HttpURLConnection setConnectTimeout() has no effect

Question

I\'m connecting to a simple RSS feed using HTTPUrlConnection. It works perfectly. I\'d like to add a timeout to the connection since I don\'t want my app hanging in the even

I had a similar problem - because the HttpUrlConnection won't time out mid-download. For example, if you turn off wifi when download is going, mine continued to say it is downloading, stuck at the same percentage.

I found a solution, using a TimerTask, connected to a AsyncTask named DownloaderTask. Try:

class Timeout extends TimerTask {
    private DownloaderTask _task;

    public Timeout(DownloaderTask task) {
        _task = task;
    }

    @Override
    public void run() {
        Log.w(TAG,"Timed out while downloading.");
        _task.cancel(false);
    }
};

Then in the actual download loop set a timer for timeout-error:

                    _outFile.createNewFile();
                    FileOutputStream file = new FileOutputStream(_outFile);
                    out = new BufferedOutputStream(file);
                    byte[] data = new byte[1024];
                    int count;
                    _timer = new Timer();
                    // Read in chunks, much more efficient than byte by byte, lower cpu usage.
                    while((count = in.read(data, 0, 1024)) != -1 && !isCancelled()) { 
                        out.write(data,0,count);
                        downloaded+=count;
                        publishProgress((int) ((downloaded/ (float)contentLength)*100));
                        _timer.cancel();
                        _timer = new Timer();
                        _timer.schedule(new Timeout(this), 1000*20);
                    }
                    _timer.cancel();
                    out.flush();

If it times out, and won't download even 1K in 20 seconds, it cancels instead of appearing to be forever downloading.
