title: android mount unmount sd card
body: <p>I am working on an application that scans the sd card. At this time, I am using the emulator of eclipse to test my android application. I have created a virtual sd-card for testing purposes on eclipse.</p>
  
  <p>I want to know if there is any way of un-mounting and then mounting the sd card on the emulator (eclipse) so that I can test my application that when the sd-card is unmounted, it should generate a message etc.. </p>
  
  <p>Can anyone help me here.. </p>
