2013-02-20 version 0.10beta released

I've changed a coupe of things in this release.

• Hubs is now implemented. Checkout my implementation and say what you think about it. Calling functions on server from client, and calling functions on client from server is supported. NOTE! State is not implemented yet.
• I've included a new sample, HubDemo, in the repo. It shows how you can implement hubs.
• I have also set up a SignalR server on Appharbor so HubDemo can talk to it. You'll find it here.

2013-02-20 version 0.9beta released

Version 0.9beta uses the SignalR-protocol version 1.2 which is used in the 1.0 release of SignalR. It has also (beta)support for groups.

Description

SignalA is a SignalR-client for Android. It's implemented as a Android-library. At this moment is long polling the only implemented transport. Long polling is a separate library. Http-requests in the Long polling library is using basic-http-client.

Add SignalA to your project

SignalA is published on Maven Central as a ARR. If you're using Android Studio/Gradle all you have to do is add it on your gradle build:

dependencies {
    compile 'com.github.erizet.signala:signala-longpolling:0.20'
}

How to use?

Add the following code to your activity.

  String url = "http://<address to your SignalR-server>";
  con = new com.zsoft.signala.Connection(url, this, new LongPollingTransport()) {

		@Override
		public void OnError(Exception exception) {
            Toast.makeText(DemoActivity.this, "On error: " + exception.getMessage(), Toast.LENGTH_LONG).show();
		}

		@Override
		public void OnMessage(String message) {
            Toast.makeText(DemoActivity.this, "Message: " + message, Toast.LENGTH_LONG).show();
		}

		@Override
		public void OnStateChanged(StateBase oldState, StateBase newState) {
		}
	};

To start and stop the SignalA connection use code similar to the following.

public void startSignalA()
{
	if(con!=null)
		con.Start();
}

public void stopSignalA()
{
	if(con!=null)
		con.Stop();
}

That's it!

For a complete sample see the Demo-project.

Limitations

Hubs don't support State yet.
