Question

In the below program i get the exception as shown below.Basically what i am trying to do is i am copying a file from a remote system to the device.but when saving to the memory card both on the emulator and device i am hitting an exception.The below exception is from the emulator where i can say that the memory card is not attached to the emulator and so the exception.but will the code work for a physical device.

How to make the code work on emulator and the device

                  sftpChannel.get("/root/a.txt","/mnt/sdcard/download/dd.txt");
                  /*OR What shoud the abobe statement be **/
              //sftpChannel.get("/root/a.txt",ofile); or this statement is correct

                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                         System.out.println(e.toString());
                }


                sftpChannel.exit();
                session.disconnect();
            } catch (JSchException e) {
                e.printStackTrace(); 

            } catch (SftpException e) {
                e.printStackTrace();

            }

Do this for file creation ; a better and safer way than yours

File dir = new File(Environment.getExternalStorageDirectory(),"/Downloads/");
dir.mkdirs();
String strFileName = "dd.html";
File file = new File(dir,strFileName);
