Filesystem and emulator

Tony_T_ · ‎03-07-2016

I want to create a windows app. On app initialize it has to check if a directory exist. If not create said directory. My problem is I - How do i test this condition in emulator. Does emulator support creating directory and sub directory..Do I have to build window app in order to check my code?

I get error.code of 1. when using following code in emulator

function onDeviceReady() {
window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail); }

   function fail(error) {
       console.log("failed to get filesystem");
alert("what is wrong "+error.code)
   }

   function gotFS(fileSystem) {
       console.log("filesystem got filesystem");
       fileSystem.root.getDirectory("mydir", {
           create : true,
           exclusive : false
       }, dirReady, fail);
   }

   function dirReady(entry) {
       console.log("filesystem in dir ready");
       window.appRootDir = entry;
       console.log(JSON.stringify(window.appRootDir));
   }

You have build the app and install on device to test the app using File API.

Below are some examples for app that use file API to read/write to files: https://github.com/krisrak/html5-cordova-samples
