Does Nexus 7 implement the external storage somehow? Is the lack of the external SD (for Nexus 7)
related to the external storage as a term at all? Can the lack of external SD be a limitation
when designing/developing some sorts of applications?
As Nexus 7 doesn't have a External Memory Storage Card but its internally manage it. When you call Environment.getExternalStorageDirectory()
then its return to path /mnt/sdcard/
which is in-built their as a External Storage.
So there is no issue for developing application.
