Calling a wcf web service in Android

Question

Hi everybody,

I'm trying to perform a web service call using a simple http request from an Android activity. The problem is that it works when the URL is NOT a microsoft webservice.

I use the following code to call the "http://www.google.com" page and it does work:

package com.android.myapp;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;


public class lltask extends Activity {
   /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button loginButton = (Button)findViewById(R.id.loginButton);
        loginButton.setOnClickListener(loginButtonListener);
    }

    private OnClickListener loginButtonListener = new OnClickListener() {

        public void onClick(View v) {
            EditText alertBox = (EditText)findViewById(R.id.alertBox);

            try {
                // Create a URL for the desired page

                // Read all the text returned by the server
                URL url = new URL("http://www.google.com");
                BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
                String str;
                while ((str = in.readLine()) != null) {
                    // str is one line of text; readLine() strips the newline character(s)
                    alertBox.setText("ok");
                }
                in.close();
            } catch (Exception e) {
                alertBox.setText("no");
            } 
        }

    };
}

So, when I click on the "loginButton", if I get a result, it returns "ok" in the "alertBox".

But, If I try to call this URL, an IOException rises:

http://myserver/Foobar/Services.svc/ReturnFooBar?arg1=foo&arg2=bar

It's very strange because when I type the URL in my browser, I get an answer.

Of course, I added the following line in the manifest:

<uses-permission android:name="android.permission.INTERNET" />

Did somebody try to perform such a web service call?

Thank you,

Regards
