How to use requestFileSystem with angularJS(ionic)

window.requestFileSystem is not defined if i put it in a service.Code:
var fileModule = angular.module("fileModule",['ionic']); fileModule.factory('filerw',function($window){ var access = $window.requestFileSystem($window.LocalFileSystem.PERSISTENT,0,requestFileSystemSuccessHandler_,fileError); ... });
no matter it’s window or $window,requestFileSystem and LocalFileSystem are undefined.The code works fine in normal JS.

Can you tell me how you solved it :slight_smile: thank you!

No problem. requestFileSystem doens’t exist until the device is ready, so just a little change.
ionic.Platform.ready = function(){window.requestFileSystem(…)};

.service(‘fileSystem’, function($ionicPlatform,$cordovaFile,$window) {

return {
  	test: function(){
  		return $ionicPlatform.ready(function() {
