Can not read an apk file on emulator on SDK 1.1

[GoogleCodeExporter]

Hi,

It seems my code cannot read an apk File I have created on the Android 
emulator.

- First off, I created an sdcard with command 'mksdcard ...'
- then I run this code: 

------------- Begin Cut Here --------------->

File tmpdir = new File(tmpdirpath+name);

if (!tmpdir.exists()) 
 {
  boolean b = tmpdir.mkdirs();
 } 
else
 {
  if (!tmpdir.isDirectory()) 
   {
    throw new RuntimeException("here : the tmp dir conflicts");
   }
 }
File apk = new File(tmpdirpath + name + "/" + name + ".apk");
if (!apk.exists())
 {
  apk.createNewFile();
 }
// with name = name of my apk file.

------------- End Cut Here --------------->

- The apk file is successfully created on a temporary directory on /sdcard,
but I have no permissions to read it: 

- - - - r w - r w -

- I tryed to change them:
#adb shell
# chmod 777 myFile.apk

No error but permissions remain the same  

- - - - r w - r w -

and I get the following exception:
