i am thinking to write a apk. i will use orbot proxy (127.0.0.1:8118). i can change tor identity on ubuntu (sudo service tor restart). my question is;
can i change orbot (tor) identity from my apk on same device?
(sorry for bad english)
Yes, you can - it's not dependent on APK or other package-style stuff. Just use Tor control protocol and do whatever you need to do over network
