Android: absolute location of External sd-card?

That's been asked before on SO, use the search. In short, 'external storage' is more like 'shared storage' and it may or may not be implemented by an actual SD card. Some devices have an additional SD card, not used as external storage.

If that is what you are asking for, there is currently no public API for accessing its mount location, and it varies between devices. You can check proc/mount to see what is currently mounted and go from there.

– Nathan Moos Aug 31 at 3:35 /mnt/sdcard is usually the path to external storage, but I don't think it's universal. Additional SD cards (such as on the Xoom or Iconia) are mounted some place else. I've seen references to 'secondary external storage', but no API for it in the SDK.

– Nikolay Elenkov Aug 31 at 3:57 Yes, in devices like Xoom, Galaxy Tab, Asus Tablets, Samsung Galaxy S2 and many more. /mnt/sdcard usually points to internal storage; not external sd-card storage. – Farhan Aug 31 at 8:22 Thanks Nikolay for your answer.. I too have found that there is currently no public API for accessing the mount location of a removable sd-card in devices where getExternalStorageDirectory() returns the path of internal shared storage.

Looks like I have to try making my own library :) – Farhan Aug 31 at 8:23 Try the /proc/mount idea, and look for entries that look like they could be external storage volumes - fairly large and under a path of the form /mnt* or (for legacy) /sd* – Chris Stratton Aug 31 at 12:16.

Please check my question again. I wrote that Environment. GetExternalStorageDirectory() not necessarily returns the absolute path of the real external (sd card) directory.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
