Create and manage sdcard image files for the android Simulator

Mksdcard-l test 10 m c:/Android/test1.img

Create a simulated sdcard image file.

Start the simulator and run the following command:

After the simulator starts, open a new command window, copy a file to the sdcard image, and execute the command:

Then, retrieve the test file from the sdcard image and run the following command:

ADB pull sdcard/test.jpg D :/
