In the logcat it said No Route to host what does this means? I try open the URL in my browser everythings works fine, just that when my android application trying to connect it, then it forced close my application.
here explanation :
Your 192.168.1.10 address is a DHCP address (dynamically) assigned by your router to your PC. As a result it is visible to the emulator.
Thanks
