CoreI/Status.go中的getDataDir()函数可能需要修改

Android 6.0以后系统支持多用户,分别为"主要用户"、"次要用户"、“访客”。以前的手机用户内置存储区在/data/data/packagename/中。但是现在的用户内置存储区在/data/user/userId/packagename/目录。比如，“主要用户”的userid为0，则它的私人内部存储区在/data/user/0/com.v2ray.ang/目录，而第一个“次要用户”的userid为10，它的私人内部存储区在/data/user/10/com.v2ray.ang/目录，以此类推。手机/data/data/packagename/目录仍然存在，应该是为了兼容性考虑，但是这个目录只有“主要用户”可以访问。所以导致了“次要用户”安装这个应用的时候，无法成功启动vpn服务。通过logcat可以看到，提示“fork exec /data/data/tun2sock : permission denied”。
希望作者能修改这个问题，让多用户的手机也可以安装使用。

获取用户内部存储目录有相关函数，但方便起见我做了如下修改，并测试，已经测试通过。“主要用户”、“次要用户”都可以成功运行。用户的userid可以通过uid/100000得到。CoreI/Status.go中的getDataDir()函数修改如下：

func (v *Status) getDataDir() string {
var datadir = "/data/data/org.kkdev.v2raygo/"
if v.PackageName != "" {
datadir = "/data/user/" + strconv.Itoa(os.Getuid()/100000) + "/" + v.PackageName + "/"
}
return datadir
}

编译出的东西能兼容Actinium吗？

虽然Actinium凉了很久
还有就是有具体编译教程吗
我编译总报错怀疑是环境变量不对

请问#lib2ray这个配置信息是什么

在conf目录里conf_vpnservice.json conf_ws_vpnservice.json config_mobile.json三个配置文件中的#lib2ray里配置的是什么信息

真机上可以正常运行，在多款模拟器运行进程会被杀

在模拟器（Nexus 6P API 27(Android 8.1.0,API 27)）上运行一会之后，vpnservice会被杀，期间网络不能正常访问。已测试多款模拟器，都出现该情况。但真机实测是正常的。出现的崩溃日志如下：

配置文件vpnservice中26.26.26.1和26.26.26.2这样的地址是什么意思呢

原issue在这儿。 [https://github.com/RayFantasyStudio/V2Ray-Android/issues/10]

为了搞清楚移步到这儿了。可以说明一下吗，谢谢

is missing DT_SONAME will use basename as a replacement 错误

LoadJNI里 System.loadLibrary("gojni")加载so库时报错
is missing DT_SONAME will use basename as a replacement: "libgojni.so"

貌似不支持x86模拟器运行呢，能把x86架构编译进库里吗？

这个里面的V2RAY的版本能否跟V2RAY的版本基本同步。

建议修改 DNS 解析方式

见 2dust/v2rayNG#26

inbound inbounddetour 可不可以不要写死

v2rayNG引用的这儿的库，但是开发反应是这个库把inbound给写死了，自定义json里面的inbound以及inboundDetour没法设置

感谢

v2ray 3.11 releases 版本没提交到 Play上吗？

How about ship dnscache replace pdnsd?

I see android libv2ray shipped with pdnsd.

How about ship dnscache bind with libv2ray?

I am the author of dnscache https://github.com/netroby/dnscache

It was a very small dns cached resolver written with golang.

libv2ray using gomobile, i thought it will be very easy to integrate with my dnscache.

libv2ray处理DNS请求的方式有问题

在Android中，开启VPN后，OS仍会负责发起域名解析请求。libv2ray会将DNS请求当作UDP报文直接进行路由，而在默认使用8.8.8.8访问geoip:cn的情况下，在远端发送DNS请求会导致返回不适合本地的IP地址，导致网页访问缓慢或者返回了面向海外的页面。而在PC上，Socks客户端向服务端发送的只有域名信息，域名的解析由v2ray全权负责。tun2socks虽然将tun界面转换为了socks界面，却并不能良好的处理DNS请求，导致DNS请求全部被无脑转发、返回了不适合直连的CDN。比如，通过Actinium访问淘宝，在全局代理下会被重定向到国际版，而在PC上是正常的。原文一开始发在了v2ray/core下，但我感觉应该是libv2ray的实现方式有问题，和v2ray本身应该没有关系。所以稍加编辑、发在了这里。

环境：

服务器端：2.47
PC端：2.47，传入连接使用Socks协议。
Android端：2.50+libv2ray 25+Actinium。

下面是我的猜测。
首先，Firefox在创建连接时是直接向v2ray发送的域名，本身并没有生成DNS请求。Socks协议允许客户端建立TCP连接时直接请求域名而无须预先将域名解析成IP地址，而Firefox则完全没有参与域名的解析过程，在访问某个页面时只是把域名直接发送给了Socks服务器。若访问的域名属于geosite:cn，则wireshark中可发现对该网站的DNS请求。若访问的域名不属于geosite:cn，wireshark中就不能发现对该网站的DNS请求，而v2ray的log中可见通过隧道向8.8.8.8:53发起的的DNS请求。真正生成DNS请求的应该是v2ray本身。V2ray将会通过路由规则来选择将DNS请求送给OS中设置的DNS服务器或v2ray的配置文件中指定的DNS服务器。

PC环境下Wireshark所获取的Socks报文如下。

Transmission Control Protocol, Src Port: 14696, Dst Port: 1082, Seq: 1, Ack: 1, Len: 3

但是在Android平台上，建立TCP链接的流程与PC+Firefox+v2ray有者很大的差别。libv2ray是通过tun2socks将隧道设备转换为socks链接的，而Android OS本身依旧在按照正常的流程（DNS解析、建立连接）对外建立TCP链接，所有的DNS请求都是由OS本身发出的，v2ray本身只能将DNS报文当作普通的UDP报文、按照路由设置机械的转发。Android在建立连接时将会直接使用IP建立连接。

因此v2ray在这个情况下就不能将域名与按照路由规则送给不同的服务器解析。如果DNS设置为海外的服务器就会导致淘宝返回海外版页面。即使是设置了domainOverride也只能是在建立连接时再通过嗅探选择直连或走隧道，无法解决问题。

what is the asset fileDir on the gomobile?

hello, could you please say the meaning or according of this dir? @xiaokangwang https://github.com/xiaokangwang/AndroidLibV2ray/blob/master/interact.go#L288

请问是怎么调用android的vpnservice的？

不是很了解V2ray，纯粹是为了看看用golang怎么在Andorid里面调用VPN service而不需要手机root才能使用vpn。AndroidLibV2ray用go get 拿不下来，也没有详细的readme告知怎么用。

看代码是不是主要在 EscortRun 里面创建vpn的？ file := os.NewFile(uintptr(tapfd), "/dev/tap0")，这个用法貌似不能在非root的android里面成功吧？而且跟官方文档的做法不太像： https://developer.android.com/reference/android/net/VpnService.html, 那里讲是要用Builder， prepare，establish等过程...

请你能解释一下你是怎么做的吗？

谢谢

the purpose of using unix.Connect and its FileConn?

hello, could you please say the purpose of specifying the unix socket to return the conn? i found the simply net.Dialer.Dial done this as well.

great thanks for this repo.
