Below, I will demonstrate how to do this for google.com, but it will work for any website accessible on the phone

  1. Connect an Android device to your computer (make sure USB debugging is on).

  2. Open Google Chrome on your computer and go to chrome://inspect to show a list of debug-enabled WebViews on your device.

  3. Click "Inspect".

  4. Select "Security" and click on "View Certificate" as shown in the picture.

  5. Now, drag the certificate icon (you could also drag a root CA certificate or an intermediate one) to your Desktop.

  6. Done.
