Subject RE: Questions about FileSystem documentation and paths

If you want to move this to comments on the blog entry, that would be cool. 

Can you explain a bit more? I'm not seeing which step ....

Oh... so resolveLocalFileSystemURL will call the second argument on success and the third
on failure. 

Yeah - that's significant enough for me to rewrite the sample and blog post.

Thanks for putting together this blog post Ray!

Assume this is addressed in
https://github.com/apache/cordova-plugin-file/pull/59? (Which is an awesome
change! Thanks Kerri!)

As a nit: you can simplify your code a bit by skipping the .getFile() call:
resolveLocalFileSystemURL(cordova.file.dataDirectory + fileName, appStart,
downloadAsset)
