I'd like to serve the files (.html and .css files, for example) of a local folder to recreate the usual behavior of a "real" local website.
Here are two examples of applications that work how I'd like mine to work: Tiny Web Server Free and kWS - Android Web Server.
I searched a lot with Google but I couldn't find anything...
I tried with NanoHttpd but it appears we can't set a root or home directory and we are only able to return some http code by returning a Response object with the serve() method. That's not what I want.
I'd like to be able to set a root directory, for example sdcard/www/, with a index.html that includes images from the sdcard/www/img/ subfolder...
Also, I found this answer, but this is not what I want. It consists in returning the content of an .html file in a Response object with the serve() method.
How could I do what I'd like to do?

I have been successfull in serving a folder of files via the following code... This is my Response method inside my Android Web Server class -->
public Response serve(IHTTPSession session) {
String uri=session.getUri();
String msg = "<html><body><h1>Hello server</h1>\n";
File [] arrayfile;
int i=0;
try{
session.parseBody(new HashMap<String, String>());
}catch (ResponseException | IOException r){
r.printStackTrace();
}
Map<String, String> parms = session.getParms();
if (parms.get("username") == null) {
msg += "<form action='?' method='get'>\n <p>Your name: <input type='text' name='username'></p>\n" + "</form>\n";
} else {
msg += "<p>Hello, " + parms.get("username") + "!</p>";
}
msg += "<br><br><a href='/Open_rap'>Open Image of Lionel Messi</a><br><br>";

As you can see, the part where
uri.contains(.)
this part of code is where I implement the folder using a root file object and
file input stream
My files are kept inside the internal storage of my android device /www/files
Ping me if you have any issue.

You can use google/webview-local-server

I am using nanohttpd to serve files here is my working code that i used
@Override
public Response serve(IHTTPSession session) {
String msg = "<html><body><h1>Hello server</h1></body></html>\n";
String msgUnauthorized = "<html><body><h1>Unauthorized</h1></body></html>\n";
Method method = session.getMethod();
String uri = session.getUri();
Map<String, String> files = new HashMap<>();
String Endpoint = session.getUri();
if (Endpoint.equals("/")) {
String answer = "";
try {
// Open file from SD Card
File root = Environment.getExternalStorageDirectory().getAbsoluteFile();
FileReader index = new FileReader(root +
"/www/openrap/index.html");
BufferedReader reader = new BufferedReader(index);
String line = "";
while ((line = reader.readLine()) != null) {
answer += line;
}
reader.close();
} catch (IOException ioe) {
Log.w("Httpd", ioe.toString());
}
return newFixedLengthResponse(answer);
}
