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

• The Web UI launches the Service.
• Native Service uses the Sensor and Location data.

My Service App has the privilege of Senor 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 perfectly 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 Behaviour:

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.
