Reading Text File Located in /res Folder

Recommended Posts

What about read & write to the \res folder?  Is that possible?

e.g., let's say you want to work with something similiar to an INI file? Or read in and write out a JSON file, or an XML file?

For security reasons this is not possible. You cannot create files on the client side, you don't have write permission in that environment. A work around is sending the data you want to store through http requests to the web server, which in turn you can generate a .txt file for the user to download.

So, I will need to use a local storage method? Is there something particularly better for iOS and Android (or compatible with all browsers)?


I need to write a list of multiple strings


e.g. Mountain, Date,  Note


is JSON the best choice?


    {"mountain":"Mount Marcy", "date":"01/15/2016", "note":"Hiked with friends, Debby, Danny, and Rob on a brisk cold day, hovering at around -1 degrees f},
    {"mountain":"Algonquin Peak", "date":"01/22/2016", "note":"Gorgeous day to hike. Took the dogs (gizmo and marley). They did great!"},
    {"mountain":"Mount Haystack", "date":"02/03/2016", "note":"Stayed at John's brook lodge the night before."}

In my own apps written in Smart Mobile Studio I've been using the local storage with JSON data successfully. However, this type of storage is limited in size. It's often about 5 MB, but you never know.


This said, you probably want to use Cordova or PhoneGap to build native-like hybrid web apps. Doing so you have better control over the size constraints. If this isn't still enough you can also use the cordova file plugin to hook into the native file system. I've not yet used this on my own, but judging from the overall quality of official cordova plugins this should work flawlessly.


UPDATE: I forgot to mention thath the cordova file plugin is based on the W3C File API, so chances are high that this approach will soon be available (in some form) in all browsers.

Here's a brief example on how to use it:


  JData = class external
    Value: Integer;

// store data
var TempData: Variant = new JObject;
TempData['Value'] := 1;
Window.LocalStorage.setItem('IdentifierOfChoice', JSON.Stringify(TempData));

// load data
var Data := JData(JSON.Parse(Window.LocalStorage.getItem('IdentifierOfChoice')));

I can probably be written in a more elegant way, but it works fine for my needs.
