File Directory Navigation with Android Nanohttpd lightweight server

Question

With the code below, i was able to create a mobile server on android phone with the Nanohttpd lightweight server. The code basically loop through the root directory of the h

Answer 1

i finally figure out how to do this after enough time of studying the NanoHTTPD Framework.The code below helps me to navigate within the directories in the host android device:

@Override
        public Response serve(String uri, Method method,
                Map header, Map parameters,
                Map files) {
            File rootDir = Environment.getExternalStorageDirectory();
            File[] filesList = null;
            String filepath = "";
            if (uri.trim().isEmpty()) {
                filesList = rootDir.listFiles();
            } else {
                filepath = uri.trim();
            }
            filesList = new File(filepath).listFiles();
            String answer = "";
            if (new File(filepath).isDirectory()) {
                for (File detailsOfFiles : filesList) {
                    answer += ""
                            + detailsOfFiles.getAbsolutePath() + "
";
                }
            } else {
            }
            answer += "" + "uri: " + uri + " \nfiles " + files
                    + " \nparameters " + parameters + " \nheader ";
            return new NanoHTTPD.Response(answer);
        }

the uri parameter in the Response Method contains browser url at that point in time: Example if url displaying on the address bar is: /192.168.43.1:8080/storage/sdcard1/Smadav_2012_Rev._9.0, then uri contains /storage/sdcard1/Smadav_2012_Rev._9.0. What i did is to just pass the uri as a filepath and of course, this is not the case for first connection when the uri is empty.
