FIle API - Phonegap?

Question

Can anybody explain how to list a folder of files on a page using the Phonegap File API for Android?

I would like to list all .mp3 files if possible, but have read through all the phonegap docs (http://docs.phonegap.com/en/1.0.0/phonegap_file_file.md.html) and cant figure it out at all!

Answer 1

it is a bit of a pain in the @$$ but doable. Start with this code:

document.addEventListener("deviceready", onDeviceReady, false);

// PhoneGap is ready
//
function onDeviceReady() {
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, fail);
}

function onFileSystemSuccess(fileSystem) {
    fileSystem.root.getDirectory("Music", {create: false, exclusive: false}, getDirSuccess, fail);
}

function getDirSuccess(dirEntry) {
    // Get a directory reader
    var directoryReader = dirEntry.createReader();

    // Get a list of all the entries in the directory
    directoryReader.readEntries(readerSuccess,fail);
}

function readerSuccess(entries) {
    var i;
    for (i=0; i<entries.length; i++) {
        // Assuming everything in the Music directory is an mp3, go nuts
        // otherwise check entries[i].name to see if it ends with .mp3
    }
}

I'm writing all this example code outside of an IDE so there may be bugs but that should get you going.
