App Socket

The App Socket library allows for the creation of sockets between Android applications. This allows for the creation of Client-Server style applications among Android applications. Once the socket are connected, applications can share data with one another over these sockets.

How to Use

Setup

Include the below dependencies in your build.gradle project.

buildscript {
    repositories {
        jcenter()
        maven { url "https://newtronlabs.jfrog.io/artifactory/libs-release-local"
            metadataSources {
                artifact()
            }
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'
        classpath 'com.newtronlabs.android:plugin:4.0.5'
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://newtronlabs.jfrog.io/artifactory/libs-release-local"
            metadataSources {
                artifact()
            }
        }
    }
}

subprojects {
    apply plugin: 'com.newtronlabs.android'
}

In the build.gradle for your app.

dependencies {
    compileOnly 'com.newtronlabs.appsocket:appsocket:4.0.0'
}

App Socket - Server

From the server application create a server socket and listen for clients.

// Create a server socket on port 2222
IAppServerSocket serverSocket = new AppServerSocket(2222)

// Wait for client to connect
IAppSocket clientSocket = serverSocket.accept();

// Get stream for writing to client.
OutputStream os = clientSocket.getOutputStream();

// Get stream for reading from the client
InputStram is = clientSocket.getInputStream();

App Socket - Client

In order for an Android application to communicate with server app do the following:

// This is the application id of the application that has the server socket.
String serverAppId = "com.newtronlabs.appsockserver";

// This is the port on which that app is listening on.
int port = 2222;

// Create the socket.
IAppSocket socket = new AppSocket();

// Connect to remote application.
socket.connect(context, serverAppId, port);

// Get stream for writing to the server.
OutputStream os = clientSocket.getOutputStream();

// Get stream for reading from the server
InputStram is = clientSocket.getInputStream();

A set of more complex exmaples can be found in this repo's samples folders: AsServer and AsClient.
