Cant get streaming assets folder to work with the www class

Hello Unity peeps,

So i keep getting the following error with my code:

You are trying to load data from a www stream which had the following error when downloading.
malformed

And heres my code:

    string url = Application.streamingAssetsPath + "/" + textureName;
	WWW www = new WWW(url);
	
	yield return www;

	gameObject.renderer.material.mainTexture = www.texture;     //error points to this line

It works fine if i use a http address for the url which makes me think i might using it wrong but from reading the docs i thought this was okay?!?! Anywho any help would be great, im using unity 3.5.7, on a mac building for iOS and Android.

string url = “file://”+Application.streamingAssetsPath + “/” + textureName;

Try that
