Hi Sonal,

There are two available roots.

1) file:///store and

2) file:///SDCard/

You know the mechanism for SDCard. And folowing is the way to write & read file on phone memory.

FileConnection fconn;

 fconn = (FileConnection)Connector.open("file:///store/home/user/myFile.txt", Connector.READ_WRITE);

You can view this file under menu of Home Screen -> Media -> menu -> Explore. Here you will find

1) Media Card and

2) Device Memory.

go to Device Memory -> home -> user ->myFile.txt. You can also create folder of your application under this hierarchy like -> store/home/user/{myAppNameHere}.

Hope it helps..!

Thanks & Regards,

Thanks Kanaksony,

But it throws File System Exception on 4.3 JDE. Is there any setting to set on JDE to access phone memory ?

I used

FileConnection directory = (FileConnection) Connector.open ("file:///store/home/Son/" ,Connector.READ_WRITE); 
            if (! directory.exists())
            {                   
                directory.mkdir();               
            }

Hi Sonal,

I wrote this code for picking up the image from the SDCard.

May be it will help you.

  btnBrowse = new BigButtonField("Browse",Color.BLACK,null)
  {
    protected boolean navigationClick(int status, int time) 
    {
     try{
           fieldChangeNotify(1);
           FileSelectorPopupScreen fps = new FileSelectorPopupScreen("SDCard/");
           fps.pickFile();
           javax.microedition.io.file.FileConnection fileConnection = (javax.microedition.io.file.FileConnection)javax.microedition.io.Connector.open("file:///"+fps.getFile());
            java.io.InputStream in = fileConnection.openInputStream();
            byte[] data = new byte[(int)fileConnection.fileSize()];
            in.read(data,0,data.length); 
            selectedIcon = EncodedImage.createEncodedImage(data, 0, data.length);
         }
         catch(Exception ex){}
      return true;
      }
    
 };
