I have my device connected to debug Android apps, but I need to see the HTTP requests and responses (inc. header info).
I've seen a similar question asked on how to do this for an emulator, but how to do this when a real device is connected?
You can use Charles, is a really powerful tool that does exactly what you need.
Charles allows you to sniff the packets sent through HTTP from your actual device, the way you use it is simple:
Download and install Charles, run the program and specify the proxy port
Connect the Android Device to the very same network of the computer running Charles
Go to Wifi-Settings in Android Device and long tap on the network connected, then go to Modify Network-> Show advanced Options
Set Proxy as Manual and in Proxy Host name set your computer IP "192.xxx.x.x" and in the Proxy port add the same port specified in Charles Proxy Settings.
And that's it, all the traffic from your phone will be proxy to charles and it will show you headers, parameters, etc...
Hope it Helps
Regards!

I am on windows 10 laptop which has two network interfaces (10.* and 192.)( one assigned by the router and another by a VPN virtual adapter). When I start Charles Proxy, it by default starts listening on the 10.* interface. Is there a way I can make it listen on the 192. interface`?
Following is the screenshot of the issue I am facing. Without Charles Proxy listening on the 192.* ip, I cannot get my Android devices to proxy via the Charles despite adding the required Proxy settings on the Android device.
I figured that changing the metric order of the nw interface allows charles to pick up the desired interface. Also, the corporate firewalls were blocking the inbound proxy connection requests on port 8888.
The following command on windows showed me the open ports and I used one of the open ports to configure Charles and now its working as expected and allowing Android\iOS devices to connect.
c:> netsh firewall show state
I'm trying to reverse engineer one Android app's traffic and it's using sockets, xmpp or something else, but not http(s) on some features. I know this because Charles does not see some requests, but data is definitely coming from the server for sure (e.g. chat messages).
Android allows to set http(s) proxy, not socks. ProxyDroid doesn't work on genymotion, because it's x86 and ProxyDroid doesn't support that. Tried Drony app on genymotion, which supposedly should allow socks proxy, but once I try turning it on, the whole emulator restarts (probably crashes).
So how do I sniff/trace/inspect sockets traffic on Genymotion/Android emulator?
You might have better luck by doing it on the host side, ie from the Windows/Mac/Linux machine running Genymotion.
The basics
Install Wireshark
Start Wireshark and select the network interface which connects you to the Internet (or to the server you are interested in). For me it is wlp1s0.
Tell Wireshark you only want traffic going from your device to the server you are interested by entering ip.dst == <server-ip> in the filter line. Now go back to your device and use the application which communicates with the server. Traffic should appear in Wireshark. Here I am browsing my web site, whose IP address is 5.135.144.176:
Note that if Wireshark knows about the protocol used by the server, you can filter it. Here is the same output with the http filter:
Watching only traffic from the device
With the current setup, if you access the server from your host, this traffic will be logged by Wireshark as well. To avoid that you need to do the following:
Configure your device in Bridge mode: stop the device, open its settings dialog and select Bridge:
Get the device IP address: restart the device, open the "Settings" application and go to "About phone > Status", note the IP address:
Add this IP address to the filter line in wireshark, like so: ip.src == <the-device-ip> and ip.dst == <the-server-ip>.
my app is sending some http request, and I want during test step to get all requests and responses.
In browser I was used BrowserMobProxy to get all responses but it's look like it's work just on browser.
Is some one know how can I get responses from app in test step ?
You can re-route all connections through a proxy running on your development PC.
Note that I assume that you have a local Wifi router and a local network both your computer and the Android phone are connected to.
All you need is that the IP of your development PC is accessible from the Android phone you use for app testing.
On the PC install a inspection proxy like Fiddler (Windows), Burp Suite (Java) or Charles proxy (OSX).
By default most proxies only listen on localhost connection, but they can be configured to accept connections from other computers (or in this case an Android phone).
For Fiddler you find it in menu Tools -> Fiddler Options -> Tab Connections -> Allow remote computers to connect.
Configure it accordingly and then change the Wifi setting on the Android phone for the used Wifi network.
Enable the manual proxy configuration and enter your computer's IP address in your local network and the port number the proxy is listening on.
After saving the new Wifi settings all apps on the Android phone should use the proxy on your PC, which will allow you to see also the traffic of your app.
I've connected my Android device to my PC wi-fi using an application called Connectify , which make it easier to browse the internet using PC'S internet connection , when I did make connection to a web server using my android device , Fiddler didn't capture the traffic .
I am using windows 7
Routing my Android Wi-Fi connection to a proxy doesn't work , my router redirects all requests from local network to the Log in page to the router settings
To monitor the network traffic of an Android device using fiddler
Open Fiddler on your pc
Go to Tools >Fiddler Options >Connections. Make sure 'Allow remote computers to connect' is checked'.
In your android device, go to your wifi settings, long press on your current Wifi and click on 'Modify network'
Click 'Advanced Options' and set proxy to manual.
Under 'proxy hostname', enter the local IP of your computer.Under 'proxy port', type '8888' (this is the default port that fiddler listens on)
Now, you should be able to see the Android network traffic on your fiddler.
Hope this helps :)
First of all, do not use the Connectify. Uninstall it.
Follow the exact instructions on the fiddler documentation. It has screenshots for setting up the proxy and everything.
Make sure that your PC shares its internet connection when you first connect it to your wifi network.
Do not attempt this at a coffee shop or in an hotel, where wifi isolation is often practiced as a security measure.
It goes without saying, do not forget to turn off the mobile data of your android device.
How can I direct all android data traffic excluding calls and SMS through a proxy server before it actually reaches its destination, I was able to retrieve and edit some system information like the net.eth0.gw. Will that help and if so, what exactly should I do with it? I'm very new to android and networking, any help will be appreciated.
Thank you.
You can direct your Android to use a Fiddler proxy. Or any HTTP proxy for that matter.
I do this from time to time on my Android phone for debugging HTTP network traffic. And that covers about 90% of everything you could think of needing to capture.
Setup Fiddler on your PC and enable it as a proxy server for other nodes. From the Fiddler Tool's menu, select Fiddler Options, and then Connections Tab. Then enable the "allow remote computers to connect" checkbox.
Then configure your Android device's Wifi settings such that a manual proxy setting is specified for the current Wifi connection. (You give it your PC's IP address at port 8888).
Then browse some websites on your phone. You should see the request/response flows in the Fiddler window.
This obviously only works for HTTP traffic - for code that uses the typical class libraries built into the connection. It doesn't work for code using sockets. Anything over HTTPS will be hard to view since its encrypted, although Fiddler has a few options that you can try (YMMV).
