As per documentation, we don't have a method for removing individual cookies. But we could use an interesting work around with setCookie() to clear a site's cookies. as,

public abstract 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 will be ignored if it is expired.

So, the solution is, As mentioned in this answer, we need to manually clean up each cookie for each host key. eg:- facebook

android.webkit.CookieManager.getInstance().setCookie(".facebook.com", "locale="); android.webkit.CookieManager.getInstance().setCookie(".facebook.com", "datr="); android.webkit.CookieManager.getInstance().setCookie(".facebook.com", "s="); android.webkit.CookieManager.getInstance().setCookie(".facebook.com", "csm="); android.webkit.CookieManager.getInstance().setCookie(".facebook.com", "fr="); android.webkit.CookieManager.getInstance().setCookie(".facebook.com", "lu="); android.webkit.CookieManager.getInstance().setCookie(".facebook.com", "c_user="); android.webkit.CookieManager.getInstance().setCookie(".facebook.com", "xs=");

First of all I can suggest you to have a look at CookieManager class which manages the cookies used by WebView. There was a method removeAllCookie() for clearing the cookies but It was deprecated in API level 21, So instead of this you can use removeAllCookeis(callback) method. You can pass null as the callback if you don't need to know when the operation completes or whether any cookie were removed, and in this case it is safe to call the method from a thread without a Looper.

To clear cookies in lollipop or more you can use

CookieManager.getInstance().removeAllCookies(null); CookieManager.getInstance().flush(); 

and in rest

CookieSyncManager cookieSyncMngr=CookieSyncManager.createInstance(context); cookieSyncMngr.startSync(); CookieManager cookieManager=CookieManager.getInstance(); cookieManager.removeAllCookie(); cookieManager.removeSessionCookie(); cookieSyncMngr.stopSync(); cookieSyncMngr.sync();
