如何处理HTTP响应InputStream？

Question

我的Android Mobile Java代码通过Http将交易记录推送到Cloud。我正在阅读Http响应，并根据响应采取进一步的措施。一切正常，但突然由于此行，应用程序开始挂起并停止工作：

responseInputStream =新的BufferedInputStream（httpURLConnection.getInputStream（））;

晚上又重新开始工作。所以我猜服务器上有一些问题。但是我想确保如果再次发生这种情况，我的应用程序应该不会挂起。我正在进行Http调用，并在try / catch块中读取响应，并处理所有异常，我还包括Exception，这样我就不会错过任何东西。但App仍然挂起。请任何人建议如何最好地处理阅读反应吗？

发布整个功能代码。

谢谢。
