As of Android 7.0 no custom certificate will be used by android apps. App developers need to specifically write codes and change app settings to follow a custom CA.
But this is difficult while testing for certificate pinning in a UAT environment. As a solution I wanted to add the custom CA certificate of my proxy tool (burp or ZAP) to androids system folder.
How to do this? To which folder the certificate needs to be copied? I am using an emulator. So is there a way to do this without rooting the emulator?
