I want to test Https calls from android device using Charles proxy tool. I need to see the raw request/response contents for debugging app. I've configured Charles by adding the host and port under "Proxy Settings" -> SSL Tab. When I run the app, all SSL calls seems to disappear quickly from the Charles. Does any one has any idea how to fix this issue. Charles documentation doesn't seem to have information for Android devices.

The top rated answers are working perfect (a bit old but still working), but I just want to mention that since Android N we all can configure your apps in order to have diff trust SSL certificates (for release , debug only and so on), including Charles SSL Proxy certificate (if you download the Charles certificate and put .pem file in your raw folder). More info can be found here: https://developer.android.com/training/articles/security-config.html
Also the official Charles documentation can be useful to setup this : https://www.charlesproxy.com/documentation/using-charles/ssl-certificates/
Hope this will help to setup Charles inside your app project not on every single Android device.
Edit - this answer was for an earlier version of Charles. See @semicircle21 answer below for the proper steps for v3.10.x -- much easier than this approach too... :-)
For what it's worth here are the step by step instructions for this. They should apply equally well in iOS too:
You should then be able to see the SSL files in Charles. If you want to intercept and change the values you can use the "Map Local" tool which is really awesome:
For me the issue was the IP address that charles was telling me to route to in my proxy settings was incorrect. To solve I ended up going to ifconfig
in the terminal and the trying the different IP addresses (listed next to inet
) at port 8888
for the current active connections
See here:
You would need to install the charles.crt certificate to your device.
refer to: How to get charles proxy work with Android 7 nougat?
From your computer, run Charles:
Open Proxy Settings: Proxy -> Proxy Settings, Proxies Tab, check "Enable transparent HTTP proxying", and remember "Port" in heart.
SSL Proxy Settings:Proxy -> SSL Proxy Settings, SSL Proxying tab, Check “enable SSL Proxying”, and add . to Locations:
Open Access Control Settings: Proxy -> Access Control Settings. Add your local subnet to authorize machines on you local network to use the proxy from another machine/mobile.
In Android Phone:
Configure your mobile: Go to Settings -> Wireless & networks -> WiFi -> Connect or modify your network, fill in the computer IP address and Port(8888):
Get Charles SSL Certificate. Visit this url from your mobile browser: http://charlesproxy.com/getssl
In “Name the certificate” enter whatever you want
Accept the security warning and install the certificate. If you install it successful, then you probably see sth like that: In your phone, Settings -> Security -> Trusted credentials:
Done.
then you can have some test on your mobile, the encrypted https request will be shown in Charles:
For the newer emulator it might be helpful to launch from command line using:
emulator -netdelay none -netspeed full -avd <emulator_name> -http-proxy http://<ip-address>:8888
Make sure you follow @User9527's advice above as well for the rest of the setup
I wasted 1 day finding the issue , my system was not asking connection "allow" or "reject". i though it was due to some certiifcate issue . tried all methods mentioned above but none of them worked . in the end i found "Firewall was real culprit ". if firewall settings is ON , they will not allow charles to connect with your laptop via proxy IP . make them off and all things will work smoothly .Not sure if that was relevent answer but just want to share.
Thanks for @bkurzius's answer and this update is for Charles 3.10+. (The reason is here)
Install Charles Root Certificate on a Mobile Device or Remote Browser...
, and just follow the instruction. (use the Android's browser to download and install the certificate.)Source: Stackoverflow.com
