Example implementation of Android ARP Cache

Example implementation of Android ARP Cache

Plugin

cordova-android-arp-cache: Get Android ARP Cache or Query ARP Cache against an IP Address or a MAC Address.

Setup

$ cordova create NetworkPeers
$ cd NetworkPeers
$ cordova platform add android --save
$ cordova plugin add cordova-arp-cache-fetch --save

Code

// www/js/index.js
var refreshCacheBeforeFetch = true;
var app = {
    // Application Constructor
    initialize: function() {
        document.addEventListener('deviceready', this.onDeviceReady.bind(this), false);
    },

    // deviceready Event Handler
    //
    // Bind any cordova events here. Common events are:
    // 'pause', 'resume', etc.
    onDeviceReady: function() {
        app.receivedEvent('deviceready');
    },

    // Update DOM on a Received Event - No such thing will happen :D
    receivedEvent: function(id) {
        app.runPlugin();
    },

    runPlugin: function() {
        if (refreshCacheBeforeFetch) {
