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.
我试图根据服务器的响应显示消息,但不知何故每次都失败。当我通过提供静态值从不同的项目中单独运行来自java类的相同代码时,它运行正常,我能够获得响应代码。请参考代码并帮我纠正错误。

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.
我认为你是这个例子中过多复制和粘贴的受害者。我怀疑你得到了回复(否则你会遇到异常)。然后,您只是将它扔到System.out.println()。然后当你去设置responsecode时,readLine()返回null。
I tried to test it for myself, but I cannot use the API outside of India.
