Either I need to change my model object in run-time or update the server. As long as you’re configured properly, you should see those SSL request details from the domains you specified in Charles’ SSL Proxying Settings.įeel free to discuss your results and let me know if I missed anything obvious.Being software developer, unit testing the code for different sets of data is important. Now that you’re set up, you should see Charles recording traffic from your device. Read all about the new features here and if you can’t wait for a stable release, 3.0 is currently available in the dev channel. In addition, Android Studio 3.0 will now allow managing proxy settings for your emulator images. In the Android emulator run configuration add an Additional Emulator Command Line Option: -http-proxy Where LOCAL_IP is the IP address of your computer, not 127.0.0.1 as that is the IP address of the emulated phone.ĮDIT: Thanks to Brandon Davis for pointing out that the full command would be emulator -avd EMULATOR_NAME -http-proxy IP_ADDRESS:PORT ![]() Using An EmulatorĪccording to Charles’ site you can start the emulator with a flag in order to use the proxy. You can always set the network configuration back to “Proxy: None” once you’re done debugging. Note Until you remove the manual proxy from this device’s wifi configuration, whenever you use this network again you will need to have Charles open and running on the same IP address. Once that process is complete, you should be ready to debug some requests. You’ll need to make note of the HTTP Proxy Port that is specified.Īfter you’ve named the certificate and tapped “OK”, you will either be prompted to input your device’s pin/password or prompted to set up your device’s pin/password. Open up Charles on your Mac and then open Proxy > Proxy Settings from the toolbar. View raw network_security_config.xml hosted with ❤ by GitHub Setting Up Charles Specifying the res/xml/network_security_config.xml file: View raw AndroidManifest.xml hosted with ❤ by GitHub Specifying the android:networkSecurit圜onfig property within your AndroidManifest.xml file: There are a few different ways of adding your certificate to the application’s trusted configuration, but I found that the easiest was not to include Charles’ certificate within my application code, but to simply trust the user-installed CA certificates (like previous versions of Android used to do). To ensure Android trusts the certificate, you’ll need to specify a Network Security Configuration for your application. If your test device is running Android 7.0 or newer, there are a few extra steps to ensure that you are able to trust the Charles CA Certificate. If not, feel free to correct me so that I can update this post. I admittedly haven’t needed to do any proxy debugging without a test device, though.Īlso, as of this post, we are targeting Android SDK version 25 in our applications, but this specific setup should work with all versions. Luckily I have now done this enough times to feel good about writing it up.įirst off, this setup will not work on an emulator without an additional step (see below). It turns out that this is possible, but requires a bit of work. The requests I wanted to check happened to be protected by SSL, so in addition to adding the proxy information to my device’s networking configuration, I also needed to install Charles’ root certificate. I figured it would be similarly helpful to debug some of the requests we were making from our apps without logging out to Logcat and cluttering our app code. Lately, however, I’ve been doing a lot more work on Android apps than I have on server-side applications. This includes requests, responses and the HTTP headers (which contain the cookies and caching information). I’ve been a longtime user of Charles for checking requests and responses from the web applications I write.Ĭharles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet. ![]() The following is from Odd Networks, Erik Straub Using Charles Proxy to Debug Android SSL Traffic
