Navigator.getDeviceStorage()
This API is available on Firefox OS for privileged or certified applications only.
Summary
The getDeviceStorage
method is used to access some storage area available on the device.
This method gives access to a storage area from the device's default storage, that is the storage area whose .default
attribute is true
. This is controlled by the user via Settings App > Media Storage > Default media location (e.g. sdcard, internal memory, etc.) Alternatively, you can use the getDeviceStorages
method, which returns an Array
of DeviceStorage
objects, one per physical storage area.
Note: To be able to use a storage area, the application must declare it in its application manifest. For example, if the application wants to access the sdcard
storage area, it must have the "device-storage:sdcard
" permission in its manifest.
