The file chooser API can be called to trigger a native file chooser and return a File API-compatible path to a file. Calling the
getFile method displays a window that displays various file sources
available on the device, such as the file manager, the camera, the sound recorder, etc. (It
mimicks the "Choose file..." window available in a Web browser). Once acquired, the file can be
uploaded to a selected location using the uploadFile method, which
allows to specify a file path, the target URL and a map of parameters via a JavaScript
interface.
This API is intended for use on Android devices only.
The following example illustrates the use of the API.
