Please add a filtering for the required events and try. Sorry, I don’t know much about jeroMQ as I use CZMQ library, hence I don’t know the exact syntax for filtering in jeroMQ.

Subject: [zeromq-dev] Setting an Android Device as a Subscriber

Hello ZMQ,
Using Android Studio, and the jeromq-0.3.5.jar library, I am attempting to build a mobile application that will subscribe to a publisher that is dumping string messages.
Here is what my code looks like on the Subscriber side:

 Runnable runnable = new Runnable()
            public void run()
              ZMQ.Context context = ZMQ.context(1);
              ZMQ.Socket subscriber = context.socket(ZMQ.SUB);
              String testcase = subscriber.recvStr(0);
              TextView strDisplay = (TextView) findViewById(R.id.stringDisplay);
              Log.i("Output", "the testcase recieved something");
              Log.i("Output", "strDisplay was set");
The code hangs at:

String testcase = subscriber.recvStr(0);
I am not sure how to resolve this issue as I have tried various things. The IP Address and Port are correct, and the publisher is running. I can also provide the publisher side code if you need.
