Method Detail

• isSupported

   final Boolean isSupported(String type)

  Whether type is a supported permission type at all.

• androidPermission

   final String androidPermission(String type, Integer sdkInt)

  The Android runtime permission string that MUST be granted for type, given sdkInt. Returns null for types that need no runtime permission on this API level:

  • att — no Android equivalent (auto-granted no-op).

  • notification below API 33 — auto-granted (POST_NOTIFICATIONS didn't exist).

  • unknown/unsupported types.

• notificationGrantedWithoutPrompt

   final Boolean notificationGrantedWithoutPrompt(Integer sdkInt)

  Notification auth is granted without a prompt below API 33 (no runtime permission existed).

• manifestGuardStatus

   final PermissionStatus manifestGuardStatus(String type, Integer sdkInt, Function1<String, Boolean> permissionDeclared)

  Pure guard decision. Returns PermissionStatus.UNAVAILABLE when the type is unsupported, or when it requires a runtime permission that is NOT declared in the host manifest. Returns null to mean "safe to proceed". Injectable permissionDeclared keeps this unit-testable.

• route

   final PermissionRouteDecision route(PermissionStatus status)

  Pure status → route mapping used by the pipeline. Extracted for OS-free unit testing.

• isBlockedAfterDenial

   final Boolean isBlockedAfterDenial(Boolean granted, Boolean shouldShowRationale)

  Sticky-denied detection is post-request only: checkSelfPermission == DENIED is identical for never-asked vs permanently-denied. After a launch returns denied, !shouldShowRationale means the OS won't prompt again → blocked (present the settings fallback). Pure + testable.
