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.
The mksdcard
tool provided in the Android SDK Tools package
is located in android-sdk/emulator/mksdcard
.
If you don't need a disk image that can be shared
among multiple virtual devices, you don't 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
To use the mksdcard
tool, use the following command:
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, or gigabytes by appending K, M, or G
to size. For example, |
file | The path/filename of the disk image to create 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.img
