Android : HttpClient POST : NullPointerException?

There could be too many reasons for that, and if you don't tell us which line is the number 60 we are not going to be able to help you. Anyway... so far I see a clear NullpointerException case: you first call login() and after that you initialize txtResult login(); layout = new LinearLayout(this); txtResult = new TextView(this) That of course will cause a NullPointerException because inside login() you are doing: txtResult. SetText(HttpHelper.

Request(response)) In that case txtResult have not been initialized, thus it's null Edit: Sigh... doing TextView txtResult = new TextView(this) outside any method will cause another NullPointerException That's because the use of this You better read little bit more about what it means, but let me give you a simple explanation: this is a keyword used to reference an instance of the object current object. Every initialization you do that is not inside a method will be called before the constructor is invoked (that's called lazy initialization), thus in that case the object has not been instantiated and this will be null What you have to do, and I thought you were going to get the idea is: layout = new LinearLayout(this); txtResult = new TextView(this); login().

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
