Tizen native web view: How to store and restore cookies in a native web view? - webview

Question

I am trying to develop a native web view app and it is working good.
But every time I close and restart the app all login/cookie information is lost.
How can I store and restore cookies in a native web view?
What is very weird: The HTML5 Web Storage (local db) gets restored, but the cookies aren't available anymore!?
Do you have any information for me?
Here is the basic code that I am using (from a Samsung example):
#include "webviewexample.h"
// Header files needed for EWK Webkit
#include <Ecore.h>
#include <Ecore_Evas.h>
#include <Ecore_Getopt.h>

#include <Evas.h>
#include <EWebKit.h>
#include <app.h>

Answer 1

You may Checkout the EWebKit: WebView API References for API functions related to Cookies.
relevant terms/functions on API references:
Ewk Cookie Manager,
Ewk_Cookie_Persistent_Storage,
ewk_cookie_manager_persistent_storage_set (),
Ewk_Cookie_Accept_Policy

Answer 2

Thank you for the answer, but I have not been able to solve it.
I have now solved it via a workaround:
1. via Javascript I save the cookies in the LocalStorage.
2. when starting the app I read the data from the LocalStorage and create the cookies again.
That's how it works for me.
