The search interface of Firefox OS

Defined by manifest

        {
          "name": "My App",
          "description": "My elevator pitch goes here",
          "launch_path": "/",
          "icons": { "128": "/img/icon-128.png" },
          "developer": {
            "name": "Your name or organization",
            "url": "http://your-homepage-here.org"
          }
        }
      

App manifest

Three levels of access…

  • Privileged apps - reviewed by the App store, uses a Content Security Policy, hosted on trusted server
  • Certified apps - part of the OS, only by Mozilla and partners

App permissions

Using WebAPIs to make the web layer more capable

Install apps from the web

        var installapp = navigator.mozApps.install(manifestURL);
        installapp.onsuccess = function(data) {
          // App is installed
        };
        installapp.onerror = function() {
         // App wasn't installed, info is in 
         // installapp.error.name
        };
        

Battery API

          var b = navigator.battery;
          if (b) {
            var level=Math.round(battery.level * 100) + "%",
                charging=(battery.charging) ? "" : "not ",
                chargeTime=parseInt(battery.chargingTime / 60, 10),
                dischargeTime=parseInt(battery.dischargingTime/60,10);
            b.addEventListener("levelchange", show);
            b.addEventListener("chargingchange", show);
            b.addEventListener("chargingtimechange", show);
            b.addEventListener("dischargingtimechange", show);
          }
        

Web APIs (privileged apps)

          var request = navigator.mozContacts.save(contact);
          request.onsuccess = function() {
            // contact generated
          };
          request.onerror = function() {
            // contact generation failed
          };

Sending a number to the phone

        var call = new MozActivity({
          name: "dial",
          data: {
            number: "+1804100100"
          }
        });
      

Get an image from the phone (1/2)

        var getphoto = new MozActivity({
          name: "pick",
          data: {
            type: ["image/png", "image/jpg", "image/jpeg"]
          }
        });
  

Get an image from the phone (2/2)

        getphoto.onsuccess = function () {
          var img = document.createElement("img");
          if (this.result.blob.type.indexOf("image") != -1) {
            img.src = window.URL.createObjectURL(this.result.blob);
          }
        };
        getphoto.onerror = function () { // error
        };
