  6. 6. What you deserve
  7. 7. Built with the Web Using HTML5, CSS3 and JavaScript with a number of APIs to build apps.
  8. 8. It’s open source
  9. 9. Some facts §  7 mobile operator & 4 hardware partners §  ZTE Open, Alcatel One Touch Fire, Geeksphone Keon, Geeksphone Peak, LG FireWeb… §  More to come: Huawei Y300, ZTE Open C, Alcatel One Touche Fire C & E & S… §  Aimed at emerging markets/low end market
  10. 10. A Firefox OS app? §  Creating a hosted or packaged app §  Using §  Vanilla HTML5 §  Librairies… §  Regular API §  Privileged API §  Certified API
  11. 11. 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" } } }
  12. 12. DEMO App Manager + Emberjs todomvc
  13. 13. Web APIs
  14. 14. 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
  15. 15. Ambient Light Sensor
  16. 16. 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); });
  17. 17. DEMO Boilerplate – Ambient Light Sensor
  18. 18. Battery Status
  19. 19. 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); }
  20. 20. DEMO Boilerplate – Battery status
  21. 21. Web APIs – Privileged •  Browser API •  Contacts API •  Device Storage API •  systemXHR •  TCP Socket API packaged
  22. 22. Browser
  23. 23. 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>
  24. 24. Browser addEventListener('mozbrowserloadstart', function(e) { //Do stuff }); /* Possible values: "mozbrowserloadstart“ "mozbrowserloadend" "mozbrowserlocationchange“ "mozbrowsertitlechange" "mozbrowsericonchange“ "mozbrowsersecuritychange" "mozbrowsercontextmenu“ "mozbrowsererror" "mozbrowserkeyevent“ "mozbrowsershowmodalprompt" "mozbrowseropenwindow“ "mozbrowserclose" */

  28. 28. Pick var activity = new MozActivity({ name: "pick", //Provide the data required //by the filter of the activity data: { type: "image/jpeg" } });
  29. 29. Pick activity.onsuccess = function () { var img = document.createElement("img"); if (this.result.blob.type.indexOf("image") != -1) { img.src = window.URL.createObjectURL(this.result.blob); } }; activity.onerror = function () { //error };
  30. 30. Dial var call = new MozActivity({ name: "dial", data: { number: "+46777888999" } });
  31. 31. Web Activity Received Handler "activities": { "pick": { "filters": { "type": ["image/jpeg", "image/png"] }, "disposition": "inline", "returnValue": true, "href": "/index.html#pick" } }
  32. 32. 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"); } } });
