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.

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
