Question

org.apache.commons.net.nntp crashing android

Answer 1

+1 A:

you haven't initialized the 'usenet' field, so you get a NullPointerException.

"NNTP usenet;" is equivalent to "NNTP usenet = null;".

How do i initialize it? i thought putting usenet.connect("ssl-eu.astraweb.com", 563); would do that?

it's going to be something like: NTTP usenet = new NTTP();the documentation for that class, which you can read on the web, suggests you probably want NNTPClient instead, but the principle's the same.you probably need to read an introductory book on Java, specifically the bits about the difference between variables and instances.

Answer 2

+1 A:

You need to initialize your variable usenet, by just using NTTP usenet its called declaring the variable. It just declares the variable to type NTTP and it has a reference to nothing, which is commonly defined as being null, hence the NullPointerException.

You might need to check out NTTPClient instead, so add this into your code

NTTPClient usenet = new NTTPClient();

That is initializing the variable usenet to a NTTPClient.
