The mksdcard tool lets you quickly create a FAT32 disk image that you can load in the emulator, to simulate the presence of an SD card in the device. Here is the usage for mksdcard:

The table below lists the available options/arguments




A volume label for the disk image to create.


An integer that specifies the size (in bytes) of disk image to create. You can also specify size in kilobytes or megabytes, by appending a "K" or "M" to <size>. For example, 1048576k, 1024m.


The path/filename of the disk image to create.

Once you have created the disk image file, you can load it in the emulator at startup using the emulator's -sdcard option. For more information, see Android Emulator.

emulator -sdcard <file>
