I have a strange error in my App.

In my app it is possible to download a zipFile, read the content as what it is and also delete it. Its doesn't matter what exactly it is.

Problem: Only on the Motorola Xoom (version 4.0.4) I can download the file, unzip it, I can read the data and I can delete everything. But if I try to Download the file again and while it unzip the file and copy the files to SD-Card it crashes with the error EBUSY (Device or resource busy).

  1. Why is it working only the first time?
  2. What means that error?
  3. Why i get this error only on the Xoom?

I can't find any solution for that. On all other devices it works fine, no errors or problems.
