Sample project using websockets on Android

Android Websocket Example

A sample application that keeps a permanent WebSocket connection in an Android bound Service.

When a message is received from the websocket, an event is sent via LocalBroadcastManager.

It handles network configuration changes using a receiver to stop/start the websocket depending on the network state.

The sheep in the current activity will start to bleat when a message is received from the websocket.

Try it

  • First, use NodeJS to launch the server:
$ npm install
$ node main
  • You can then access the websocket through:
http://localhost:3000/ws/
  • Then, modify the com.nilhcem.websockets.WebSocketsService.WS_URL constant to specify the server IP:
private static final String WS_URL = "ws://SERVER_IP:3000/ws/websocket";
  • Compile, deploy and run the application:
$ ./gradlew clean installDebug
  • Finally, send a POST request to http://SERVER_IP:3000/dispatchMessage, the websocket will send the message to all the connected clients. You can use the awesome rest-client tool to assist you in this task.

  • If the sheep bleats, that's a success (you can also see the received message in the device logs)
