The document provides an introduction to WebAPI in 3 sections: 1. It describes the Boot to Gecko project which is based on open standards and open source code to avoid platform-specific APIs. 2. It explains there are three levels of app permissions - web apps have basic access, privileged apps have more access, and internal apps certified by Mozilla have the most access. 3. It gives examples of privileged and certified APIs, how to access the battery API, and mentions calling, SMS, and manifest files.
Introduction to WebAPI- FirefoxOS
- 2. 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.
- 3. No longer need to learn and develop against platform-specific native APIs.
- 5. GONK Lower level operating system, consisting of a Linux kernel and HAL (Hardware Abstraction Layer).
- 6. GECKO The application runtime. The rendering engine in Firefox for HTML5, CSS & JavaScript. Implements a number of APIs.
- 7. GAIA GAIA ux concept of B2G
- 10. The three levels of permission, in brief, are: Web apps: These only have a basic level of permissions, and don't have access to privileged or internal APIs. Privileged apps: These have all the permissions of web apps plus more. Hosted apps can't be privileged — they must be packaged apps. Internal (certified) apps: These have all the permissions of privileged and web apps plus more. Certified/internal apps can only be installed on a device by Mozilla or a device vendor; not 3rd party developers.

- 12. BATTERY //First, get the object var battery = navigator.mozBattery; //Check the current level var batteryLevel = battery.level * 100 + "%"; //Listen to events battery.addEventLister("levelchange", setStatus, false); battery.addEventLister("chargingchange", setStatus, false);
