ngCordova $cordovaFile filePath dataDirectory

1

I am trying to save sample file to a dataDirectory but keep getting
FileError {code: 5} which is if i am right to use this document to see what is wrong
https://github.com/apache/cordova-plugin-file/blob/master/doc/index.md
5 ENCODING_ERR
if as filePath i just pass log2.txt it file is sucessfully written
also i have tried filePath =$window.cordova.file.dataDirectory+‘log2.txt’ but i get the same error
$window.cordova.file.dataDirectory filePath is right and points to directory to which it should point
im using telerik app builder to test it and in my case it is
C:/Users/VjerN/Documents/Telerik/Icenium/Simulator/Storage/Temporary/dataDirectory
on physical device it is
file:///data/data/com.coolappz.canelio/files/

So any help what to do?

var blob = new Blob(["sample text"], { type: 'text/plain' });
    $cordovaFile.writeFile($window.cordova.file.dataDirectory+'/log2.txt', blob, { 'append': false }).then(function (result) {
        // Success!
        console.log("writing sucess");
    }, function (err) {
        console.log(err);
        console.log("writing error");
        // An error occurred. Show a message to the user
    });

i have also tried this
which also aint working
as native url i get
file:///%simulator_persistent_root%/dataDirectory/
and on physical device it is
file:///data/data/com.coolappz.canelio/files/

window.resolveLocalFileSystemURL($window.cordova.file.dataDirectory, function (dir) {
    console.log(dir.nativeURL);
    $cordovaFile.writeFile(dir.nativeURL+'log2.json', blob, { 'append': false }).then(function (result) {
        // Success!
        console.log("writing sucess");
        $cordovaFile.readAsText('log2.json').then(function (sucess) {
            console.log("sucess reading file");
            console.log(sucess);
        }, function (error) {
            console.log(error);
        });
    }, function (err) {
        console.log(err);
        console.log("writing error");
        // An error occurred. Show a message to the user
    });
});

I faced the same problem here but I get it working with the following code:

function writeFile(fileName, data, options) {
        var deferred = $q.defer();
        $window.resolveLocalFileSystemURL($window.cordova.file.dataDirectory,
            function(dir) {
                dir.getFile(fileName, {
                    create: true
                }, function(fileEntry) {
                    fileEntry.createWriter(
                        function(fileWriter) {
                            if (options['append'] === true) {
                                // Start write position at EOF.
                                fileWriter.seek(fileWriter.length);
                            }
                            fileWriter.onwriteend = function(evt) {
                                evt.fileEntry = fileEntry;
                                deferred.resolve(evt);
                            };
                            fileWriter.write(data);
                        },
                        function(error) {
                            deferred.reject(error);
                        }
                    );

                }, function(er) {
                    deferred.reject(error);
                });
            });
        return deferred.promise;
    }

Hope it helps!
