Hi. I use Lyra in a Service and create Connection on a new thread. But when this line goes to execute

Thread thread = new Thread(new Runnable() {
        @Override
        public void run() {

 try {
         connection = Connections.create(options, config);
            } catch (IOException e) {
               e.printStackTrace();
            } catch (TimeoutException e) {
                e.printStackTrace();
           }
            getConsumerChannel();
        }
    });

    thread.setPriority(android.os.Process.THREAD_PRIORITY_BACKGROUND);
    thread.run();

it shows me this error. android.os.NetworkOnMainThreadException

What is the reason ?

It's not allowed to run networking code in the main app thread on android. To fix your example you need to call thread.start() instead of thread.run(). To undetstand the difference read javadocs of these methods or some article like this: http://javarevisited.blogspot.com/2012/03/difference-between-start-and-run-method.html.

What @atfire says. Connect in a separate thread.
