Android – extracting cookies after login in webview

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);
}

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
}
