I recently update my device to Android Nougat and found that i'm not able to all content of the traffic on my charles proxy, and when I used marshmallow/Lollipop devices, I can still see what I want to see.
Based on this Android Security Config, We have the control of the certificates we want to trust for the application we own. ( we need to add this config file into manifest.)
How about other nougat applications (api>=24) ? How can I see other nougat applications' traffic content? is there a way to do so since we don't own the application, there is no way for us to trust certain self-signed cert.
