this is my first question here, so sorry if I'm writing bad my request. I'm creating a project with Sencha Touch 2.4.1 and PhoneGap (my main target is Android), using the command
sencha app build native
to package. To be short, I need to request the file system and then download some file (images). According to posts like this, I'm trying to use the "getFile()" function before start downloads, but even a simple code like this gives me troubles:
Ext.define("MyApp.utils.Globals", {
singleton: true,
alias: 'widget.globals',
config: {
// Some vars not related to problem
},
constructor: function(config) {
this.initConfig(config);
},
initFileSystem: function(quota) {
if(Ext.browser.is.PhoneGap && !Ext.os.is.Desktop) {
Ext.device.FileSystem.requestFileSystem({
type: window.PERSISTENT,
size: quota,
success: this.initFsSuccess,
failure: this.initFsFailure
});
} else {
window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
window.requestFileSystem(window.PERSISTENT, quota, this.initFsSuccess, this.initFsFailure);
}
},
initFsSuccess: function(fs) {
// Save file system reference
MyApp.app.fS = fs;
alert("FS: " + fs.root.fullPath); // This line outputs "FS: undefined"
fs.root.getFile("newFile.jpg", {create: true, exclusive: false}, function(fileEntry){ alert("GetFile OK"); }, function(error){ alert("GetFile ERR"); });
},
initFsFailure: function(err) {
console.log("File System Error " + err.code);
Ext.Msg.show({
title: 'FyleSystem Error',
message: 'Can\'t access to FileSystem',
buttons: [ { itemId: 'ok', text: 'Ok', ui: 'decline' } ],
fn: Ext.emptyFn
});
}
});
When I try to access file system's root full path (like in the first alert in "initFsSuccess" function), I get undefined as value. Furthermore, the "getFile" function stops executing (no callback is invoked, success or failure) and in LogCat I'm able to see this:

Thank you all in advice for any help, I'll try to provide any other infos/specs if needed.
Found the solution (even if I don't known why...)! This is what I've done:
1) In my "app.js" file I've removed the
'Ext.device.FileSystem'
line from the "requires" section;
2) Replaced the body of the "initFileSystem()" function reported in first post, with this one
window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
window.requestFileSystem(window.PERSISTENT, quota, this.initFsSuccess, this.initFsFailure);
It works in:
