Question

I have developed a HTTP GET Method that clearly works.

public class GetMethodEx {


public String getInternetData() throws Exception{

        new TrustAllManager();
        new TrustAllSSLSocketFactory();

        BufferedReader in = null;
        String data = null;


        try
        {
            HttpClient client = new DefaultHttpClient();
            URI website = new URI("https://server.com:8443/Timesheets/ping");
            HttpGet request = new HttpGet();
            request.setURI(website);
            HttpResponse response = client.execute(request);
            response.getStatusLine().getStatusCode();

            in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
            StringBuffer sb = new StringBuffer("");
            String l = "";
            String nl = System.getProperty("line.separator");
            while ((l = in.readLine()) !=null){
                sb.append(l + nl);
            }
            in.close();
            data = sb.toString();
            return data;        
        } finally{
            if (in != null){
                try{
                    in.close();
                    return data;
                }catch (Exception e){
                    e.printStackTrace();
                }
            }
        }
}

Here is a print screen of my emulator when retrieving a response from http://www.google.com

SCREEN SHOT OF GOOGLE.COM WORKING

The following code is my retrieval method to display it on screen.

public class Home extends Activity {

TextView httpStuff;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.httpexample);
    httpStuff = (TextView) findViewById(R.id.tvhttp);
   new LongOperation().execute("");

}

private class LongOperation extends AsyncTask<String, Void, String> {
  @Override

  protected String doInBackground(String... params) {

      GetMethodEx test = new GetMethodEx();      
      String returned = null;

    try {
        returned = test.getInternetData();

    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
        return returned;
  }      

  @Override
  protected void onPostExecute(String result) {    
     httpStuff.setText(result);       
  }

However, when I try it with my own server.

“https://server:port/xwtimesheets/ping“

I have the following screen

MY SERVER, NOT WORKING

Here is edited version of your GetMethodEx class. MySSLSocketFactory allows you to connect any server without checking their certificate. As you know it, this is not safe. I recommend you to add your servers’ certificate as trusted to your device.

By the way your servers certificate validity date is expired. Even if you add it as trusted, you may not connect to your server.

public class GetMethodEx {

public String getInternetData() throws Exception {


    BufferedReader in = null;
    String data = null;

    try {
        HttpClient client = new DefaultHttpClient();
        client.getConnectionManager().getSchemeRegistry().register(getMockedScheme());

        URI website = new URI("https://server.com:8443/XoW"); 
        HttpGet request = new HttpGet();
        request.setURI(website);
        HttpResponse response = client.execute(request);
        response.getStatusLine().getStatusCode();

        in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuffer sb = new StringBuffer("");
        String l = "";
        String nl = System.getProperty("line.separator");
        while ((l = in.readLine()) != null) {
            sb.append(l + nl);
        }
        in.close();
        data = sb.toString();
        return data;
    } finally {
        if (in != null) {
            try {
                in.close();
                return data;
            } catch (Exception e) {
                Log.e("GetMethodEx", e.getMessage());
            }
        }
    }
}

public Scheme getMockedScheme() throws Exception {
    MySSLSocketFactory mySSLSocketFactory = new MySSLSocketFactory();
    return new Scheme("https", mySSLSocketFactory, 443);
}

class MySSLSocketFactory extends SSLSocketFactory {
    javax.net.ssl.SSLSocketFactory socketFactory = null;

    public MySSLSocketFactory(KeyStore truststore) throws Exception {
        super(truststore);
        socketFactory = getSSLSocketFactory();
    }

    public MySSLSocketFactory() throws Exception {
        this(null);
    }

    @Override
    public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException,
            UnknownHostException {
        return socketFactory.createSocket(socket, host, port, autoClose);
    }

    @Override
    public Socket createSocket() throws IOException {
        return socketFactory.createSocket();
    }

    javax.net.ssl.SSLSocketFactory getSSLSocketFactory() throws Exception {
        SSLContext sslContext = SSLContext.getInstance("TLS");

        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);
        return sslContext.getSocketFactory();
    }
}
}
