There is 2 files, tab1.js and myList.txt.
My only problem is that I can't write to myList.txt.
`
//this one to read the file
var f = Titanium.Filesystem.getFile(Titanium.Filesystem.resourcesDirectory, 'myList.txt');

//this one to write to file
var file = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory,'myList.txt');

var resources = JSON.parse(f.read().text);
var contents = f.read();

** test **
Ti.API.info('file = ' + f);
Ti.API.info('exists = ' + f.exists());
Ti.API.info('size = ' + f.size);

Ti.API.info('readonly = ' + f.readonly);
Ti.API.info('writeable = ' + f.writeable);
Ti.API.info('name = ' + f.name);

Ti.API.info("contents blob object = "+contents);
Ti.API.info('contents = ' + contents.text);

* end test **

function loadValues(){

 for (var i=0; i<resources.list.length; i++){
     var row = Ti.UI.createTableViewRow({
         title:resources.list[i].stuff,
         className:'newRowClass'});
    data.push(row);
     }

}
addButton.addEventListener('click', function(e)
{

var row = Ti.UI.createTableViewRow({});
var label = Ti.UI.createLabel({});
label.text = tf1.value;

       while(resources.list[counter].stuff != "")//if there is something, loop until empty
         {
               counter++;
     }
     resources.list[counter].stuff = label.text;

file.write(JSON.stringify(resources));
    row.add(label);
tableView.insertRowBefore(0,row);

});
This is myList.txt
{"list":[
{"Row":"1","stuff":""},
{"Row":"2","stuff":""},
{"Row":"3","stuff":""},
{"Row":"4","stuff":""},
{"Row":"5","stuff":""}
]}

If I only use …resourcesDirectory, 'myList.txt');, it is ok on iPhone emulator, but not on android emulator or Android device.
But if I use …applicationDataDirectory,'myList.txt');,it happens something strange-I see that file is existing, but I get error nullPointerException, just like there is not an object..??? I get this error on both emulators and android device. I dont understand.. Can someone please try to explain what is with my code when read,and when write and tell me how to write to file? Should I specify what to write to file more times? If so, how is it possible that code is working if using …resourcesDirectory, 'myList.txt'); Please help!

Thanks!
