You can use the resulting InputStream to receive data from the client, and use the corresponding OutputStream to send data back. Val outputStream = socket.getOutputStream() Since the communication is bi-directional, you can obtain two different streams from the socket: val inputStream = socket.getInputStream() The returned Socket object represents the communication channel between the server and the connected client. This call will block until the next client connects, so donвЂ™t call this method on UI thread: val socket = serverSocket.accept() To make ServerSocket accept connection requests from clients, call its accept() method. Since ports are involved, you can already guess that this server will become an endpoint on a TCP/IP network.

To instantiate ServerSocket, youвЂ™ll need to specify a specific port that the server will be listening on: val serverSocket = ServerSocket(50000) This class basically realizes serverвЂ™s functionality and abstracts out most of the underlying complexity from you. LetвЂ™s review the main building blocks of an embedded web server in Android.ДЇirst, youвЂ™ll need to use ServerSocket class.

In this post IвЂ™ll explain the basics of web servers in Android applications and provide a reference implementation that you can use to bootstrap your own efforts. Embedding web servers in Android apps is a niche use case, but, after seeing three different clients using this approach, IвЂ™m pretty sure itвЂ™s not exceptionally rare either.

This will allow your application to accept network connections from external (or internal) clients and establish a bi-directional communication with them. It might sound odd, but you can turn your Android application into a full-blown web server.
