Hi Deepak
adb pull /sys/fs/selinux/policy
adb logcat -b all -d | audit2allow -p policy
it should output something like this
#============= bootanim ==============
allow bootanim rootfs:lnk_file getattr;
Now navigate to the sepolicy directory of your device's folder(TOP/device/your_device/sepolicy) and add the allow rule returned above, in the respective te file.
Here I add this (allow bootanim rootfs:lnk_file getattr; ) line to (bootanim.te) file.
Hope this helps.
Regards
