Android - extracting cookies after login in webview

It was a quite late , but it might help someone

you can get the cookie value using this

getCookie("http://www.example.com","cookieName");

Declare the function as

public String getCookie(String siteName,String cookieName){     
    String CookieValue = null;

    CookieManager cookieManager = CookieManager.getInstance();
    String cookies = cookieManager.getCookie(siteName);       
    String[] temp=cookies.split(";");
    for (String ar1 : temp ){
        if(ar1.contains(cookieName)){
            String[] temp1=ar1.split("=");
            CookieValue = temp1[1];
            break;
        }
    }              
    return CookieValue; 
}

This answer is derived from @vimal1083. It returns the values in a Map, and of course written in Kotlin.

fun getCookieMap(siteName: String): Map<String,String> {

    val manager = CookieManager.getInstance()
    val map = mutableMapOf<String,String>()

    manager.getCookie(siteName)?.let {cookies ->
        val typedArray = cookies.split(";".toRegex()).dropLastWhile { it.isEmpty() }.toTypedArray()
        for (element in typedArray) {
            val split = element.split("=".toRegex()).dropLastWhile { it.isEmpty() }.toTypedArray()

            if(split.size >= 2) {
                map[split[0]] = split[1]
            } else if(split.size == 1) {
                map[split[0]] = ""
            }
        }
    }

    return map
}

Check this link - Pass cookies from HttpURLConnection (java.net.CookieManager) to WebView (android.webkit.CookieManager)

If you want to get cookies from webview, you will have to use android.webkit.CookieManager, from any HttpUrlConnection, however, you can extract cookies useing java.net.CookieStore

You will need to parse the string where you are getting all the cookies.

You can extract all cookies current url by this way from webview as string:

@Override
public void onPageFinished(WebView view, String url){
    String cookies = CookieManager.getInstance().getCookie(url);
    Log.d(TAG, "All the cookies in a string:" + cookies);
}
