Hi
Actually I am working on vuforia with unity3d. I have device database within vuforia from it i find tow files dat and xml. It is loaded in project. I want this dat and xml file from url and download on device at runtime. I can’t find how to store this file on device. I have write code for downloading as here:
function Start1() {
str=str+“start call”;

var www = new WWW(url);


while(!www.isDone)
{
str=str+"Progress";
Debug.Log("www progress ");
yield  www;

}
if(www.isDone)
{
str=str+"Success";
//str=str+Application.persistentDataPath;
System.IO.File.WriteAllBytes(Application.persistentDataPath,www.bytes);



str=str+"download complete";
Debug.Log("Success");
}
else
{
str=str+"fail";
Debug.Log("Fail");
}


}

Here I reach till str=success but it not function File.WriteAllBytes.I have also tried File.WriteAllBytes(“jar:file://”+Application.streamingAssetsPath+“!/assets/”,www1.bytes);
File.WriteAllBytes(“unity3d:file://”+Application.streamingAssetsPath+“!/assets/”,www1.bytes);
but not succeded. Please help me

In C#, I’d write this, which works fine:

IEnumerator Start () 
{
	using(WWW www = new WWW(url))
	{
		yield return www;
		
		if(www.isDone && string.IsNullOrEmpty(www.error))
		{
			string localPath = Path.Combine(Application.persistentDataPath, "myDownloadedFile.txt"); 
			File.WriteAllText(localPath, www.text);
		}
	}
}
