If you are running behind a corporate proxy with SSL interception, you will need to follow these steps to trust your proxy certificate for HTTPS:

• In Android Studio, Open File -> Settings
  • In Tools -> Server Certificates
    • Tick ‘Accept non-trusted certificates automatically’
    • Also click the ‘+’ and manually add the corporate proxy root certificate.
  • In Appearance and Behaviour -> System Settings -> HTTP Proxy
    • Set your corporate proxy URL and port details
• Download KeyStore Explorer: http://keystore-explorer.org/downloads.html
• In KeyStore Explorer (run as admin), open the Android Studio JRE certificate store: C:\Program Files\Android\Android Studio\jre\jre\lib\security\cacerts
  • The password should be ‘changeit’
  • Import the corporate proxy root certificate, and save.
• In Android Studio, select File -> Invalidate Cache and Restart
