Run v2ray  

v2ray run -c v2ray_config.json

For Android Studio simulator

After turn off the WiFi,

You have to use Kitsunebi(a v2ray core wrapper) to import the v2ray config again.

Then start a global VPN.

Use HTTP proxy

It’s in WiFi advanced setting.

127.0.0.1:10809

More info

yingshaoxo: For some reason, I don’t know why v2ray got two versions of documents, one is Chinese, another is English. And the Chinese version of the docs is clearly different than the English version.

https://guide.v2fly.org/en_US/app/transparent_proxy.html#preparation

By the way, you could use the /etc/hosts to do the same thing: 127.0.0.1 ggboy.domain.local find_a_girlfriend.ggboy.domain.local
