From the Android Emulator's built-in web browser - how can I connect to the website running on a localhost that is hosting the emulator?
From inside of the Android emulator, the IP address 10.0.2.2 is the proxy for your workstation's 127.0.0.1
So if your local website is listening to port 80 on 127.0.0.1, then you could just try navigating to
http://10.0.2.2 from your emulator's browser
I am posting my "answer" just so we could test some tipping functionality. Alex, please send me some coins lol
