Apps Http Connection Error - Already Connected ? No it isn't!

[ac4android]

Hi, I am re-using some http connection code, they worked well in my AsyncTask, tested and true.

This time, I called the method inside my Handler, like this:

  final Handler handler = new Handler();
  handler.post(new Runnable() {
  @Override
  public void run() {
  //TODO
  String slat = String.valueOf(dd);
  sysmsgview.setText(slat);
  latitudeview.setText(latitude);
  longitudeview.setText(longitude);
  accuracyview.setText(accuracy);
  if (running) {
  dd++;
  // hardvoded for testing
  latitude = "84.012345";
  longitude = "-114.2345";
  if (latitude != null && longitude != null){
  Toast.makeText(getApplicationContext(),
  "Uploading "+ dd + " Latitude:Longitude ->" + latitude +":" + longitude,
Toast.LENGTH_LONG).show();


  new UploadActivity(getApplicationContext()).execute( latitude, longitude);
  }
  }
  handler.postDelayed(this, 10000);
  }
  });
  }

It threw a java.lang.illegalStateException: Already connected.
How could it be already connected?????? Doesn't make sense.

  HttpURLConnection conn = (HttpURLConnection) url.openConnection();
  if (!(conn instanceof HttpURLConnection)) {
  throw new IOException("ERROR: urlConn not instance of HttpUrlConnection.");
  }
  conn.setRequestMethod("POST");
  conn.connect();
  conn.setDoOutput(true);
  OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream()); // <-- THROWS EXCEPTION HERE!
  writer.write(data);
  writer.flush();
  BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
  StringBuilder stringBuilder = new StringBuilder();
  String line = null;
  // Read Server Response
  while ((line = reader.readLine()) != null) {
  stringBuilder.append(line);
  break;
  }
  reader.close();
  return stringBuilder.toString();
  } catch (Exception e) {
  return new String("Exception: " + e.getMessage());
  }

You could try calling disconnect() before openConnection()

Hi and thx again.

Yeah, That's what I am going to do tomorrow, but Java is supposed to close the connection when it hits reader.close(), it never got to that point.

Still curious how the connection was in an "open" state because nothing in the code opens the connection prior to that point, unless the handler-thread and the AsyncTask were still alive after completing the last AsyncTask task.

I thought after an AsyncTask completes it job, it dies and releases memory, and not hang around like a background thread
