In my application i have zipped web content. Web content has embedded video in it.
I show the wen content through Android web view. I serve my content through NanoHTTPD Server. I am on Android 4.2.2 and NanoHTTPD's latest version
My server supports partial content handling through range requests. This error comes in the initial call itself i.e. when accept-range response is sent from my server.
Video as ZipInputInflaterStream is sent in response from my server.
Whenever i try to view a video of large size i get this stack trace.

It seems the client socket in NanoHTTPD gets disconnected. Below is the code of NanoHTTPD which throws this error
private void sendAsFixedLength(OutputStream outputStream, int pending) throws IOException
{
if (requestMethod != Method.HEAD && data != null) {
int BUFFER_SIZE = 16 * 1024;
byte[] buff = new byte[BUFFER_SIZE];
while (pending > 0) {
int read = data.read(buff, 0, ((pending > BUFFER_SIZE) ? BUFFER_SIZE : pending));
if (read <= 0) {
break;
}
outputStream.write(buff, 0, read); //error thrown from here
pending -= read;
}
}
}
outputStream.write throws the above stack trace.
For large file like this after the exception happens the Android media player sends range requests. This works when i extract the file and send the content through FileInputStream.
Question is NanoHTTPD able to read ZipInputInflaterStream for a larger time ?.Even if it reads why client socket gets closed ?
Please note this problem only happens for large videos like for 19 MB. For smaller files like 11 MB it works.
cheers, Saurav
