How to access external Storage in Tizen Smart TVs - api

Question

I need yout help to find out how to write and read files from external usb storage from Tizen Smart TVs. Problem starts when detecting it
`
/**
* Hello World Sample Project
*/
// import Label component
var Label = caph.require('ui.base.component.Label');
caph.app.addScene('main', $class({
$extends : caph.require('ui.base.Scene'),
// oncreate is called when the scene is created
oncreate : function() {
// add "Hello World"
this.addChild(new Label({
text : 'Hello World',
size : [ 500, 100 ],
position : [ 300, 400 ]
}).setTextSize('72px').setStyle({
backgroundColor : 'red',
color : 'white'
}));
/// Here the filesystem showd show me all the storages
tizen.filesystem.listStorages(checkCorruptedRemovableDrives);
}
})).run();
`
And here is the Success callback, this show me how much storages I have.
`
/* Success event handler */
var checkCorruptedRemovableDrives = function(storages) {
/// Here I will kow how much storages I have
console.log(storages.length);
for (var i = 0; i < storages.length; i++) {
if (storages[i].type != "EXTERNAL")
continue;
if (storages[i].state == "UNMOUNTABLE")
console.log("External drive " + storages[i].label + " is corrupted.");
}
};
`
Here is the method thrown when there are errors, this is never called.
var checkCorruptedRemovableDrivesError = function(storages){
console.log("Error");
}
Now, the console output is aways a simple 0 meanning I have no storage (but I have the internal one and two usb ones mounted).
Has Anyone faced this problem or have any Idea on how to solve it?

Answer 1

Samsung Tizen TV always uses "removable2" as label for USB.
So you don't need to use listStorage and getStorage.
Multiple USBs are distinguished as "removable2/sda1", "removable2/sda2"
tizen.filesystem.resolve("removable2", function(e){
e.listFiles(function(r){
for(i = 0; i < r.length; i++){
tizen.filesystem.resolve(r[i].path + r[i].name, function(t){
//You resolve USB root. Do something you want with USB.
}, function(t){
console.log("resolve error for " + r[i].path + r[i].name);
console.log(t);
}, "rw"); //you should use rw permission, to write something in usb.
}
});
},function(e){
console.log("removable2 resolve error");
console.log(e);
}, "r"); // permission should be given as r for removable2
Here is test app made by me. and you can check how to use SDK 1.5
http://www.samsungdforum.com/SamsungDForum/ForumView/3ad8bd6023af18a7?forumID=d88a711f47dc6e9f
This app is working in both of TV and SDK 1.5

Answer 2

Do you use Web Simulator?
APIs don't work in Web Simulator properly. It can't simulate things well.
When I check listStorage in 'emulator', it throws list of storages.
but even though I can get list of storage, I can't use it in filesystem. It is bug of SDK 1.4.
SDK 1.5 will have test features for USB storage, and it is planned to release in a month. Wait for a month :(
