我正在为我的 Samsung Galaxy Active Watch 开发 API 版本 5.5 的 Hybrid App（具有本机服务的 Web UI）。我想从另一个本地服务启动一个本地服务。
问题：
My Service App 在清单文件中拥有 http://tizen.org/privilege/appmanager.launch & http://tizen.org/privilege/application.launch 权限。当我使用 ppm_check_permissions 的 Privacy Privilege Manager 方法检查权限时，结果显示 http://tizen.org/privilege/application.launch 被用户永久拒绝。
我从不否认这个特权。我也重置了设备，但结果是一样的。当我尝试使用 ppm_request_permission 强制请求权限时，结果为 PRIVACY_PRIVILEGE_MANAGER_REQUEST_RESULT_DENY_FOREVER。
如果我尝试在没有权限的情况下启动目标应用程序，则不会按照要求启动。即使目标应用程序在同一个包中，我也会收到 APP_CONTROL_ERROR_LAUNCH_REJECTED 错误。
预期行为：
服务应用程序应该允许我向用户请求 http://tizen.org/privilege/application.launch 的权限，以便我可以从这个服务启动另一个服务。
