How to listen for a custom URI

Question

I am working on an application which has its own URI prefix. (dchub:// in this case)

Searching all over and read a lot but I got a bit confused.

Is it possible

Answer 1

Don't use data.equals(null). That is bound to fail, you can't call methods on a null object, hence the NPE.

Why the emtpy code block? In my mind, this is a lot prettier:

if(data != null){
    // code here
}
