[Shih-Chiang Chien [:schien] (UTC+8) (use ni? plz)]

In Bug 1126694 DeviceStorage WebAPI can notify the activity of adding/removing storage areas reported by nsVolumnService. Now Device Deck can enumerate and monitor the available memory devices using following sample code, with 'device-storage:sdcard' permission declared:

// list all available memory devices
let storages = navigator.getDeviceStorages('sdcard');

// monitor the change of memory device
navigator.deviceStorageAreaListener.addEventListener("storageareachanged", function(e) {
  switch (e.operation) {
    case 'added':
      addMemoryDevice(e.storageName);
      break;
    case 'removed':
      removeMemoryDevice(e.storageName);
      break;
    default:
      break;
  }
});

function addMemoryDevice(storageName) {
  // Get the corresponding DeviceStorage object for that memory device.
  let storage = navigator.getDeviceStorageByNameAndType(storageName, 'sdcard');

  //... create new storage device or make storage as available
}

function removeMemoryDevice(storageName) {
  //... mark storage as unavailable
}
