Question

let’s say I’ve got a file called foo.html sitting (quite comfortable) in my assets/www directory (next to my index.html).

I’d like to copy that file to another location on the device. My first approach window.resolveLocalFileSystemURI("foo.html", cool(), notCool());is not working. Also with a prefix like www/ it won’t.

It would be interesting to know if it is actually possible at all to access files via Phonegap. I’m not convinced and therefore would like to see a code snippet how to obtain a FileEntry for files in the assets directory – if possible.

edit:
Ok now we’ve got a call like this

window.resolveLocalFileSystemURI("file:///android_asset",
  function(entry){
    console.log(entry.fullPath);},
  function(evt){
    console.log(evt.code);}
);

but we’ve get an error with code: undefined (Phonegap v1.2) and code: 1 with v1.0 (code 1 = file not found?!)

Answer 1

You should be able to access the file this way:

window.resolveLocalFileSystemURI("file:///android_asset/www/foo.html", onResolveSuccess, onFail);

You can then use the File API – FileEntry.copyTo or FileEntry.moveTo to actually do the action. Note – you cannot actually write into the assset/www folder, only to an SD card.

Hope this helps
