我正在尝试从我正在创建的 Android 应用程序中连接到服务器上的网页，但由于某种原因，它似乎在一条线上失败了。
Java代码：
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 响应给了我一个 IllegalStateException - 无法访问应用程序密钥，我以前从未见过，也不知道如何修复它。它还提到了我的任何代码中都没有的 TimerTask.run() - 猜测它是 Android 自己的一些代码？
