Serve font/images with Nanohttpd from Android

I'm trying to host an Angular app with nanohttpd, so I put the files into a dist/ folder inside the assets folder of the android app. Now I want to serve the angular files but I keep getting this kind of errors in console (it only appears when trying to request fonts and images):

GET http://hostname/font.woff2 200 (OK)


This is the code that I use to serve the files:

public Response serve(IHTTPSession session)
String filepath = getFilepath(session.getUri()); // Get filepath depending on the requested url
String mimeType = getMimeType(filepath); // Get mimetype depending on the extension of the filepath (font/woff, font/woff2, font/ttf, image/x-icon, text/html, application/javascript)
String content;
byte buffer;
Response res;
InputStream is;
try
is = this.assetManager.open("dist/" + filepath);
int size = is.available();

buffer = new byte[size];
is.read(buffer);
is.close();

content = new String(buffer);
content = content.replace("old string", "new string");

if (typeText(mimeType)) // If mimeType is text/html or application/json
res = newFixedLengthResponse(content);
else // This is when I try to serve fonts or images
res = newFixedLengthResponse(Response.Status.OK, mimeType, is, size); // Not working


catch(IOException e)
res = newFixedLengthResponse("Error!");

return res;



I think that maybe the font files are getting compressed, or the size is not the real size of the InputStream. Also when loading the page, vendor.js takes a lot to download, and after that, it stops downloading the rest of the files.

I also get this error on the logcat:

Communication with the client broken, or an bug in the handler code

I fixed it like this:

public Response serve(IHTTPSession session)
String filepath = getFilepath(session.getUri()); // Get filepath depending on the requested url
String mimeType = getMimeType(filepath); // Get mimetype depending on the extension of the filepath (font/woff, font/woff2, font/ttf, image/x-icon, text/html, application/javascript)
String content;
byte buffer;
Response res;
InputStream is;
try
is = this.assetManager.open("dist/" + filepath);
if (!typeText(mimeType)) // If mimeType is font/<something> or image/<something>
return newFixedLengthResponse(Response.Status.OK, mimeType, is, -1);

int size = is.available();
buffer = new byte[size];
is.read(buffer);
is.close();
content = new String(buffer);
content = content.replace("old string", "new string");
catch(IOException e)
content = "Error!";

return newFixedLengthResponse(content);



I really don't know what happend, but it works really well this way. It seems to me that is.available() was not returning the right file size.

is.available()
