Subject: [PATCH] support new special runtime permissions
|
|
|
|
These are treated as a runtime permission even for legacy apps. They
|
|
need to be granted by default for all apps to maintain compatibility.
|
|
|
|
Ported from 10: 4d5d82f4e2fb9ff68158bf30f3944591bb74dd04
|
|
|
|
Changes from 10:
|
|
- It seems like parts of PackageManagerService#resetUserChangesToRuntimePermissionsAndFlagsLPw
|
|
were refactored into PermissionManagerService#resetRuntimePermissionsInternal.
|
|
As a result, PackageManagerService is no longer modified.
|
|
