Android 4.4 Kitkat and second external storage -

-

there has been written lot kitkat external sdcard write permission it's not clear me how works. unfortunately don't have kitkat device sdcard slot. question is, can write secondary external storage @ all? based on the docs.

apps must not allowed write secondary external storage devices, except in package-specific directories

if in understand it, if don't have permission can write app specific folder on primary external storage /sdcard/android/data/package/... , app specific folder on secondary external storage /extsdcard/android/data/package/...

and write_external_storage can write locations on primary external storage /sdcard/* can't write location on secondary external storage (except app specific folder)?

thanks answers!

your analysis correct, other assuming primary external storage /sdcard (the exact path varies device, os level, , user account android 4.2+ tablets).

here blog posts wrote on external storage , removable ("secondary external") storage.
