failed to connect to localhost/127.0.0.1 android

Question

I am new to android development, and trying to call local .NET web api service in android via retrofit library. After starting my web api on IIS I am getting this error failed to connect to localhost/127.0.0.1 android.

When I did same thing as suggested http://themakeinfo.com/2015/04/retrofit-android-tutorial/, It's working fine, But my localhost service is not calling up from android

My service url is, http://localhost:52511/api/Values/getAllStudents/5

and it is giving me output in XML format in browser too.

I have also try to call it with,

public interface gitapi {
    @GET("/api/Values/GetProduct/{id}")      //here is the other url part.best way is to start using /
    public void getFeed(@Path("id") int id, Callback<gitmodel> response);
}

public class gitmodel {
    public int studentId;
    public String studentName;
    public String studentAddress;
}


String API = "http://10.0.2.2:52511";
public void CallService(View view){

        RestAdapter restAdapter = new RestAdapter.Builder().setEndpoint(API).build();
        gitapi git = restAdapter.create(gitapi.class);

        int id = 5;
        git.getFeed(id, new Callback<gitmodel>() {
            @Override
            public void success(gitmodel gitmodel, Response response) {
                Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_LONG).show();
            }

            @Override
            public void failure(RetrofitError error) {
                Toast.makeText(getApplicationContext(), "Errors", Toast.LENGTH_LONG).show();
            }
        });
}

but no luck.

Please tell me where do I need to change to make it work. ?

Response I am getting in browser is,

<ArrayOfstudents xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/APICall.Controllers">
<students>
<studentAddress>valsad</studentAddress>
<studentId>1</studentId>
<studentName>Keval</studentName>
</students>
<students>
<studentAddress>Hyderabad</studentAddress>
<studentId>2</studentId>
<studentName>Honey</studentName>
</students>
</ArrayOfstudents>

Answer 1

There's nothing to do with retrofit library in your case.

It's about your network settings, your phone and IIS server must be the same LAN.

You can follow as below.

1. Launch an AP on you IIS server;
2. Connecting the AP with your phone.

Sometimes you need to close security firewall on your IIS server.
