All,

When I take the screen snapshot by pressing  power button and volume down 
button. The image is not save correctly because

audit(1394045168.562:4): avc:  denied  { write } for  pid=6267 
comm=4173796E635461736B202331 
path="/storage/sdcard0/Pictures/Screenshots/Screenshot_2014-03-05-13-46-08.png" 
dev=fuse ino=1080366384 scontext=u:r:system_app:s0 
tcontext=u:object_r:sdcard_internal:s0 tclass=file

I only see the rule to grant system_app for sdcard_type:dir, but not file, in 
system_app.te


# Settings app reads sdcard for storage stats

allow system_app sdcard_type:dir r_dir_perms;

It seems we need to add
Allow system_app sdcard_type:file create_file_perms

Not sure why I don’t see the audit message for create operation. We do have 
these rules for platform_app though

platform_app.te:allow platformappdomain sdcard_type:dir create_dir_perms;

platform_app.te:allow platformappdomain sdcard_type:file create_file_perms;


Thanks,
Tai
