Android connect to website using HttpUrlConnection fails

Question

I'm trying to connect to a webpage on my server from within an Android app I'm creating, but it seems to be failing on one line for some reason.

Java code:

URL url = new URL("http://redsquirrelsoftware.co.uk/android/assignments/androidlogin.php");
HttpURLConnection hConnection = (HttpURLConnection)url.openConnection();
HttpURLConnection.setFollowRedirects(true);

hConnection.setDoOutput(true);
hConnection.setRequestMethod("POST");   

// ERROR OCCURS ON NEXT LINE
PrintStream ps = new PrintStream(hConnection.getOutputStream());
ps.print("email=" + LoginActivity.email + "&" + "pword=" + LoginActivity.password);
ps.close();
hConnection.connect();

LogCat response is giving me an IllegalStateException - Unable to access the application key, which I have never seen before and don't know how to go about fixing it. It also mentions TimerTask.run(), which I don't have in any of my code - guessing it's some of Android's own code?

Any suggestions on how to go about fixing it? Cheers

I think that the relevant line in the log is:

01-08 21:28:57.990: E/InputDispatcher(165): channel '41621cb0 uk.co.redsquirrelsoftware.assignmenttracker/uk.co.redsquirrelsoftware.assignmenttracker.LoginActivity (server)' ~ Channel is unrecoverably broken and will be disposed!
