  11. 11. WebAPIs
  12. 12. Segurança
  13. 13. Aplicações Conteúdo Web Apps Web Privilegiadas Conteúdo Web comum Mais acesso, mais responsabilidades App Web Instalada App Web Certificada Uma App Web comum Apps críticas aos aparelho (hardware)
  14. 14. Permissões https://developer.mozilla.org/en-US/Apps/Developing/App_permissions

 "contacts": {
 "description": "Required for autocompletion in the share screen",
 "access": "readcreate"
 },

 }
 }
  16. 16. WEB APIs
  17. 17. WEB APIS (PARA TODOS) Vibration API (W3C) Web Activities Screen Orientation Push Notifications API Geolocation API WebFM API Mouse Lock API (W3C) WebPayment Open WebApps IndexedDB (W3C) Network Information API (W3C) Ambient light sensor Battery Status API (W3C) Proximity sensor Alarm API Notification
  18. 18. API STATUS DA BATERIA
  19. 19. var battery = navigator.battery;
 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); }
  20. 20. NOTIFICAÇÃO
  21. 21. var notification = navigator.mozNotification;
 notification.createNotification(
 "See this", 
 "This is a notification", 
 iconURL
 );
  22. 22. API ORIENTAÇÃO DE TELA
  23. 23. // Portrait mode:
 screen.mozLockOrientation("portrait");
 
 /* 
 Possible values:
 "landscape" 
 "portrait"
 "landscape-primary"
 "landscape-secondary"
 "portrait-primary"
 "portrait-secondary"
 */
  24. 24. VIBRATION API
  25. 25. // Vibrate for one second
 navigator.vibrate(1000);
 
 // Vibration pattern [vibrationTime, pause,…]
 navigator.vibrate([200, 100, 200, 100]);
 
 // Vibrate for 5 seconds
 navigator.vibrate(5000);
 
 // Turn off vibration
 navigator.vibrate(0);
  26. 26. VISIBILIDADE DA PÁGINA
  27. 27. document.addEventListener("visibilitychange", function (event) {
 if (document.hidden) { console.log(event."App is hidden"); } else { console.log(event."App has focus"); }
 });
  28. 28. NETWORK INFO API
  29. 29. var connection = window.navigator.mozConnection,
 online = connection.bandwidth > 0,
 metered = connection.metered;

  30. 30. PROXIMIDADE
  31. 31. window.addEventListener("deviceproximity", function (event) {
 // Current device proximity, in centimeters
 console.log(event.value);
 
 // The maximum sensing distance the sensor is 
 // able to report, in centimeters
 console.log(event.max);
 
 // The minimum sensing distance the sensor is 
 // able to report, in centimeters
 console.log(event.min);
 });
  32. 32. AMBIENT LIGHT EVENT
  33. 33. window.addEventListener("devicelight", function (event) {
 // The level of the ambient light in lux
 console.log(event.value);
 });
  34. 34. window.addEventListener("devicelight", function (event) {
 // The lux values for "dim" typically begin below 50,
 // and the values for "bright" begin above 10000
 console.log(event.value);
 });
  35. 35. WEB APIS (APPS PRIVILEGIADAS) Device Storage API Browser API TCP Socket API Contacts API systemXHR
  36. 36. DEVICE STORAGE
  37. 37. var deviceStorage = navigator.getDeviceStorage("videos");
  38. 38. // "external", "shared", or "default".
 deviceStorage.type;
 
 // Add a file - returns DOMRequest with file name
 deviceStorage.add(blob);
 
 // Same as .add, with provided name
 deviceStorage.addNamed(blob, name);
 
 // Returns DOMRequest/non-editable File object
 deviceStorage.get(name);
 
 // Returns editable FileHandle object
 deviceStorage.getEditable(name);
 
 // Returns DOMRequest with success or failure
 deviceStorage.delete(name);
 
 // Enumerates files
 deviceStorage.enumerate([directory]);
 
 // Enumerates files as FileHandles
 deviceStorage.enumerateEditable([directory]);
  39. 39. 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;
 }
 };
  40. 40. API DE CONTATOS
  41. 41. var addContact = document.querySelector("#add-contact");
 if (addContact) { 
 addContact.onclick = function () {
 var newContact = new MozActivity({
 name: "new", // Possibly add-contact in future versions
 data: {
 type: "webcontacts/contact",
 params: { // Will possibly move to be direct properties under "data"
 giveName: "Fabio",
 familyName: "Magnoni",
 tel: "+5519988013586",
 email: "fabio@mozilla.com",
 address: "Campinas",
 note: “Se tiver cerveja envolvida, pode entrar em contato :)”,
 company: "Mozilla"
 }
 }
 });
 }
 }
  42. 42. Apps Certificadas = DO SO
  43. 43. Dialer ! Contacts ! Settings ! SMS ! Web browser ! Gallery ! Video Player ! Music Player ! E-mail (POP, IMAP) ! Calendar Alarm Clock ! Camera ! Notes ! First Run Experience ! Notifications ! Home Screen ! Mozilla Marketplace ! System Updater ! Localization Support
  44. 44. WEB ACTIVITIES
  45. 45. var activity = new MozActivity({
 name: "view", 
 data: {
 type: "image/png", 
 url: ... 
 }
 });
 activity.onsuccess = function () {
 console.log("Showing the image!");
 }; 
 activity.onerror = function () {
 console.log("Can't view the image!");
 };
  46. 46. {
 "activities": {
 "share": {
 "filters": {
 "type": ["image/png", "image/gif"]
 }
 "href": "sharing.html",
 "disposition": "window"
 }
 }
 }
  47. 47. var register = navigator.mozRegisterActivityHandler({
 name: "view", 
 disposition: "inline", 
 filters: {
 type: "image/png"
 }
 });
 
 register.onerror = function () {
 console.log("Failed to register activity");
 }
  48. 48. navigator.mozSetMessageHandler("activity", function (a) {
 var img = getImageObject();
 img.src = a.source.url;
 // Call a.postResult() or a.postError() if 
 // the activity should return a value
 });
  49. 49. Como Instalar pela WEB var install app = navigator.mozApps.install(manifestURL);
 installapp.onsucess = function(data) { //App is installed
 }; 
 installapp.onerror = function() { //App wasn’t installed, info is in // installapp.error.name };
