Android app crashes opening InputStream from an XML

Question

I made a SAX parser that accepts an InputStream as file to parse. If I use a local file it works, but if I try to get it from the internet it crashes when it opens the Input Stream.

There is the code:

    URL url = new URL(http://www.myDomain.com/xml/device.xml);
    URLConnection connection = url.openConnection();
    InputStream inStream = connection.getInputStream();

    ...

parser.parse(inStream, handler);

I have been trying it in several ways I have seen in other questions and it always crashes at InputStream inStream = connection.getInputStream(); or similar.

Thanks in advance.

Where can I find it? I started programming on Android yesterday and I amb a bit lost with the debugger view. Sorry. — Bartomeu Galmés, May 10 '14 at 14:51

More specifically to your question, this might be a [NetworkOnMainThreadException](http://stackoverflow.com/questions/6343166/android-os-networkonmainthreadexception?lq=1) — nhaarman, May 10 '14 at 14:57
Looking at the Stacktrace I have seen the exception you say. I will take a look at it. — Bartomeu Galmés, May 10 '14 at 15:00
I saw in that post that I forgot the Internet permissions. Thanks! — Bartomeu Galmés, May 10 '14 at 15:28

This might be NetworkOnMainThreadException you should not run costly operations like Network Connection on Main thread

Call that method in the following way

new Thread(new Runnable() {

        @Override
        public void run() {
            //Call your network connection method 
        }
    }).start();

I tried and it did not work, but after adding Internet permissions it did. Thanks! – Bartomeu Galmés May 10 '14 at 15:29
