Get xml from a php webservice url using android

Question

I want to read a xml from a service url, I wrote the code, my url is ok, seen from browser,

    public String getXML(){
    String line = null;
    try {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpGet httpPost = new HttpGet("http://localhost/simplewebservice/index.php?user=1");

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        line = EntityUtils.toString(httpEntity);
    } catch (Exception ex) {
        Log.d("Error reading xml", ex.toString());
    }
    return line;
}

But it gives me the following error java.net.SocketException: Permission denied. Can anyone have a better solution for this?

Kind regards,

Pritom.

in your manifest.xml add this description

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

because it doesn't work with localhost or 127.0.0.1 u should change ur local ip adress for exemple 124.0.1.1 or anything else!

or if you can paste your page (index.php) on internet it will work certainly!

How can I change my local ip address? I am now confused and dont get any suggestions from google.

do this and it will let you change/save your hosts file. 1) Browse to Start -> All Programs -> Accessories 2) Right click "Notepad" and select "Run as administrator" 3) Click "Continue" on the UAC prompt 4) Click File -> Open 5) Browse to "C:\Windows\System32\Drivers\etc" 6) Change the file filter drop down box from "Text Documents (.txt)" to "All Files (.*)" 7) Select "hosts" and click "Open" 8) Make the needed changes and close Notepad. Save when prompted.

I am sure that your using emulator.

Andriod emulator is separate virtual machine by itself. If we provide localhost/127.0.0.1 as a hostname, then emulator will try to search url within its environment. To avoid this problem, we need to provide the ipaddress of local machine.

Pls note that machine name as a hostname will also give problem.

127.0.0.1 refers to localhost in the Emulator, not your machine.

Use 10.0.2.2 to connect to your host machine.

Can u please tell me how can I change my localhost ip address?

He is not saying change your localhost's IP address. He is saying use HttpGet httpPost = new HttpGet("10.0.2.2/simplewebservice/index.php?user=1"); instead of HttpGet httpPost = new HttpGet("localhost/simplewebservice/index.php?user=1"); -- This will connect to your HOST computer (windows / linux / mac) instead of your emulator.

If you were running from tablet onto a local LAN to connect to a server would it be 192.168.1.2/index.php? 192.168.1.2 being the ip address of the server.
