Answer 1

Finally found it at http://groups.google.com/group/android-developers/browse_thread/thread/c1a385226f3df482.

It is a one-liner:

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse
("file://"
+ Environment.getExternalStorageDirectory())));

Answer 2

am broadcast -a android.intent.action.MEDIA_MOUNTED -d file:///mnt/sdcard

This command can be used to update the SD Card without rebooting the device

Answer 3

One can also invoke from the shell:

am broadcast -a android.intent.action.MEDIA_MOUNTED -d file:///mnt/sdcard
