Get xml from a php webservice url using android

问题

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.

回答1:

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.

in your manifest.xml add this description

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