    • Firefox OS Lengyel Zsolt zsolt.lengyel.it@gmail.com
    • Bringing the Open Web to Mobile Devices OS
    • Bringing The Boot to Gecko project was launched to enable the Open Web as a platform for mobile devices. We’re making innovation possible by driving the development of new Web standards.
    • Operators and developers write apps and services for one platform and then rewrite them for others. Users who want to buy phones, e-readers and game consoles from different manufacturers often need to repurchase apps for each device.
    • Opportunities for Developers
    • Using HTML5 and the new Mozillaproposed standard APIs, developers everywhere will be able to create amazing experiences and apps. Developers will no longer need to learn and develop against platform-specific native APIs.
    • Customization for OEMs & Operators
    • OEMs and operators will be able to provide content and services across their entire device portfolio, regardless of OS. And they will be able to customize user experiences, manage app distribution and retain customer attention, loyalty and billing relationships.
    • Consumer Freedom
    • Consumers who use devices based on the Open Web platform will be able to easily access and download their own content regardless of which OS they use.
    • New Web Standards
    • Firefox OS produces an implementation of these new Web standards to free mobile platforms from the encumbrances of the rules and restrictions of existing proprietary platforms.
    • Components
    • GAI A APPS GECKO GONK
    • GONK
    • Lower level operating system, consisting of a Linux kernel and HAL (Hardware Abstraction Layer). Possibility to expose anything from the hardware to Gecko.
    • GECKO
    • The application runtime. The rendering engine in Firefox for HTML5, CSS & JavaScript. Implements a number of APIs.
    • GAIA
    • The user interface. Built entirely by HTML5 & Open Web APIs.
    • Web APIs
    • The Boot to Gecko project is based entirely on open standards and the source code is open and accessible to all. Where open standards are missing, we're working with standards bodies and other vendors to create them.
    • WEBTELEPHONY
    • // Telephony object var tel = navigator.mozTelephony; // Check if the phone is muted (read/write property) console.log(tel.muted); // Check if the speaker is enabled (read/write property) console.log(tel.speakerEnabled);
    • // Place a call var cal = tel.dial(“123456789”);
    • // Events for that call call.onstatechange = function (event) { /* Possible values for state: "dialing", "ringing", "busy", "connecting", "connected", "disconnecting", "disconnected", "incoming" */ console.log(event.state); }; // Above options as direct events call.onconnected = function () { // Call was connected }; call.ondisconnected = function () { // Call was disconnected };
    • // Receiving a call tel.onincoming = function (event) { var incomingCall = event.call; // Get the number of the incoming call console.log(incomingCall.number); // Answer the call incomingCall.answer(); }; // Disconnect a call call.hangUp(); // Iterating over calls, and taking action depending on their changed status tel.oncallschanged = function (event) { tel.calls.forEach(function (call) { // Log the state of each call console.log(call.state); }); };
    • WEBSMS
    • // SMS object var sms = navigator.mozSMS; // Send a message sms.send("123456789", "Hello world!");
    • // Recieve a message sms.onreceived = function (event) { // Read message console.log(event.message); };
    • BATTERY STATUS API
    • var battery = navigator.mozBattery if (battery) { var batteryLevel = Math.round(battery.level * 100) + "%", charging = (battery.charging)? "" : "not ", chargingTime = parseInt(battery.chargingTime / 60, 10, dischargingTime = parseInt(battery.dischargingTime / 60, 10); // Set events battery.addEventListener("levelchange", setStatus, false); battery.addEventListener("chargingchange", setStatus, false); battery.addEventListener("chargingtimechange", setStatus, false); battery.addEventListener("dischargingtimechange", setStatus, false); }
    • VIBRATION API
    • // Vibrate for one second navigator.mozVibrate(1000); // Vibration pattern [vibrationTime, pause,…] navigator.mozVibrate([200, 100, 200, 100]); // Vibrate for 5 seconds navigator.mozVibrate(5000); // Turn off vibration navigator.mozVibrate(0);
    • CONTACTS API
    • var contact = new mozContact(); contact.init({name: "Tom"}); var request = navigator.mozContacts.save(contact); request.onsuccess = function() { console.log("Success"); }; request.onerror = function() { console.log("Error") };
    • SETTINGS API
    • var settings = window.navigator.mozSettings; settings.getLock().set({"background": "pretty.png"});
    • DEVICE STORAGE API
    • var storage = navigator.getDeviceStorage("videos"), cursor = storage.enumerate(); cursor.onerror = function() { console.error("Error in DeviceStorage.enumerate()", cursor.error.name); }; cursor.onsuccess = function() { if (!cursor.result) return; var file = cursor.result; // If this isn't a video, skip it if (file.type.substring(0, 6) !== "video/") { cursor.continue(); return; } // If it isn't playable, skip it var testplayer = document.createElement("video"); if (!testplayer.canPlayType(file.type)) { cursor.continue(); return; } }
    • SCREEN ORIENTATION API
    • // Portrait mode: screen.mozLockOrientation("portrait"); /* Possible values: "landscape" "portrait" "landscape-primary" "landscape-secondary" "portrait-primary" "portrait-secondary" */
    • NETWORK INFORMATION API
    • var connection = window.navigator.mozConnection, online = connection.bandwidth > 0, metered = connectrion.metered;
    • KEYBOARD/IME API
    • var keyboard = window.navigator.mozKeyboard; keyboard.sendKey(0, keyCode);
    • Web Apps from Mozilla
    • Vibration API, Screen Orientation, Geolocation API, Mouse Lock API, Open WebApps, Network Information API, Battery Status API, Alarm API, Push Notifications API, WebFM API / FMRadio, WebPayment, IndexedDB, Ambient light sensor, Proximity sensor, Notification Security Levels HOSTED Device Storage API Browser API TCP Socket API Contacts API systemXHR WebTelephony, WebSMS, Idle API, Settings API, Power Management API, Mobile Connection API, WiFi Information API, WebBluetooth, Permissions API, Network Stats API, Camera API, Time/Clock API, Attention screen, Voicemail PRIVILEGED CERTIFIED
    • Writing Apps, Mozilla Marketplace
    • Web apps are apps built using standard Web technologies. They work in any modern Web browser, and can be developed using your favorite tools. The Open Web apps project proposes some small additions to existing sites to turn them into apps that run in a rich, fun, and powerful computing environment. These apps run on desktop browsers and mobile devices, and are easier for a user to discover and launch than Web sites.
    • Steps to Take
    • 1. Develop Web App using HTML5, CSS, & Javascript 2. Create an app manifest file 3. Publish/install the app
    • Develop Web App using HTML5, CSS & JavaScript
    • Reuse any existing web site/app or develop from scratch with open web standards. Utilize HTML5 features such as localStorage, offline manifest, IndexedDB and access Web APIs for more options. Responsive web design for adapting to varying resolutions and screen orientation.
    • Create an app manifest file
    • Create a file with a .webapp extension
    • { "version": "1.0", "name": "MozillaBall", "description": "Exciting Open Web development action!", "icons": { "16": "/img/icon-16.png", "48": "/img/icon-48.png", "128": "/img/icon-128.png" }, "developer": { "name": "Mozilla Labs", "url": "http://mozillalabs.com" }, "installs_allowed_from": ["*"], "appcache_path": "/cache.manifest", "locales": { "es": { "description": "¡Acción abierta emocionante del desarrollo del Web!", "developer": { "url": "http://es.mozillalabs.com/" } }, "it": { "description": "Azione aperta emozionante di sviluppo di fotoricettore!", "developer": { "url": "http://it.mozillalabs.com/" } } }, "default_locale": "en" }
    • MANIFEST CHECKER
    • Publish/install the app
    • Mozilla Marketplace
    • Installing/hosting the app
    • var request = navigator.mozApps.install( "http://mozillalabs.com/MozillaBall.webapp", { user_id: "some_user" } ); request.onsuccess = function() { // Success! Notification, launch page etc } request.onerror = function() { // Failed. this.error.name has details }
