我试图显示基于从服务器，但不知何故没有它每次的响应消息。当我通过提供其运行正常静态值运行从不同的项目java类单独在同一code和我能够得到的回应code。请参照code，帮我纠正错误。

我觉得你的太多副本的受害者，从的的例子的。我怀疑你得到的回应（否则你会遇到一个例外）。然后，您只是throwing它带到一个的System.out.println（）。然后，当你去设置响应code 的的readLine（）返回null。
我试图测试它为我自己，但我不能使用API印度以外。
I am trying to display the message based on the response from the server but somehow its failing everytime. When i am running the same code from java class seperately from different project by providing static values it is running properly and i am able to get the response code. Please refer the code and help me rectify the error.

解决方案
I think you are a victim of too much copy and paste from the example. I suspect you are getting a response (otherwise you would encounter an exception). You are then are just throwing it away to a System.out.println(). Then when you go to set responsecode readLine() returns null.
I tried to test it for myself, but I cannot use the API outside of India.
