Dear friends,

i implement all service’s by using retrofit library for this issue.
how ever i have not any problem.

test it ->

public class ServiceGeneratorCollege {

    public static String PREF_COOKIES = "pref_cookies";

    private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

    private static Retrofit.Builder builder;

    public static <S> S createService(Class<S> serviceClass) {
        return createService(serviceClass, null);
    }

    public static <S> S createService(Class<S> serviceClass, final HashMap<String, String> headers) {

        builder = new Retrofit.Builder()
                .baseUrl("your service address")
                .addConverterFactory(GsonConverterFactory.create());

        httpClient.sslSocketFactory(getSSLSocketFactory());
        httpClient.hostnameVerifier(new HostnameVerifier() {

            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        });

        OkHttpClient client = httpClient.build();
        Retrofit retrofit = builder.client(client).build();
        return retrofit.create(serviceClass);
    }

    private static SSLSocketFactory getSSLSocketFactory() {
        try {
            // Create a trust manager that does not validate certificate chains
            final TrustManager[] trustAllCerts = new TrustManager[]{
                    new X509TrustManager() {
                        @Override
                        public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                        }

                        @Override
                        public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                        }

                        @Override
                        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                            return new java.security.cert.X509Certificate[]{};
                        }
                    }
            };

            // Install the all-trusting trust manager
            final SSLContext sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
            // Create an ssl socket factory with our all-trusting manager
            final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

            return sslSocketFactory;
        } catch (KeyManagementException | NoSuchAlgorithmException e) {
            return null;
        }

    }
}
