How to Request Privacy Privileges for Tizen Native Service Application

I am working on a Hybrid App (Web UI with Native Service) of API version 4.0 for my Gear S3 Frontier.

My Service App has the privilege of Sensor and Location in the manifest file. When I check the privileges in code, the results show that I need to get privilege from user, which is fine.

I've implemented it using the Privacy Privilege Manager but when I request for privilege using the ppm_request_permission method, it doesn't show any message asking for the permission, and so it doesn't go the ppm_request_response_cb method.

Here's the relevant code:

Response Handler Implementation:

void ppm_request_response_handler(ppm_call_cause_e cause, ppm_request_result_e result, const char *privilege, void *user_data)
{

    dlog_print(DLOG_DEBUG, TAG, "In the ppm_request_response_handler.");

    /*
     * The result of a response triggered by calling ppm_request_permission() is a valid value only if
     * the cause parameter is equal to PRIVACY_PRIVILEGE_MANAGER_CALL_CAUSE_ANSWER.
     */
    if(cause == PRIVACY_PRIVILEGE_MANAGER_CALL_CAUSE_ANSWER)
    {
        if(result == PRIVACY_PRIVILEGE_MANAGER_REQUEST_RESULT_ALLOW_FOREVER)
        {
            if(!strcmp(privilege, "http://tizen.org/privilege/location"))
            {
                bIsLocationPrivilegeGranted = true;
                dlog_print(DLOG_DEBUG, TAG, "Service Application has been granted the Location privilege.");
            }

            if(!strcmp(privilege, "http://tizen.org/privilege/healthinfo"))
            {
                bIsHealthInfoPrivilegeGranted = true;
                dlog_print(DLOG_DEBUG, TAG, "Service Application has been granted the Health Info privilege.");
            }
        }
        else
        {
            if(!strcmp(privilege, "http://tizen.org/privilege/location"))
            {
                dlog_print(DLOG_DEBUG, TAG, "Service Application is denied to access the Location.");
            }

            if(!strcmp(privilege, "http://tizen.org/privilege/healthinfo"))
            {
                dlog_print(DLOG_DEBUG, TAG, "Service Application is denied to access the Health Information.");
            }
        }
    }
    else
    {
        if(!strcmp(privilege, "http://tizen.org/privilege/location"))
        {
            dlog_print(DLOG_DEBUG, TAG, "Service Application did not get any response to access the Location.");
        }

        if(!strcmp(privilege, "http://tizen.org/privilege/healthinfo"))
        {
            dlog_print(DLOG_DEBUG, TAG, "Service Application did not get any response to access the Health Information.");
        }
    }
}

typedef void(* ppm_request_response)(ppm_call_cause_e cause, ppm_request_result_e result, const char *privilege, void *user_data);

Method Call to Request for Permission:

//Set the function pointer value
ppm_request_response ppm_request_response_cb = ppm_request_response_handler;

//Request the user for the permission
ppm_request_permission(requiredPrivileges[i], ppm_request_response_cb, NULL);

Expected Behavior:

Service App should show any message asking the user about the permission, the ppm_request_response_handler method should be invoked then to handle the response of the user.

For as dar as i am aware, the multi permission call is only available in Tizen 5+, so you need to ask each permission individually if you're using Tizen 4.0 API.
