Android 127.0.0.1/localhost Connection refused, you should use 10.0.2.2 on the simulator to access your computer native

Debug via Android Simulator simulator link localhost or 127.0.0.1, because I built Apache on the computer, and my code is probably
URL url = new URL (urlstring);
URLConnection urlconn = Url.openconnection ();

But the error!!

Exception 1:java.net.connectexception:localhost/127.0.0.1:8080-
Connection refused

The problem is that the Android Emulator (simulator) takes itself as localhost, that is, the code uses localhost or 127.0.0.1来 access, are all access to the simulator itself! This is not going to work!

If you want to access your computer on the emulator simulator, then use the Android built-in IP 10.0.2.2 bar, 10.0.2.2 is the specific IP set by the simulator, is the alias of your computer aliases alias

Remember, use 10.0.2.2 on the simulator to access your computer's machine
