Getting information about the system proxy

问题:

I'm using HttpClient on my android application. Some user can have a system proxy configured on his device. How do I get the information? From this answer I know you can do something like:

DefaultHttpClient httpclient = new DefaultHttpClient();

HttpHost proxy = new HttpHost("someproxy", 8080);
httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);

The problem is that I don't know where to find hostname of the proxy and the port.

Try this:

DefaultHttpClient httpclient = new DefaultHttpClient();

String proxyString = Settings.Secure.getString(getApplicationContext().getContentResolver(), Settings.Secure.HTTP_PROXY);

if (proxyString != null)
{   
    String proxyAddress = proxyString.split(":")[0];
    int proxyPort = Integer.parseInt(proxyString.split(":")[1]);
    HttpHost proxy = new HttpHost(proxyAddress, proxyPort);

    httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
}

I did not test through. Found here.
