HTTPS Server on Android Device Using NanoHttpd

Question

I am trying to run an HTTPS Server on an Android device using NanoHttpd (my final goal is to run WSS server on Android). I successfully ran HTTP Server and Websocket using NanoH

Answer 1

After Hours of toil, I've got it!

Here is MY (working) code:

// I placed this block right below my class declaration so it runs
// as soon as the class is defined. (this is for localhost testing ONLY!!!!)    
static {
    //for localhost testing only
    javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
    new javax.net.ssl.HostnameVerifier(){

        public boolean verify(String hostname,
                javax.net.ssl.SSLSession sslSession) {
            if (hostname.equals("localhost")) {
                return true;
            }
            return false;
        }
    });
}

// then in an init function, I set it all up here
this.secureAppServer = new NanoHTTPD(9043);
File f =new File("src/main/resources/key001.jks");
System.setProperty("javax.net.ssl.trustStore", f.getAbsolutePath());
this.secureAppServer.setServerSocketFactory(new SecureServerSocketFactory(NanoHTTPD.makeSSLSocketFactory("/" +f.getName(), "myawesomepassword".toCharArray()), null));

this.secureAppServer.start();

Here is the actual NanoHttpd Test case which illustrates exactly how its done Nano style.
