ListAppPermissionsTool
dumpsys package <pkg> parsed for the app's permissions. Read-only. Scans the requested permissions:, install permissions:, and runtime permissions: sections of the dumpsys output (see parseDumpsysPermissions) and merges them by name; it does NOT classify by protection level.
Privilege: requires a working ShellBackend.
Params: package_name (required).
On success the result map carries package_name, count, and permissions — a list of { name, granted, flags } maps.
