无法通过Android设备与本地服务器连接

Question

installed XAMPP server, created database and successfully accessed it from chrome browser as well as from android emulator. However whenever i try to run application from my Samsung device, its refusing to connect my IP address.

My IP address is not registered in DNS.

I tried: 1) accessing from url- 127.0.0.1 and localhost 2) modified httpd.conf and httpd-xampp.conf file- changed to Require all granted permission 3) uninstalled my Antivirus 4) changed firewall and proxy setting 5) Created new Inbound Rule in firewall advance security 6) re typed INTERNET permission 7) wrote httpPost.setHeader("Accept", "application/json"); in code

Still Im getting following error:

  W/IInputConnectionWrapper(22232): getSelectedText on inactive InputConnection
  W/IInputConnectionWrapper(22232): setComposingText on inactive InputConnection
  W/IInputConnectionWrapper(22232): getSelectedText on inactive InputConnection

Answer 1

Please try to check your local IP address of your PC. Connect the phone to the same network (WIFI). Then use the following address/port to connect to your PC.

In Android:

URL: your_pc_local_ip

PORT: 80 (but I think it is not mandatory)

I use in this way and it is working properly for me.
