问题
I am trying to test web application in Android 2.3.3 browser. Connection using http://10.0.2.2 results "web page is unavailable". Nothing found in Android Studio documentation.
Does anyone run into the same problem? How did you solve it?
回答1:
You're going to need to connect to your computer's IP.
If you're on Windows open CMD and type ipconfig this will give you your local IP.
If you're on Linux or OSX open terminal and use the ifconfig command.
Since the emulator is a full Android device it has its own network and doesn't use the same hosts file that your machine has. Along with its own IP.
Edit: Grammar fix.

I use my local ip for that i.e. 192.168.0.1 and it works. Verify your local IP.
