### This file defines the rules for isolated apps. An "isolated
### app" is an APP with UID between AID_ISOLATED_START (99000)
### and AID_ISOLATED_END (99999).
###
### isolated_app includes all the appdomain rules, plus the
### additional following rules:
###

type isolated_app, domain, domain_deprecated;
app_domain(isolated_app)

# Access already open app data files received over Binder or local socket IPC.
allow isolated_app app_data_file:file { read write getattr lock };
