There is another TOR app, InviZible Pro, which you could use that would allow you to force the app through Tor, whether it supports it or not. You can use it as an Orbot alternative or as a Tor Vpn.

This would allow you to apply it system wide or on a per app basis. It also includes DNScrypt, I2P, and a firewall.

I've been using it for over a year now.
