Android CookieManager setCookie creates multiple cookies

In my android application I have a webview. It loads URLs from multiple domains. I need to delete all cookies from a specific domain. I want to keep cookies from other domains. But I need to delete all cookies from one domain. I'm open to all other solutions that handles my request. (note that domain uses both http and https) But when I try to use CookieManager.setCookie, all available cookies for that domain didn't deleted. Multiple cookie keys appeear when I try to write to that keys. I attach my code below. You can find results in comment lines. At the end of story I get this cookie. Note for multiple values: ``` "userid=12%34; token=12ased; remember_check=0; userid='-1'; token='-1'; remember_check='-1';" ``` My helper function that splits cookie string to get cookie keys: ``` public static Vector<String> getCookieAllKeysByCookieString(String pCookies) { if (TextUtils.isEmpty(pCookies)) { return null; } String[] cookieField = pCookies.split(";"); int len = cookieField.length; for (int i = 0; i < len; i++) { cookieField[i] = cookieField[i].trim(); } Vector<String> allCookieField = new Vector<String>(); for (int i = 0; i < len; i++) { if (TextUtils.isEmpty(cookieField[i])) { continue; } if (!cookieField[i].contains("=")) { continue; } String[] singleCookieField = cookieField[i].split("="); allCookieField.add(singleCookieField[0]); } if (allCookieField.isEmpty()) { return null; } return allCookieField; } ``` I get present cookies: ``` // I take cookie string for specific URL mCookieManager = CookieManager.getInstance(); String url2="https://mysite.com"; String cookieString = mCookieManager.getCookie(url2); Toast.makeText(mContext, "cookie string:\n"+cookieString, Toast.LENGTH_SHORT).show(); // result is: userid=12%34; token=12ased; remember_check=0; ``` Then I call to replace old cookies. ``` Vector<String> cookie = CookieUtil.getCookieAllKeysByCookieString(cookieString); if (cookie == null || cookie.isEmpty()) { Toast.makeText(mContext, "cookie null", Toast.LENGTH_SHORT).show(); } if (cookie != null) { int len = cookie.size(); Toast.makeText(mContext, "cookie number: "+len, Toast.LENGTH_SHORT).show(); // result is, cookie number: 3 String cookieNames=""; for (int i = 0; i < len; i++) { cookieNames += "\n"+cookie.get(i) ; mCookieManager.setCookie(url2, cookie.get(i) + "='-1';"); } Toast.makeText(mContext, "cookieNames:\n"+cookieNames, Toast.LENGTH_SHORT).show(); // result is: "cookienames: userid token remember_check" mCookieSyncManager.sync(); cookieString = mCookieManager.getCookie(url2); Toast.makeText(mContext, "cookie string:\n"+cookieString, Toast.LENGTH_SHORT).show(); mCookieSyncManager.sync(); // result is: "userid=12%34; token=12ased; remember_check=0; userid='-1'; token='-1'; remember_check='-1';" } ``` Edit: I also tried setCookie like this: ``` mCookieManager.setCookie(url2, cookie.get(i) + "=-1;"); mCookieManager.setCookie(url2, cookie.get(i) + "=-1"); ``` Edit2: setCookie's signature is like this: ``` /** * 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. * * @param url the URL for which the cookie is set * @param value the cookie as a string, using the format of the 'Set-Cookie' * HTTP response header */ public void setCookie(String url, String value) { throw new MustOverrideException(); } ``` Although I get same keys inside cookie string (`"userid=12%34; token=12ased; remember_check=0; userid='-1'; token='-1'; remember_check='-1';"`) will they have different host or path ?
