Can I connect to WebSocket in an Android app?

Question

I have an Android app and I want to send text from an Android app to a web page using HTML5 WebSocket .

Is this possible, and if so, how?

Answer 1

A simple google search for 'android websockets' appeared this . He means the GitHub project called websocket-android-phonegap .

Answer 2

I know 2 libs for Android that support WebSockets from native applications

Autobahn supports RFC6455 (the final WS specification), integrates well with user interfaces and service applications, and supports RPC and PubSub via WebSockets.

Answer 3

Another alternative that may be considered is the Eneter Messaging Framework.
It is a cross-platform platform for interprocess communication, which is also available for Android and supports web ports. Technical summary can be found here:

Answer 4

Answer: Yes, you can send text from the application to the web page. WebSocket works by the very principle of server and client through TCP / IP. Just a shell created at the TCP / IP level and built a new data format that is defined by the IETF. Detailed information on the data format is available at: [ https://tools.ietf.org/html/rfc6455:51[1]

The server accepts a web socket connection if requested in the correct format. A client is a web application in which javascript objects are defined exclusively for this purpose in HTML5.

Easy to use APIs:

Programming client-side websites is very easy using new APIs and objects.

API (events) available to the developer: onopen, onclose, onmessage. All these functions must be defined by the java script developers.

onopen: the function is called when the server successfully accepts connections

onclose: function called when socket connection is closed

onmessage: the function is called when data is received from the server.

send: the function is not event-based, but should be started when the client has information to exchange with the server.
