Just took me forever to get this straight, here is the trick on how to do it:
CookieSyncManager sym = CookieSyncManager.createInstance(appView.getContext()); CookieManager com = CookieManager.getInstance(); sym.sync(); String cookie = com.getCookie("file:///android_asset"); if (cookie == null) Log.d("MainActivity", "Cookie is null"); else{ Log.d("MainActivity", "Cookie exists, value is:"); Log.d("MainActivity", cookie); }
