Android: Making Https Request

This method takes an HttpClient instance and returns a ready-for-https HttpClient instance.

 private HttpClient sslClient(HttpClient client) {    try {        X509TrustManager tm = new X509TrustManager() {             public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {            }            public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {            }            public X509Certificate[] getAcceptedIssuers() {                return null;            }        };        SSLContext ctx = SSLContext.getInstance("TLS");        ctx.init(null, new TrustManager[]{tm}, null);        SSLSocketFactory ssf = new MySSLSocketFactory(ctx);        ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);        ClientConnectionManager ccm = client.getConnectionManager();        SchemeRegistry sr = ccm.getSchemeRegistry();        sr.register(new Scheme("https", ssf, 443));        return new DefaultHttpClient(ccm, client.getParams());    } catch (Exception ex) {        return null;    }}

Because the Android org.apache.http.conn.ssl.SSLSocketFactory does not have the SSLSocketFactory(SSLContext) constructor, I have extended the class as follows.

 public class MySSLSocketFactory extends SSLSocketFactory {     SSLContext sslContext = SSLContext.getInstance("TLS");     public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {         super(truststore);         TrustManager tm = new X509TrustManager() {             public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {             }             public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {             }             public X509Certificate[] getAcceptedIssuers() {                 return null;             }         };         sslContext.init(null, new TrustManager[] { tm }, null);     }     public MySSLSocketFactory(SSLContext context) throws KeyManagementException, NoSuchAlgorithmException, KeyStoreException, UnrecoverableKeyException {        super(null);        sslContext = context;     }     @Override     public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {         return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);     }     @Override     public Socket createSocket() throws IOException {         return sslContext.getSocketFactory().createSocket();     }}

And some help here: Trusting all certificates using HttpClient over HTTPS

I had similar problem which is more like this question but the root cause was completely different from those mentioned in both questions.

I was using DefaultHttpClient as httpclient for requesting https://maps.googleapis.com like links. I was trying whole banch of proposed solutions but none worked for me. After some more hours trying to solve it found root cause: My device was connected to a guest WIFI which probably has some specific filtering rules which blocked relevant network parts. Switching to a different network solved my problem.
