我正在努力解决一个奇怪的问题，同时在Android中使用 HttpURLConnection 进行webservice api调用。我正在低于例外仅适用于Android 4.2.2版。它在Android 4.0.3,4.3和4.4及更高版本中运行良好。 我使用下面的代码进行服务api调用。
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();
以下是例外（仅限Android SDK版本4.2.2）
