As current music and media player only play files on /sdcard, if you don't have a real SD card, you can use the following hacked method to enable playing without SD card.

First, of course, you need to make sure /sdcard does existed on the rootfs.

Pay attention: If you are using NFS, you must do the following command in the beginning:

$cd /sdcard $ls -l

Then you can enable it through:

$setprop EXTERNAL_STORAGE_STATE mounted $am broadcast -a android.intent.action.MEDIA_MOUNTED --ez read-only false -d file:///sdcard
