Java Push API

Here we list all API calls for the PubNub class in Java. This API is 100% compatible with all Java VMs including Android Phones, Google App Engine, Windows, Mac and Linux. This provides a complete Publish + Subscribe Push Notifications Framework in Java.

Initialize

	Pubnub pubnub = new Pubnub( 'publish_key', 'subscribe_key' );

Get your API Keys. You only need the Publish and Subscribe Keys. Ignore the Secret Key.

Publish

	// pubnub.publish( channel, message )
	// Create Pubnub Object
	Pubnub pubnub  = new Pubnub( "demo", "demo" );
	String channel = "java_test_channel";

	// Create JSON Message
	JSONObject message = new JSONObject();
	try { message.put( "some_val", "Hello World!" ); }
	catch (org.json.JSONException jsonError) {}

	// Publish Message
	JSONObject response = pubnub.publish( channel, message );

	// Print Response from PubNub JSONP REST Service
	System.out.println(response);
	System.out.println(response.optString("status"));
	System.out.println(response.optString("message"));

Subscribe

	// pubnub.subscribe( channel, callback )
	// Create Pubnub Object
	Pubnub pubnub  = new Pubnub( "demo", "demo" );
	String channel = "java_test_channel";

	// Callback Interface when a Message is Received
	class Receiver implements Callback {
	    public boolean execute(JSONObject message) {

	        // Print Received Message
	        System.out.println(message);

	        // Continue Listening?
	        return true;
	    }
	}

	// Create a new Message Receiver
	Receiver message_receiver = new Receiver();

	// Listen for Messages (Subscribe)
	pubnub.subscribe( channel, message_receiver );

History

	// pubnub.history( channel, limit )
	// Create Pubnub Object
	Pubnub pubnub  = new Pubnub( "demo", "demo" );
	String channel = "java_test_channel";
	int    limit   = 10;

	// Publish Message
	JSONArray response = pubnub.history( channel, limit );

	// Print Response from PubNub JSONP REST Service
	System.out.println(response);
	System.out.println(response.optJSONObject(0).optString("some_val"));
