利用SocksDroid在安卓上翻墙

SOCKS5 client for Android 5.0+ making use of the VpnService API and tun2socks so that it works without root permission (unlike ProxyDroid).
Most of the JNI code are imported from shadowsocks-android project because they have already done most of the work.

THIS IS NOT A SHADOWSOCKS CLIENT! SOCKS5 IS NOT SHADOWSOCKS!

UDP Forwarding

As tun2socks does not support UDP associate but has its own implementation of UDP forwarding badvpn-udpgw, so it is needed that the udpgw daemon run on remote server to use UDP forwarding.
On remote server

badvpn-udpgw --listen-addr 127.0.0.1:7300

And set UDP Gateway in this app to 127.0.0.1:7300

DNS

If the server does not run udpgw, DNS lookups can also be processed in this app.
It makes use of the TCP DNS feature of pdnsd. You just set a DNS server that supports TCP DNS in this app, and all DNS requests will be transformed into TCP queries.

Routing

The app has an embedded list of non-Chinese IPs. Chinese users can make use of it for best experience in bypassing GFW.

GFW

Note that SOCKS5 is currently blocked by the GFW, which means Chinese users cannot connect to any SOCKS5 servers outside China.
But there are still solutions. For example, use stunnel to wrap the SOCKS5 connection with SSL. （意思是用stunnel包裹socks代理服务器程序或http代理服务器程序。参见：

See my project stunnel-android for usage on Android.
