probem with yield return www

Need help with the c# code. problem is in yield return www. everything works great in unity editor and standalone exe file, but on android and webplayer it doesn't work. This code gets some json information from localhost and with "for" loop assigns json values to some variables. first yield return request; works great, but there is a problem on second yield return www;. In first yield i get names and scores and on second yield i get picture links. The links look like "graph.facebook.com/v2.1/816783911674988/picture/". If i change the code N["picture"].Value to something like this "http://www.something.com/images/somthing.jpg" everything works fine. i don't understand what i am doing wrong.

Code (CSharp):

1. IEnumerator GetData()
2.         {
3.             WWW request = new WWW("http://localhost/disp.php");      
4.             yield return request;      
5.             if (request.error == null || request.error == "")
6.             {          
7.                 var N = JSON.Parse(request.text);
8.                 for (int i = 0; i <=9; i++)          
9.                 {  
10.                     if(N[i] != null)
11.                     {
12.                     Fname.text = N[i]["name"].Value;
13.                     Fscore.text = N[i]["score"].Value;
14.  
15.                     WWW www = new WWW(N[i]["picture"].Value);
16.                     yield return www;
17.                     fpicture.mainTexture = www.texture;
18.                     GameObject itemleft = NGUITools.AddChild(friendslistgrid,itemprefab);                              
19.                     }
20.                     friendslistgrid.GetComponent<UIGrid>().Reposition();
21.                 }          
22.             }

Please halp.

 

At first glance, the former seems more a folder than a picture (no .jpg).
Can you print "N ["picture"].Value" and copy/paste it in a browser?

 

In unity editor and standalone everything works. Yes, when i copy the N ["picture"].Value in browser i can see the picture.

 

During coding in first stages when i was testing it was working on android, but somehow when i finish the code it didn't work at all. i changed something and now I've got this problem. I don't remember what changes I made. but i thing that problem is in yield return www; because on editor it needs some time to make list and on android it make it immediately.

 

if you add this after the www yeld?

Code (CSharp):

1. if (!String.IsNullOrEmpty(www.error))
2.             Debug.Log(www.error);

 

conscole is empty

 

Have you tested different Android phones/versions?

 

On two android phones. same issue.

 

I tryed in the webPlayer and end up with a failed download image "?" while in Editor works fine.
I got this error in the webplayer log:

Platform assembly: D:\Users\Fra\AppData\LocalLow\Unity\WebPlayer\player\Release3.x.x\Data\lib\CrossDomainPolicyParser.dll (this message is harmless)
Failed downloading graph.facebook.com/v2.1/816783911674988/picture/

I found a thread talking of similar issues working in Editor but not in webplayer:
http://forum.unity3d.com/threads/crossdomain-problems.64133/

 

Implications for use of the WWW class
The Unity webplayer expects a http served policy file named crossdomain.xml to be available on the domain you want to access with the WWW class, (although this is not needed if it is the same domain that is hosting the unity3d file).

The solution is: always use the "http://" part. It works in the webplayer now.

you are a great man. I add the "http://" to my links and it work now. thank you very much to your support!!!
