Not getting image from Persistant path in Android

I have a script to take screenshot and save that image and to show that image in a plane.

But not getting that texture.

 private string path;

 void Start () {
        path = Application.persistentDataPath;
     }

 void captureScreeshot(){ 
     Application.CaptureScreenshot(path + "/Screenshot.png");
     alert.text = "saved";
     StartCoroutine(saveScreenshot()); 
     onetimeBool = false;
 }
 IEnumerator saveScreenshot(){
     WWW imgfile = new WWW("file://" + path+ "/Screenshot.png");
     yield return imgfile;
     if(imgfile.error==null){
         img = new Texture2D(200, 200, TextureFormat.RGB24, false); 
         imgfile.LoadImageIntoTexture(img);
         alert.text = "got image";
         GameObject.Find("plane").renderer.material.mainTexture = img;
         
     }else{
         print(imgfile.error);
     }
 }

Images gets saved.

But I cannot open (load) image in windows system and android.

Getting error in system :

Couldn't open file /Users/ether/AppData/LocalLow/Company/Project/Screenshot.png

How to get it ???

i think android needs to use jar preceding the file://

  WWW imgfile = new WWW("jar:file://" + path+ "/Screenshot.png");

hmm reading the unity script reference: http://docs.unity3d.com/Documentation/ScriptReference/Application.CaptureScreenshot.html

It says "On mobile platforms the filename is appended to the persistent data path."

try:

 Application.CaptureScreenshot("Screenshot.png");

hmm...Only other thing I can think of is that the file hasn't been saved before you try accessing it. Try adding:

 yield return new WaitForSeconds(2.0f);
 
 WWW imgfile = new WWW("file://" + path+ "/Screenshot.png");
     yield return imgfile;
     if(imgfile.error==null){
        img = new Texture2D(200, 200, TextureFormat.RGB24, false); 
        imgfile.LoadImageIntoTexture(img);
        alert.text = "got image";
         GameObject.Find("plane").renderer.material.mainTexture = img;
  
     }else{
        print(imgfile.error);
     }
