We have now completed our Android HTTP Debugging setup and next we will enable the equivalent behaviour on iOS.Almost every application these days seem to communicate over HTTP/HTTPS protocol. On all simulators and devices we can now view OAuth and API HTTPS messages, which can be a big help when we need to troubleshoot. OAuth and API HTTPS Traffic is Now Viewable However, if an HTTP proxy connection is used, requests to occur on the MacBook, so DNS resolution succeeds. To support this I add a local DNS entry on my MacBook:īy default, devices and emulators will not be able to connect to this domain. Our Network Security Configuration file looks like this, and indicates that we will trust all User Certificates installed on the device or emulator:ĭuring mobile development it can be useful to also run the API locally, and I prefer to use a real world API URL such as. To overcome this we need to edit the Android manifest to reference an additional network_security_config.xml file, which will only be active in debug mode by default:

This is due to Trusted Certificate Behaviour in Android 7.0+. In both cases the certificate will then be viewable under Settings / Security / Encryption & Credentials / User Credentials:Īfter these changes, the Chrome Browser will trust the Charles Root, but Mobile Apps will not and we will continue to get a trust error.

Follow prompts to install the certificate.

Open the email and tap the certificate file.

Email the certificate file to the device.

Save the certificate file with a PEM or CRT Extension.

To deploy the root certificate to a real Android device the process is similar, except that you typically need to follow these steps: You may be prompted to set a PIN to secure the device, after which you can see the certificate under Settings / Security / Encryption & Credentials / User Credentials: It will look like the file has not been accepted but you just need to navigate back and forward to view the entry, which you then need to select: Then drag the root certificate onto this screen of the emulator: There will usually be an export option similar to the below, so use it to save the HTTP Proxy Root Certificate to the MacBook’s desktop.įor emulators, navigate to Settings / Security / Encryption & Credentials / Install a Certificate / CA Certificate, then select the below Install Anyway option: To fix this we need to configure emulators and devices to trust the HTTP Proxy’s Root Certificate. This is because the HTTP Proxy is intercepting SSL requests at runtime and replacing the Root Certification Authority: If we now run the system browser or the AppAuth Sample on the Android device, there will be an attempt to proxy the traffic over SSL, and this will result in SSL Trust errors: Be sure to click the menu in the top right and select the Save item to avoid losing edited details. The details for the new entry can then be added in the below screen. If you do need to proxy over a cellular network you need to select Settings / Network & Internet / Mobile Network, then choose Advanced / Access Point Names and add a new entry: This can cause confusion when getting an HTTP Proxy working, so I usually disable Mobile Data so that only WiFi is used: The Android emulator may alternate connectivity between WiFi and Cellular. When running on a WiFi network, select Settings / Network & Internet / Wi-Fi, then choose the specific network connection and click the pencil icon to edit it, then provide proxy details:

For Android emulators, the MacBook IP address is always the special value 10.0.2.2.įor a real device I use the Charles menu item Help / Local IP Address to find my Macbook’s IP address, since I usually run on a WiFi network where the IP address is auto assigned: This value will vary depending on whether you are using an emulator or a device connected via USB. We also need to instruct the proxy to decrypt SSL traffic, as covered in our page on SSL Trust Configuration: Run the HTTP Proxy on the Hostįirst configure and run the HTTP proxy on the MacBook host, as described in our earlier write up on HTTPS Debugging: Next we will focus on viewing HTTPS mobile traffic from emulators and devices on a development MacBook.

Previously we enabled an initial Android Setup and ran the Google AppAuth Code Sample.
