Phonegap - jQuery Mobile - Download/Save/Load File

Question

I'm using Phonegap with jQuery Mobile and have the following use-case:

• I want to download a file from a remote server via JSON.
• Store the file on local filesystem of the mobile device (to work also offline).
• Target platforms: iOS, Android, maybe Windows Phone and BlackBerry.
• Load file from filesystem.

What's the recommended way to do that?

• Phonegap.FileWriter? Is there also a way to save it to "assets/www../"?
• Phonegap.Storage?

Or is there any better way?

Answer 1

• Use XHR to download the JSON data.
• Use the FileWriter to save the file to the file system.
• Use the FileReader or XHR to read the JSON file from the file system.

No, you cannot save the file to assets/www as it is not writeable.
