title: How to run android emulator with sd card
body: <p>I download and build android 1.5r3 source.
  I did 'launch 1' and then 'make'.</p>
  
  <p>And when it is done, I run my emulator like
  out/host/darwin-x86/bin/emulator  -sdcard sd256m.img</p>
  
  <p>But when I click 'Gallery', it said 'No Media Found'.
  I am sure the sd card i created (sd256m.img) has images in there.</p>
  
  <p>Can you please tell me why I don't see any images in the sd card?</p>
