps,
David

Hi Natahn,

Thanks for getting back to me.

Well, I am having a few problems incorporating littelproxy 
(https://github.com/mrog/LittleProxy - a proxy server running on 
Android) code into my app. Not that simple, at least for me.

"Every Proxy" from Gorilla Software uses littleproxy as its foundation. 
It seems to work reasonably well on Android. This gives me hope that I 
will be able to resolve my problems.

I have netguard. It's not designed to be used as part of another app. 
There is a lot of "stripping" to be done. It's an option I have not 
ruled out.

I would still prefer to use a proxy server. I think that in the end it 
would give me more flexibility and control.

Thanks,

Alex Donnini

P.S. I have tried a few other open source proxy servers none of them 
successfully (e.g. https://github.com/mileraheel/android-proxy-app)
