- 6. 38 billion devices connected in 2020 ABI Research - 2013-05-09 - http://j.mp/38billion
- 11. Built with the Web Using HTML5, CSS3 and JavaScript with a number of APIs to build apps.
- 12. It’s open source
- 13. Some facts • Available in more than 24 countries • Primarly aimed at emerging & low end markets
- 14. Some of the devices
- 20. A Firefox OS app? § Creating a hosted or packaged app § Using § Vanilla HTML5 § Librairies… § Regular API § Privileged API § Certified API
- 21. HTML5 + manifest (JSON) = Firefox OS app { "version": “42", "name": ”My amazing app", "launch_path": "/index.html", "description": ”My super amazing app do super amazing things", "icons": { "16": "/images/logo16.png”,}, "developer": { "name": ”Frédéric Harper", "url": "http://outofcomfortzone.net", }, "default_locale": "en", "permissions": { "geolocation": { "description": ”Get the long/lat of the user" } } }
- 22. DEMO Firefox OS + App Manager + Emberjs todomvc
- 23. Web APIs
- 24. Web APIs – Regular • Alarm API • Ambient light sensor • Archive API • Battery Status API • Geolocation API • IndexedDB • Network Information API • Notifications API • Open WebApps • Proximity sensor • Push API • Screen Orientation • Vibration API • Web Activities • WebFM API • WebPayment packaged hosted
- 26. Ambient Light Sensor window.addEventListener("devicelight", function (event) { // The level of the ambient light in lux // The lux values for "dim" typically begin below 50, // and the values for "bright" begin above 10000 console.log(event.value); });
- 27. DEMO Boilerplate – Ambient Light Sensor
- 28. Battery Status
- 29. Battery Status var battery = navigator.battery; if (battery) { var batteryLevel = Math.round(battery.level * 100) + "%", charging = (battery.charging)? “yes" : "no", chargingTime = parseInt(battery.chargingTime / 60, 10, dischargingTime = parseInt(battery.dischargingTime / 60, 10); battery.addEventListener("levelchange", setStatus, false); battery.addEventListener("chargingchange", setStatus, false); battery.addEventListener("chargingtimechange", setStatus, false); }
- 30. Web APIs – Privileged • Browser API • Contacts API • Device Storage API • systemXHR • TCP Socket API packaged
- 31. Browser
- 32. Browser <div> <span id='location-bar'></span> <button onclick='go_button_clicked()'>Go</button> </div> <div id='load-status'></div> <div id='security-status'></div> <img id='favicon'> <div id='title'></div> <iframe mozbrowser src=‘yoursite.com' id='browser'></iframe>
- 33. Browser addEventListener('mozbrowserloadstart', function(e) { //Do stuff }); /* Possible values: "mozbrowserloadstart“ "mozbrowserloadend" "mozbrowserlocationchange“ "mozbrowsertitlechange" "mozbrowsericonchange“ "mozbrowsersecuritychange" "mozbrowsercontextmenu“ "mozbrowsererror" "mozbrowserkeyevent“ "mozbrowsershowmodalprompt" "mozbrowseropenwindow“ "mozbrowserclose" */

- 41. Don’t forget to handle it! navigator.mozSetMessageHandler('activity', function(activityRequest) { var option = activityRequest.source; if (activityRequest.source.name === "pick") { // Do something to handle the activity if (picture) { activityRequest.postResult(picture); } else { activityRequest.postError("Unable to provide a picture"); } } });
- 44. How to start
