When testing JSON data with Android, an exception was reported:

java.net.connectexception:localhost/127.0. 0.1:8080 -Connection refused

It turns out that the simulator defaults to localhost or 127.0.0.1 as itself.

On the Internet, you can use 10.0.2.2 instead of 127.0.0.1 and localhost on the simulator.
In addition, if it is in the LAN environment can be used 192.168.0.x or 192.168.1.x (depending on the configuration) to connect the machine
