How do I avoid getting "No peer certificate" error when connecting to this HTTPS site on Android?

I am developing an Android application which needs to access QuickPay's service ("https://secure.quickpay.dk/form") through an Http-client. But I keep getting errors when accessing the page. More specifically I get a "No Peer Certificate" error message. I tried several different things already: I tried adding the root certificate to my keystore, and to use this keystore when connecting, following this procedure: adding certificate to keystore. I also tried accepting all certificates, following the proposed method from here: accepting certificate for android. I have successfully connected to other https sites, but can not seem to connect to this one. I have tried on different Android devices (1.6, 2.2, and 2.3.3). Can anyone succeed in connecting to quickpay's site, or can anyone come up with a possible solution/fix?

//Update: If I access this site with my WebView: payment window examples, and press one of the buttons (which basically just launches a http post with some pre-defined variables) I am able to connect to the site in the webview on Android 2.3.3. Furthermore, I found out that I get a reply from the site if I try to launch the above application on Android 3.1! Any suggestions?

public class MyHttpClient extends DefaultHttpClient {

final Context context;

public MyHttpClient(Context context) {
    this.context = context;
    loadHttps();
}

private void loadHttps() {
    String url = "https://secure.quickpay.dk/form";
    HttpPost httpPost = new HttpPost(url);
    try {
        System.out.println("Executing");
        this.execute(httpPost);
    } catch (UnsupportedEncodingException e) {
        System.out.println(e.getMessage());
    } catch (ClientProtocolException e) {
        System.out.println(e.getMessage());
    } catch (IOException e) {
        System.out.println(e);
    }
}

@Override
protected ClientConnectionManager createClientConnectionManager() {
    SchemeRegistry registry = new SchemeRegistry();
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    registry.register(new Scheme("https", newSslSocketFactory(), 4开发者_运维百科43));
    return new SingleClientConnManager(getParams(), registry);
}

private SSLSocketFactory newSslSocketFactory() {
    try {
        KeyStore trusted = KeyStore.getInstance("BKS");
        InputStream in = context.getResources().openRawResource(R.raw.test);
        try {
            trusted.load(in, "mysecret".toCharArray());
        } finally {
            in.close();
        }
        SSLSocketFactory sf = new SSLSocketFactory(trusted);
        return sf;
    } catch (Exception e) {
        throw new AssertionError(e);
    }
}

}

Just to sum up, I fixed this issue by sticking to the WebView approach. The interaction with the API was moved to a server, creating an intermediate communication point which handles the certificate issues. Not the most elegant solution but it works :)

This is very mysterious. The only way an HTTPS/SSL server can avoid sending a certificate is if both sides agree to operate the SSL connection in reverse, where the server is the SSL client and the client is the SSL server, so the certificate travels in the other direction. But I can't see anything in your code that enables that mode, and it would have to be enabled at the other end too. And you would have to be providing a certificate yourself from your keystore ... Very strange.

Try using UrlConnection class to make connections, and see whether you can avoid this "no peer certificate" error.
