java.io.FileNotFoundException while creating Bitmap from a File Object on Android

Question

I get an Object containing a File:

public class Ordo implements java.io.Serializable{

static final long serialVersionUID = 11223344;

public String id;
public String name;
public String date;
public String status;
public File thumbnail;

and I need to convert this File into a Bitmap to be viewed on an Activity. I'm doing the following:

thumbnail = list.getFileFromId(vid);
    Bitmap pic = null;
    try {
        byte[] buffer = new byte[8192];
        int bytesRead;
        FileInputStream input = new FileInputStream(thumbnail);
        ByteArrayOutputStream stream = new ByteArrayOutputStream();

        while((bytesRead = input.read(buffer)) != -1){
            stream.write(buffer, 0, bytesRead);
            }
        pic = BitmapFactory.decodeByteArray(stream.toByteArray(), 0,    stream.size());
    } catch (Exception e) {

        e.printStackTrace();
    }

but I get the following error:

it seems that I need to create a physical file from my File Object... any idea how I can solve that ?

Thanks for your answers.

Where are you saving your file? Update with that code. Also have you added proper permissions in manifest? — sanedroid
Do not use a byte array output stream but directly use BitmapFactory.decodeFile(thumbnail); — greenapps
my file is not saved physically on the hard drive, it is sent by the server in a Java Object but may be this is not the simpliest way... — tiamat

Finally I'll try to find another way by including a Bitmap instead of a File in my Object....it will be easier. thanks for your answers anyway.
