Use the mksdcard tool to create a FAT32 disk image that you can load into
emulators running different Android Virtual Devices (AVDs) to simulate the presence
of the same SD card in multiple devices. If you do not need a disk image that can be shared
among multiple virtual devices, you do not need to use the mksdcard command.
By default the emulator uses the default image that is generated by and stored with the
active AVD instead.
Usage
mksdcard -l label size file
Options
The following table describes the command-line options of mksdcard
| Option | Description |
|---|---|
-l label |
A volume label for the disk image to create. |
| size | An integer that specifies the size of the disk image to create. If
size is a simple integer, it specifies the size in bytes. You can also
specify the size in kilobytes, megabytes, and gigabytes by appending K, M, or G
to size. For example, 1048576K or 1024M. The
minimum size is 9M. The Android emulator cannot use smaller images. The maximum size is
1099511627264 bytes, which equates to 1023 GB.
|
| file | The path/filename of the disk image to create. The path is relative to the current working directory. |
Example
Create the mySdCardFile.img disk image:
mksdcard -l mySdCard 1024M mySdCardFile.img
Start two emulators with different AVDs. Use the -sdcard flag to specify the name
and path of the disk image you created.
emulator -avd Pixel_API_25 -sdcard mySdCardFile.img emulator -avd NEXUS_6_API_25 -sdcard mySdCardFile.imgFor more information about the
emulator command and its options,
