Proxifier for android apk 20166/22/2023 ![]() Android's linker does support LD_PRELOAD, see Termux-exec for instance. Though this approach is more relevant to native libraries and not Android's Java stack (where apps run), apps can be hacked to start with specific LD_PRELOAD values. Proxifier and Prox圜ap do something similar on Windows. This library is modified to offer the same functions as the OS socket layer, but transparently translating plain connections to proxied connections by effectively taking control of functions/syscalls related to networking ( socket, connect in particular). Dynamic linker searches for required symbols in this library first. When a dynamic binary is run for some network communication, LD_PRELOAD variable is used to force load a specific dynamic library in memory before any other shared libraries. Just as a reference, Shared library interceptor is a popular hack in Linux world (used by socksify, tsocks, torsocks, proxychains etc.). See this answer for other proxification methods. Drony and Postern use Java based similar methods. In latter case root is not required because apps (like SocksDroid, Orbot, Shadowsocks and many other firewalls / sniffers) use Android's Java VPN API. Two common methods are redsocks + iptables and tun2socks + VPN/routing. So we need third party apps / native tools which use different approaches. Redirect traffic from whole device or specific apps towards proxyĮvery app doesn't have built-in support to use SOCKS proxy, only a few apps such as web browsers have. Drony and Postern can also create shadowsocks tunnels. Both listen on SOCKS5 as well as transparent proxy ports. Shadowsocks and Orbot (Tor) are two more examples of encrypted tunnels. Ki4a has a builtin interface for SSH login to create a Dynamic Forwarding tunnel that acts as a local SOCKS proxy. In latter case the proxy is running usually on the client device itself or on local network. Proxy can be a standalone server or secure tunnel. HOW TO SOCKSIFY:Īpps force all traffic towards a SOCKS proxy in two parts:Įstablish a connection between client device and proxy server A VPN is also an encrypted tunnel but it operates even below SOCKS, therefore able to carry all IP traffic and forward every port. A common application of latter case is encrypted SOCKS tunnels like SSH dynamic forwarding, Tor, shadowsocks, stunnel, ssf, sshuttle, obfsproxy and so on. socks can be used by individual clients or can be set system-wide i.e. However the connection isn't secure like https and the security depends on initial authentication during handshake. SOCKS proxy - a complete handshake protocol - creates a tunnel at lower level than application proxies ( http/s) in OSI model, so UDP traffic can also be transported. ![]() See details in How to set Wi-Fi HTTPS proxy, not HTTP, via adb shell? HOW PROXY WORKS? So if an app - unlike web browsers - cannot be configured to use SOCKS proxy, there is no way to set SOCKS5 proxy from adb shell or terminal emulator without using a third party tool / app. However there is no built-in support for SOCKS. Android does have HTTP(S) proxy support built-in that can be set through Settings UI and/or command line, but it isn't global, so regarded by proxy-aware apps only.
