Using WebView setHttpAuthUsernamePassword?

I'm trying to do basic authentication to view a protected url. I want to access the protected url which looks like this:

http://api.test.com/userinfo/vid?=1234

So I do the following with a WebView:

mWebView.setHttpAuthUsernamePassword("api.test.com", "", "[email protected]", "mypassword");
mWebView.loadUrl("http://api.test.com/userinfo/user?uid=53461");

but the authentication doesn't seem to work, I'm just getting an output error page. Am I using the WebView method correctly here?

Update: Trying with curl:

curl -u [email protected]:mypassword http://api.test.com/userinfo/user?uid=53461

and it pulls the page fine. I tried every combination of the host parameter, the owners of the api don't know what I mean by 'realm' though (and neither do I) - what info could I give them to help this along?

Thanks

Another option is to use a WebViewClient;

webview.setWebViewClient(new MyWebViewClient ());

private class MyWebViewClient extends WebViewClient {
@Override
public void onReceivedHttpAuthRequest(WebView view,
        HttpAuthHandler handler, String host, String realm) {

    handler.proceed("[email protected]", "mypassword");

}
}

webview.setWebViewClient(new WebViewClient () {

    public void onReceivedHttpAuthRequest(WebView view,
            HttpAuthHandler handler, String host, String realm) {

        handler.proceed("login", "pass");
    }
});

The default behavior of a WebView is to discard all authentication requests. Even if setHttpAuthUsernamePassword.

You have to set a WebViewClient and Override the method onReceivedHttpAuthRequest
