Https Connection Android

I am doing a https post and I'm getting an exception of ssl exception Not trusted server certificate. If i do normal http it is working perfectly fine. Do I have to accept the server certificate somehow?

I'm making a guess, but if you want an actual handshake to occur, you have to let android know of your certificate. If you want to just accept no matter what, then use this pseudo-code to get what you need with the Apache HTTP Client:

SchemeRegistry schemeRegistry = new SchemeRegistry ();

schemeRegistry.register (new Scheme ("http",
    PlainSocketFactory.getSocketFactory (), 80));
schemeRegistry.register (new Scheme ("https",
    new CustomSSLSocketFactory (), 443));

ThreadSafeClientConnManager cm = new ThreadSafeClientConnManager (
    params, schemeRegistry);


return new DefaultHttpClient (cm, params);

CustomSSLSocketFactory:

public class CustomSSLSocketFactory extends org.apache.http.conn.ssl.SSLSocketFactory
{
private SSLSocketFactory FACTORY = HttpsURLConnection.getDefaultSSLSocketFactory ();

public CustomSSLSocketFactory ()
    {
    super(null);
    try
        {
        SSLContext context = SSLContext.getInstance ("TLS");
        TrustManager[] tm = new TrustManager[] { new FullX509TrustManager () };
        context.init (null, tm, new SecureRandom ());

        FACTORY = context.getSocketFactory ();
        }
    catch (Exception e)
        {
        e.printStackTrace();
        }
    }

public Socket createSocket() throws IOException
{
    return FACTORY.createSocket();
}

 // TODO: add other methods like createSocket() and getDefaultCipherSuites().
 // Hint: they all just make a call to member FACTORY 
}

FullX509TrustManager is a class that implements javax.net.ssl.X509TrustManager, yet none of the methods actually perform any work, get a sample here.

Good Luck!

This is what I am doing. It simply doesn't check the certificate anymore.

// always verify the host - dont check for certificate
final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
    public boolean verify(String hostname, SSLSession session) {
        return true;
    }
};

/**
 * Trust every server - dont check for any certificate
 */
private static void trustAllHosts() {
    // Create a trust manager that does not validate certificate chains
    TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return new java.security.cert.X509Certificate[] {};
        }

        public void checkClientTrusted(X509Certificate[] chain,
                String authType) throws CertificateException {
        }

        public void checkServerTrusted(X509Certificate[] chain,
                String authType) throws CertificateException {
        }
    } };

    // Install the all-trusting trust manager
    try {
        SSLContext sc = SSLContext.getInstance("TLS");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection
                .setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (Exception e) {
        e.printStackTrace();
    }
}

and

    HttpURLConnection http = null;

    if (url.getProtocol().toLowerCase().equals("https")) {
        trustAllHosts();
        HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
        https.setHostnameVerifier(DO_NOT_VERIFY);
        http = https;
    } else {
        http = (HttpURLConnection) url.openConnection();
    }

While trying to answer this question I found a better tutorial. With it you don't have to compromise the certificate check.
