title: Android Emulator sdcard push error: Read-only file system
body: <p>I am developing under Android 1.6 (Android SDK 2.1).
  I create a avd by using avd manager in Eclipse.
  When I launch this avd, I found that the /sdcard directory's permisson is "d---------".
  So I can't push file to the sdcard.</p>
  
  <p>Does anyone know how to solve this problem?</p>
