HttpURLConnection setReadTimeout not working

Question

I am developing an application which requires downloading data from the server.
I use the following code, which works except that it got stuck sometimes at the midst of a file download.

try{ URL url = new URL( dlUrl ); con = (HttpURLConnection) url.openConnection(); con.setConnectTimeout(1000); // timeout 1 sec con.setReadTimeout(1000); // timeout 1 sec // get file length int lenghtOfFile = con.getContentLength(); is = url.openStream(); String dir = Environment.getExternalStorageDirectory() + "myvideos"; File file = new File( dir ); if( !file.exists() ){ if( file.mkdir()){ // directory succesfully created } } fos = new FileOutputStream(file + "/" + "video.mp4"); byte data[] = new byte[1024]; long total = 0; while( (count = is.read(data)) != -1 ){ total += count; publishProgress((int)((total*100)/lenghtOfFile)); fos.write(data, 0, count); } } catch (Exception e) { Log.e(TAG, "DOWNLOAD ERROR = " + e.toString() ); } finally{ // close streams }

The problem could be that the WIFI connection I am using is unstable, or something missing with my code.
Now I want to add a work around when the download stops, but unfortunately setReadTimeout seems to have no effect!
I tried the solutions suggested in Stackoverflow but none did the job for me.
Am I missing some kind of settings?
Any ideas why setReadTimeout has no effect?

Better late than never. I think I spotted the issue in your code. See my new answer below. Replace the call to url.openStream with con.getInputStream. — selbie

This is a new answer to year-old question, but I had a similar issue in my code that I have been able to resolve.

This line is the problem:

is = url.openStream();

The correct way to obtain the input stream is to simply get the input stream from the connection object not the url object.

is = con.getInputStream();

The former approach likely opens up another network conenction seperate from the connection object obtained by calling url.openConnection()

I figured all this out by evaluating this web blog page.

And for anyone else out there with a similar issue, it's also very important to call setReadTimout early - before calling the getInputStream or connect method on the connection object.

Perhaps a bit of a cop-out, but you might look into using a network library such as http://loopj.com/android-async-http/. I've found it helps alleviate a lot of tedious network debugging such as what you're describing.

The following is an example from the site:

AsyncHttpClient client = new AsyncHttpClient(); String[] allowedContentTypes = new String[] { "image/png", "image/jpeg" }; client.get("http://example.com/file.png", new BinaryHttpResponseHandler(allowedContentTypes) { @Override public void onSuccess(byte[] fileData) { // Do something with the file } });

Is it possible to download video and pdf files using this library?

HttpPost httpPostRequest = new HttpPost(URL); httpPostRequest.getParams().setParameter("http.socket.timeout", new Integer(600000));

I think it could work. But I am trying to solve HttpURLConnection.setReadTimeout(). Maybe as a last resort, I will try it.
