soap - KSOAP 2 Android with HTTPS

Question

I am using KSOAP2 to manage SOAP in Android but it use https for the SOAP url and I am getting this error: javax.net.ssl.SSLException: Not trusted server certificate
A normal error because the certificate is untrusted, but anyone knows how to workaround with this error? I can not manage the certificate because is from a other company and I don't have access to change it.

Thanks

Checking again this problem, I've discovered a more clean solution for me. No KSOAP2 files modification needed.

In your project, link the ksoap2-android-assembly-3.0.0-jar, with no modifications.

Next, create a file named SSLConnection.java with this code:

package com.example.mypackage;

import android.util.Log;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

public class SSLConection {

    private static TrustManager[] trustManagers;

    public static class _FakeX509TrustManager implements javax.net.ssl.X509TrustManager {
        private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[]{};

        public void checkClientTrusted(X509Certificate[] arg0, String arg1)
                throws CertificateException {
        }

        public void checkServerTrusted(X509Certificate[] arg0, String arg1)
                throws CertificateException {
        }

        public X509Certificate[] getAcceptedIssuers() {
            return (_AcceptedIssuers);
        }
    }

    public static void allowAllSSL() {

        javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        });

        javax.net.ssl.SSLContext context;

        if (trustManagers == null) {
            trustManagers = new TrustManager[]{new _FakeX509TrustManager()};
        }

        try {
            context = javax.net.ssl.SSLContext.getInstance("TLS");
            context.init(null, trustManagers, new SecureRandom());
            javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());
        } catch (NoSuchAlgorithmException e) {
            Log.e("allowAllSSL", e.toString());
        } catch (KeyManagementException e) {
            Log.e("allowAllSSL", e.toString());
        }
    }
}

And just call to SSLConection.allowAllSSL(); before calling a server method via KSOAP2. It's all, works for me. All SSL certificates are accepted and I can use KSOAP2 with https protocol.
