Jeff Sharkey authoredRaw physical storage devices are mounted by vold under /mnt/media_rw and then wrapped in a FUSE daemon that presents them under /storage. Normal apps only have access through /storage, but platform apps (such as ExternalStorageProvider) often bypass the FUSE daemon for performance reasons. avc: denied { search } for pid=6411 comm="Binder_1" name="media_rw" dev="tmpfs" ino=6666 scontext=u:r:platform_app:s0:c512,c768 tcontext=u:object_r:mnt_media_rw_file:s0 tclass=dir avc: denied { write } for pid=3701 comm="Binder_2" name="PANO_20131016_162457.jpg" dev="sda1" ino=127 scontext=u:r:platform_app:s0:c522,c768 tcontext=u:object_r:vfat:s0 tclass=file Bug: 19993667 Change-Id: I66df236eade3ca25a10749dd43d173ff4628cfadJeff Sharkey authoredRaw physical storage devices are mounted by vold under /mnt/media_rw and then wrapped in a FUSE daemon that presents them under /storage.
