我在使用HttpURLConnection来进行Android的webservice api调用时，遇到了一个奇怪的问题。仅在Android 4.2.2版本中，我得到了以下异常。而在Android 4.0.3, 4.3和4.4及以上版本中均能正常运行。 以下是我用于服务api调用的代码。
HttpURLConnection mConn = (HttpURLConnection)mUrl.openConnection();
mConn.addRequestProperty("Connection", "close");
mConn.setConnectTimeout(CONNECTION_TIMEOUT);
mConn.setReadTimeout(SOCKET_TIMEOUT);
mConn.setUseCaches(true);
mConn.setRequestMethod("POST");
String param = Utils.appendQueryParams(null,this.stringparams);
mConn.setDoInput(true);
mConn.setDoOutput(true);
mConn.setFixedLengthStreamingMode(param.getBytes().length);
mConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
mConn.setRequestProperty("Accept", "application/json");
mConn.connect();
PrintWriter out = new PrintWriter(mConn.getOutputStream());
out.print(param);
out.close();
这里是异常信息（仅在Android SDK版本4.2.2中出现）
