扩展功能

扩展了 v2ray-core 的功能:

使用提示

  • 配置文件可使用一个常见的 V2Ray JSON 配置
  • App 使用较新的 v2ray-core 版本,你或许需要确保服务端也升级到相应的版本,具体版本号请看 Release Notes
  • 把配置文件复制粘贴至主界面后,点击连接按钮即可启动
  • 配置文件的 freedom outbound 推荐使用 UseIP 策略
  • 配置文件不需要有 inbound,app 使用了 tun2socks 作为 inbound,并已开启 http,tls 流量嗅探
  • 设备所有 DNS 请求均会由 V2Ray 的 DNS 服务器 来解析,正确设置了 DNS 服务器可以避免 DNS 污染以及 CDN 相关的 DNS 问题
  • 下面是一个可以拿来日常使用的配置模板,在 outbounds 中替换上你的服务器信息即可,其中的路由规则和 DNS 规则从这个 规则集文件 生成:

Build

You must first build/download the tun2socks.aar library from this repo and copy into app/libs, get geoip.dat and geosite.dat from these two repos and copy them into app/src/main/res/raw, don't forget renaming them.

开发相关问题

这个 V2Ray Android 客户端利用 go-tun2socks 把所有的 TCP/UDP 流量转给到 V2Ray 处理,所用的 v2ray-core 是没经过任何修改的官方版本,所以在配置和体验方面不会有太大差别。但在 Android 上有一些东西需要特殊处理,这也是在配置和使用上造成一些差别的地方。

  • UDP 流量在转给 V2Ray 之前,会先在 go-tun2socks 里面经过一个嗅探步骤,如果嗅探出来是 DNS 流量,这些 UDP 流量就不会直接转给 V2Ray,而是把其中需要解析的域名抽取出来再通过 V2Ray 的 DNS 去解析,这时 V2Ray 所用的 DNS 服务器是按照配置文件上的配置来选取,也就是说所用的 DNS 服务器不需要跟原来 UDP 流量的目的地址相同。
  • 在 Android 上有几个情况会造成流量/请求的死循环,目前就我所知的有以下几个:
    • 通过 VpnService 的 TUN 接口读取数据,再由代理程序代为发出时,如果不 protect 代理程序用来发数据的 socket fd,代理程序发出的数据又会被转到 TUN 接口上,这个问题基本可以用 v2ray-core 提供的 RegisterDialerController()RegisterListenerController() 两个接口完美解决
    • 还有一些由 Go 的 net.DefaultResolver 所发出的 DNS 查询流量没有被 protect 起来,在一些特定的情况下也有可能引起死循环
