java - how to create a server that send image from a request images from Glide? -

i'm using glide image loader client. , create own server java.

my server's code:

            file f = new file(imagelocation);             try{                 bi = imageio.read(f);             }catch (exception e){                 f = new file(imagelocation);                 bi = imageio.read(f);             }               respond = "http/1.1 200 ok\r\n";             respond += "date: " + localdatetime.now() + "\r\n";             respond += "content-type: image/png\r\n";             respond += "content-length: " + f.length() + "\r\n";             respond += "connection: keep-alive\r\n";             respond += "\r\n";             output.write((respond).getbytes());             output.flush();             imageio.write(bi,"jpg",output);             output.flush(); 

i tested browser , work fine, when call using glide android, no image displayed

the content-length may confuse glide, because you're lying it, original file length may not same re-encoded jpg output.

you're lying content-type because it's jpg, not png state it, think glide ignore that.

i think better send imagelocation's bytes output, content-length can predicted simply.

i still trying figure how exception glide if exist

as stated in google groups discussion, read https://github.com/bumptech/glide/wiki/debugging-and-error-handling , suggest add .listener(new requestlistener...) before .into(imageview) , log arguments see what's going on.
