Difference between isExternalStorageRemovable and isExternalStorageEmulated

Question

Environment.isExternalStorageRemovable() was added in API 9

And Environment.isExternalStorageEmulated() was added in API 11

isExternalStorageRemovable returns true when getExternalStorageDirectory's path is removable or not, more like a SD Card and if it return false, its internal storage and can never be removed physically.

And isExternalStorageEmulated is just do opposite of isExternalStorageRemovable ?

Now, my question is whats the difference ? Is it just different name with opposite output ?

Answer 1

isExternalStorageEmulated() == true means that there is no real SD card and it is just emulated (Nexus 5 for example). if the external storage isn't emulated isExternalStorageEmulated() == false then it can either be removable or not that is why we have isExternalStorageRemovable()
