Exclude host machine from charles proxy recordings - android

I'm trying to capture results from an Android device only, but I keep seeing results from my MAC as well.
I've tried excluding 127.0.0.1 and the address for the HTTP proxy (from Help>Install Charles Root Certificate on a Mobile Device) in recording settings.
I've also looked up the ip address for the phone and enabled only it in SSL Proxying Settings (instead of .)
Suggestions?

1) You should turn off this option in the Charles app:
Proxy > macOS Proxy
2) You can also check that the network adapter you are using does not have a proxy configured:
System Preferences > Network > mark the first connected adapter from the list on the left, e.g.: Wi-Fi and click the Advanced... button > make sure that there is no proxy configured on the Proxies tab
If you see that the localhost is set as proxy, clear the settings:
The first method does the same as the second one, but sometimes the Charles app does not remove properly proxy settings from the network adapter, so you must delete it manually.

If the problem you have is that too many requests make it difficult to find the ones you want to work with you can use the "Focus" option by right-clicking on a request you want to monitor in the requests pane and select Focus. Note that you can focus on multiple hosts.
This will make request from other hosts get grouped under a "Other hosts" entry in the requests pane, so they won't disturb your work anymore.

Internet Connection lost when setting Charles proxy on Android

I am trying to set charles proxy on Android 8.0( S8 ). I have installed the root certificate-> Changed WIFI settings to charles proxy settings. But After connecting to proxy, Internet connection is lost. Tried multiple times. Is there any other security certificate I need to install for Android 8.0. Please suggest. Thanks
The sequence of steps is really important:
Connect the Android device and the computer that running Charles to the same LAN (WiFi) network
Start Charles
Then set the Charles machine LAN IP as manual proxy on your phone. Open the list of Wifi connections, then touch and hold the connected network, and select Modify network.
Proxy: Manual
Proxy hostname: Open the Help > Local IP Address menu in Charles and paste into it the address displayed
Proxy port: 8888 (This is the default value that can be changed in the Proxy > Proxy Settings menu.)
Open a browser on your phone and make some network traffic
After that you have to click into the Charles app window. You will see a confirmation dialog that asking you to allow network traffic from the mobile device, press Allow.
After all, open the https://chls.pro/ssl URL on your device and install the .pem file for VPN and apps (Use Chrome browser on Android, and Safari for iOS devices.)
Troubleshooting
When Charles is the background, the confirmation dialog will not be visible automatically, you have to activate (bring back to the foreground) the Charles application window to see it.
To check the device connection permission, go to Proxy > Access Control Settings. You should also see its LAN IP on the list.
To getting your Android phone LAN IP address open the Dialer and enter: *#*#4636#*#*, then select Wi-Fi information > WiFi status and refresh stats.
If anyone who is still looking for answer then try these steps. It worked for me ☺️
When you enter proxy, there will be one more option that is "Bypass for" in this field enter * as value, and thnx me later.

Eclipse / Android - how to monitor device's HTTP traffic

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!

Genymotion proxy with user/password

I'm running Android through Genymotion using the following configuration:
For the Host-Only I used 192.168.1.213 and DHCP allocates addresses starting with 192.168.1.214
My computer is behind a Squid proxy that has user and password, and address 192.168.1.2 with port 4444
I start the Android VM and in Genymotion Configuration I can see IP Management to be IP 192.168.1.214. I can also ping this address from my computer with success, so all good until here.
If I go to Menu -> Settings -> Wireless & Networks -> Wi-Fi -> WiredSSID -> Modify Network, I see IP address 10.0.3.15 - why is that?
Also, if I try to configure proxy, all I get is host and port, but no options for user/pass, so when I try to access a page in the browser, it says that proxy authentication doesn't work.
Is there a way to configure Android to work through my proxy? If so, what should I configure?
Thank you
Your IP configuration looks correct.
There is two connection between genymotion and your host.
The first one is only technical, to allow Genymotion to run (host
only).
The other one is the one that will be used when trying to get
internet from Genymotion. (NAT)
In Genymotion Settings, under proxy settings, you will be able to set your username & password for your proxy.
If you want to do more complex authentication schemes, like NTLM or Kerberos, Genymotion won't work. But as a workaround, you could use tools like Cntlm, or NtlmAps, that will provide a local, non authenticated, proxy and take care of upstream proxy authentication for Genymotion.
This settings will only work for the sofware Genymotion.
Inside Android, you will also need to set a proxy in the settings.
Go to: Settings -> Wi-Fi -> Long Click on "WiredSSID" -> Modify network -> Check "show advanced settings".
As mentionned there, the proxy will only works for the Browser, and maybe Gmail also.
You will need to set it also on the settings of each app you trying to use.
Not all of your apps will provide a proxy setting. I think Twitter does, but if your app doesn't provide one, you're screwed!
I found a much simpler solution.
All you have to do is to create a rule in proxifier which will let genymotion to use the host default ip. In this way it will manage to connect to the oracle virtual machine ( which has no problem with working with proxifier; obviously, in proxifier you will setup your proxy with its authentication credentials).

How to catch non-browser traffic on Eclipse Android Emulator through Fiddler

I want to look at trafiic on Android Emulator in Eclipse through Fiddler.
Capturing on all processes is still missing non-browser trafiic. My Emulator Android have proxy setted to my local machine but i see ony Browser traffic.
You may have gone through these same steps, but here is what I did to get it to work. I pieced together info from different sites including Fiddler2.com:
In Fiddler, click Tools / Fiddler Options / Connections and ensure that the box Allow remote computers to connect is checked. (Restart Fiddler if this box wasn't already checked .)
Then Note the IP Address of the Fiddler PC; you can see this by hovering over the icon in Fiddler's toolbar: (it's just the IP of your pc):
Then on the emulator go to Setting->Wireless&Networks->Mobile Networks -> AccessPointNames. I used the existing APN (T-Mobile US) and just changed the Proxy and Port.
Proxy is just the IP from previous step (I did not need to enter http://)
Port is 8888
Restart the emulator and you should see your app traffic in Fiddler.

How can I connect to a proxy on Android?

I have a Samsung Galaxy S, running on Android 2.2
I want to track all HTTP requests (from both browsers AND apps) with Charles (proxy installed on my computer).
I would like it similar to how it is on the iPhone where you go to settings, wifi, and on the right connection you can select the HTTP proxy settings
You can do it with Wireshark: http://www.wireshark.org/download.html
Here are instructions for Mac + Android device:
Launch Terminal and run the following commands:
cd /dev
sudo chmod a+r bpf*
Connect to the internet using an Ethernet cable
Click on the Airport/Wi-Fi icon at the top right of the screen and select Create Network; remember the name you give this network
Go to System Preferences, open the Sharing pane, highlight (but don’t check) Internet Sharing
Select Share connection from: Ethernet, To computers using: check AirPort/Wi-Fi
Click AirPort/Wi-Fi Options, and enter the network name you chose above (it should be displayed automatically, so just click OK)
Check the Internet Sharing box
Click Start
Connect your Android device to the network you just created
Launch Wireshark
From the menu, select Capture -> Interfaces. Click on Options next to en1 (or whichever one shows a Wi-Fi icon)
Click the Capture Filter: button
If you want, choose one of the filters, such as HTTP TCP Port (80) and click OK
Click Start
There is currently no out-of-the box proxy in Android. Several alternatives are discussed in this page. Also google for "Android proxy" to see what other alternatives are out there.
ProxySelector
Some alternatives to have partial support of proxy in Android are listed here: http://issue1273.blogspot.com. There is also an Android Proxy Library that try to abstract the access to proxy settings for every Android version.
A very nice write up on the procedure for setting up Charles with Android can be found here, including installing the certificate so you can also debug / proxy your SSL traffic:

Since Android Studio 3.0 release, android now support setting proxy natively.
See documentation.
