The API at this point is very poorly named -- it makes perfect sense for the original device configurations where all media storage was on the external SD card. When manufacturers started putting that storage into the internal device, the name became unfortunate. Don't get stuck on the name, just what it is supposed to mean.
This is explained in the doc: http://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory() And this was the first step of complexity on that name: http://developer.android.com/reference/android/os/Environment.html#isExternalStorageRemovable() And Android 3.0 introduces even more fun: http://developer.android.com/reference/android/os/Environment.html#isExternalStorageEmulated() On Mon, Feb 28, 2011 at 2:13 PM, Indicator Veritatis <mej1...@yahoo.com>wrote: > Is it a typo is the CDD requirement really this backwards?
