Error: file doesn't exist - file-io

Question

Now am working on a project where I need to create a folder in sdcard which am able to do. Also I need to hide/unhide it according to need. The code is working fine on emulator but not in device this is my code what went wrong ?
public class FolderCreate extends MIDlet {
private Form form;
private Display display;
FileConnection fc;
String path;
public void startApp() {
form = new Form("Hello World");
String msg = "Hello World!!!!!!!";
form.append(msg);
display = Display.getDisplay(this);
display.setCurrent(form);
System.out.println("WWWW");
try {
path = System.getProperty("fileconn.dir.memorycard");
System.out.println("Path : "+path+"/sample");
fc = (FileConnection)Connector.open(path+"/ABCD/");
if(!fc.exists())
{
fc.mkdir();
System.out.println("directory created");
}
} catch (IOException e) {
// TODO Auto-generated catch block
//System.out.println("ERROR "+e.getMessage());
Alert alert = new Alert("Alert");
alert.setString(e.getMessage());
display.setCurrent(alert);
}
try
{
//fc = (FileConnection)Connector.open(path+"/sample/");
if(fc.isHidden())
{
fc.setHidden(false);
}
else{
fc.setHidden(true);
}
fc.close();
}
catch (Exception e)
{
Alert alert = new Alert("Alert2");
alert.setString(e.toString());
display.setCurrent(alert);
}
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
System.out.println("Destroyed");
notifyDestroyed();
}
}
The error am getting is: java.io.IOException: file does not exist

Answer 1

Check if path starts with "file://". If not, add the suffix.
path = System.getProperty("fileconn.dir.memorycard");
if (path != null && !path.startsWith("file://")) {
path = "file://" + path;
}

I think you are doing mistake at following line,
path = System.getProperty("fileconn.dir.memorycard");
When you are working with phone and SD-Card you should use e: drive for referring to SD Card as follows,
path = file:///e:/<folder-name>/
