Question

I am trying to connect a WCF service hosted at my local IIS express from an Android app. Currently, I am testing this on an Emulator.

Local URL for the service is <

Answer 1

I tried something else which worked , I added the IP address of my system within the IIS Express applicationhost.config file bindings sections.

<bindings>
<binding protocol="http" bindingInformation="*:40000:localhost" />
<binding protocol="http" bindingInformation="*:40000:192.168.5.118" />
</bindings>

I am able to call the service now

Answer 2

Add Internet Permission, Network State, and Wifi Permission in AndroidManifest.xml

Answer 3

As I understand it, 10.0.2.2 is an alias for 127.0.0.1, so add that to your applicationhost.config binding for your site, e.g.

 <site name="MySite" id="1">
    <application path="/" applicationPool="Clr4IntegratedAppPool">
      <virtualDirectory path="/" physicalPath="{yourpath}" />
    </application>
    <bindings>
      <binding protocol="http" bindingInformation="*:26013:localhost" />
      <binding protocol="http" bindingInformation="*:26013:127.0.0.1" />
    </bindings>
  </site>

Bear in mind that these days if you're using Visual Studio the relevant applicationhost.config for your site may not be in c:\users\... but rather in a .vs\config folder at the root of your solution.

Answer 4

1. What's with "port 40000"???????
   I'd definitely try a lower port number (like something below 32768 ;))
2. Make sure your androidmanifest.xml has internet permissions
3. Make sure "api/authenticate" is defined and available in IIS
4. Make sure Windows firewall isn't blocking port 40000
5. Useful tools include:
   • ping (so you can "ping 10.0.0.2"; available in OOTB Windows)
   • telnet (so you can "telnet localhost NNN"; you must add this in Windows Features)
   • Firefox and Firebug
   • Wireshark
