I would start here:

http://developer.android.com/reference/java/lang/StringBuilder.html

and

http://developer.android.com/reference/java/io/BufferedReader.html

The classes for java ( and androids java ) are pretty well documented, i always start there when im not sure how something is working.

Also, it seems a bit strage they way you have things here, but bascially BufferedReader will allow you to read from "in" one line at a time. You do not include here what the variable "in" refers to so it is hard to say where the actual data is coming from. But basically using StringBuilder, you are appending, one line at a time the String data from the BufferedReader into the StringBuilder which you can use to get the final string once the entire buffer has been read.

Also check this post out,

That will give you an idea of how to connect to your server and get the data from a particular script.
