The problem we have here is that getExternalStorageDirectory does NOT return the location of the sd card. In fact it has nothing to do with sd cards and never has. From the docs:
*"Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer."* http://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory() It is that part of the file system that is mounted when you attach an external device such as a desktop computer via the USB port. There is *NO* documented way in Android to enumerate removable storage. On Friday, March 8, 2013 9:21:38 PM UTC, [email protected] wrote: > > Yes, have read the documentation.
