After build android application , I scanned the generated QRcode and install the application on galaxy s4 successfully. But when I try to do some search using the app I got the following exception:

 "java.net.ConnectException: fail to connect to localhost/127.0.0.1(port 8080): connect failed:ECONNREFUSED…."

Please check the attached picture for more clarity.

The app works correctly on simulator. I OFF the firewall of my system but that doesn't solve the issue. Please how can I solve this problem?

This issue applies to: NetBeans 8.0.2, GlassFish Server 4.1, Windows 7, Device: Samsung Galaxy S4

Best regards.

From the emulator, 127.0.0.1 refers to the emulator itself - not your local machine. You need to use ip 10.0.2.2, which is bridged to your local machine.

HTH!
