Login to Android WebView using browser cookies

I'm using Java code on an Android app to login and I receive cookies after I successfully login (using Retrofit).
What I want to do is if the login is successful and I go to a different tab which has a WebView that I'm automatically logged in with my browser cookie. On iOS this works perfectly. On Android I think I have to change something in my code so I'm using the following code to set the cookies in my CookieManager:
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);
for(String cookie: response.headers().values("Set-Cookie")){
System.out.println("cookie = " + cookie);
cookieManager.setCookie(Constants.baseURL, cookie);
}
This works fine and if I reload the WebView it seems to have all the right cookies, why am I not logged in in the WebView and does this work in iOS? Do I need to add something else?

May be you have forgotten to use CookieSyncManager.createInstance(..)
And call sync on obtained instance

Where to find / browse cookies in app data folder?

I have my app ("myapp") with following example package signature: com.example.mycorp.myapp
I browsed via adb shell the app folder /data/data/com.example.mycorp.myapp/ to find any cookies - in vain.
Since I have WebView objects showing external links (html) and Google Login as an example, there should be some cookies created (at least iOS colleagues have there cookies on the same app for iOS).
So where are can I find any cookies regarding my own app?

Programmatically by means of CookieManager:
Memeber variable
private CookieManager cookieManager = null;
In a onCreate() or another constructor
cookieManager = new CookieManager();
cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
CookieHandler.setDefault(cookieManager);
A checkCookies() Method which can be triggered frequently
List<HttpCokie> cookies = cookieManager.getCookieStore().getCookies();
Now, iterate through cookies and print them out.

If you want to get the cookie value you can use this:
CookieManager.getInstance().getCookie("http://the.url.com")

Reading secure cookies in android WebView

I am working on a android web application and based on if a secure cookie exists I want to do something. Unfortunately when I use the following line of code I only get a list of unsecure cookies.
String cookies = cookieManager.getCookie(siteName)
Does anyone know how I can get a list of all secure cookies for a specific domain?

You can retrieve secure cookies by using a url that starts with "https://".
String cookies = cookieManager.getCookie("https://example.com");
Returns all cookies (including secure only ones). Logic for getting cookies can be read at: https://github.com/adobe/chromium/blob/master/net/cookies/cookie_monster.cc#L1780 .

To resolve the issue I added the following before I created the webView
CookieManager.setAcceptFileSchemeCookies(true);
see CookieManager.setAcceptFileSchemeCookies(boolean accept)

getting trouble to set cookie android.webkit.CookieManager

i have login to a site through WebView. then i have get cookie which is set by the webview at login time. then i have tried to set the cookie later. please see my code:
CookieSyncManager.createInstance(context);
CookieManager cookieManager = CookieManager.getInstance();
Log.e("checkPost 1", cookie);
cookieManager.setCookie("https://************", cookie);
Log.e("checkPost 2", cookieManager.getCookie("https://*************"));
CookieSyncManager.getInstance().sync();
Log.e("checkPost 3", cookieManager.getCookie("https://*************"));
in checkPost 1 printed cookie shows that it is fine. but in checkPost 2 and after sync() it by CookieSyncManager.getInstance().sync(); statement, the checkPost 3 shows that most of the cookie is vanished. what is the problem ? i need to set the cookie. but i could not find a way spending about 2 days.
Edit:
in android documentation it says that:
public void setCookie (String url, String value)
Sets a cookie for the given URL. Any existing cookie with the same
host, path and name will be replaced with the new cookie. The cookie
being set must not have expired and must not be a session cookie,
otherwise it will be ignored.
is there any way to force CookieManager set session cookie via setCookie() ?
i think the problem is, may be i am trying to set session cookie

i don't know there is any answer or not for my question. but for my purpose i have use another way to solve my problem. it's a long process, but it works. i have given up the idea to save session cookie in CookieManager (which is not possible by the document of Android Developer site). So, what i have done is: i have converted the session cookie in string and save them in memory. for later use i just take the string from memory and convert it back to session cookie.
Edit:
(For negative voters) I have told in my answer that the process is too long, like 4-5 classes. and this project was my first project in android so the codes are too messy. all the class is full of too much code. so it is impossible to post it here. i have told the process i have used. so why negative vote?
i have converted the session in my own way and build the string to session in reverse way.
if there is any way i would post the answer. it take me about 15~20 days to build the classes and algorithms. so why not you do some Google and find a better way, or just simply build your own algorithm and process like mine. i have told the key part here, you just need to find a way to implement it into code. Thanks

Android: Delete cookies in-app // How to get the browser context

I'm failing at the moment in letting my app delete the browser cookies or some specific cookies.
The way I found was to implement the following:
CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.removeAllCookie();
But nothing is happening. An with the method hasCookie() is get false as return. Is there no way for deleting a cookie from inside my app?
Thanks for your help!

You can use CookieSyncManager to delete cookies from your own WebView widget(s).
You cannot delete cookies from third-party applications that use WebView or other Web rendering engines.
