How To Format/wipe Emulator's Sdcard(/mnt/sdcard)

I just want to know how to wipe the virtual sdcard in the android emulator.

Solution 1:

With the expected caveats and warnings about using commands in the "rm -r *" family, you can also use: adb -e shell rm -r /mnt/sdcard/*

Solution 2:

You can do it easily from Android Settings app: "Storage"->"Erase SD card".

Solution 3:

Delete the sdcard form the AVD manager and add a new one!?

Solution 4:

You could try deleting this file: sdcard.img in the emulator directory. That's where it stores the info.

Just rename at first it in case it crashes things. I haven't tested this before.

Solution 5:

When you launch the emulator there's a checkbox to wipe user data.
