cordova - PhoneGap (Android) Delete Directory

Question

I'm trying to delete a directory and it's contents with PhoneGap on Android using:

deleteDirectory = function deleteDirectory(uri) {
    uri = uri.substring(0, uri.lastIndexOf('/'));
    return $.Deferred(function (def) {
        fileSystem.root.getDirectory(uri, {
            create: false
        }, function (directory) {
            directory.removeRecursively();
            def.resolve();
        }, function (error) {
            resolveError("Error deleting directory: ", error, def);
        });
    }).promise();
}

with the following error: File No Modification Allowed Error

I've confirmed this permission is set:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Where else should I be looking?

I have done it with this approach:

    function ClearDirectory() {
        window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, fail);
        function fail(evt) {
            alert("FILE SYSTEM FAILURE" + evt.target.error.code);
        }
        function onFileSystemSuccess(fileSystem) {
            fileSystem.root.getDirectory(
                 "yours/dir/ect/ory",
                {create : true, exclusive : false},
                function(entry) {
                entry.removeRecursively(function() {
                    console.log("Remove Recursively Succeeded");
                }, fail);
            }, fail);
        }
    }
