loadJSONArray immediately failing on Android build
Hi all! I am working on a little project which makes a request for a JSON array from an external server based on a lat/long pairing. The app compiles ok without errors, and runs ok on the device, but when I tap to make the request it immediately crashes.
I made a change to push the lat/long to the screen and that is functioning ok, and I am casting the lat/long to strings to construct the URL ok, but I am now just a bit stuck why it should just fall over when just trying to push the loadJSONArray request to a JSONArray var.
Any thoughts?

what happens if you have your .json in your app (or with an uri towards the sd card)??? if everything works that could mean that you must create a thread or an asyncTask for loading on line.
Hey @akenaton it seems that directly parsing the JSON works ok when I include it as a string. After looking around at asyncTask I understand that it would be more ideal for short processes, so will look at the thread route. Thanks for replying!

right, if download is a long process threading is better...
Will try and get round to making that change today, and will update the thread when it works
Thanks @akenaton for pointing me towards thread() - that did the trick and it's loading / parsing the json correctly now
