Local Proxy Server Running On Android Device

Question

I am trying to write a http proxy server that would run on the device itself. In fact, need to find a way to capture the outbound http traffic generated by the device.

The code I have so far is compiling OK, it is based on the code found here: http://www.jtmelton.com/2007/11/27/a-simple-multi-threaded-java-http-proxy-server/

The problem is that the http request to the actual server would block and never return .

Is there a better way to write such a service without rooting the device?

Answer 1

You should check SandroProxy. Can caputre traffic on non rooted device if os proxy settings are used, or with iptables rules on rooted one. Traffic is stored it in local sqlite database. Captured data can be also examined by chrome devtools. To capture traffic in your app you should check source code for plugins. It has all the code for iptables redirections and proper settings.

Check out the wiki link on google source code HowToInterceptTrafficOnMyOwn

btw: send by sandroproxy support :)

Answer 2

I've been using a piece of software called proxydroid to use my device as a proxy server, and its the only one I've found which doesn't require root. I'm not sure if it will be any help to you, but its an open source project and the code can be found here:

I have noticed that the application will freeze after a while, or if a large number of request are sent at once, but I've not had chance to find out why this is happening.

Forget about setting proxy, use Facebook Stetho library (http://facebook.github.io/stetho/) to review all http requests and responses from emulator/device
