copied!<p>I would like to suggest a completely different approach to your problem. Instead of copying cookies from one place to another (manual sync), let's make HttpURLConnection and WebViews use the <strong>same</strong> cookie storage.</p> <p>This completely eliminates the need for sync. Any cookie updated in any one of them, will be immediately and automatically reflected in the other.</p> <p>To do this, create your own implementation of java.net.CookieManager which forwards all requests to the WebViews' webkit android.webkit.CookieManager.</p> <p>Implementation:</p> <pre><code>import java.io.IOException; import java.net.CookieManager; import java.net.CookiePolicy; import java.net.CookieStore; import java.net.URI; import java.util.Arrays; import java.util.List; import java.util.Map; public class WebkitCookieManagerProxy extends CookieManager { private android.webkit.CookieManager webkitCookieManager; public WebkitCookieManagerProxy() { this(null, null); } WebkitCookieManagerProxy(CookieStore store, CookiePolicy cookiePolicy) { super(null, cookiePolicy); this.webkitCookieManager = android.webkit.CookieManager.getInstance(); } @Override public void put(URI uri, Map<String, List<String>> responseHeaders) throws IOException { // make sure our args are valid if ((uri == null) || (responseHeaders == null)) return; // save our url once String url = uri.toString(); // go over the headers for (String headerKey : responseHeaders.keySet()) { // ignore headers which aren't cookie related if ((headerKey == null) || !(headerKey.equalsIgnoreCase("Set-Cookie2") || headerKey.equalsIgnoreCase("Set-Cookie"))) continue; // process each of the headers for (String headerValue : responseHeaders.get(headerKey)) { this.webkitCookieManager.setCookie(url, headerValue); } } } @Override public Map<String, List<String>> get(URI uri, Map<String, List<String>> requestHeaders) throws IOException { // make sure our args are valid if ((uri == null) || (requestHeaders == null)) throw new IllegalArgumentException("Argument is null"); // save our url once String url = uri.toString(); // prepare our response Map<String, List<String>> res = new java.util.HashMap<String, List<String>>(); // get the cookie String cookie = this.webkitCookieManager.getCookie(url); // return it if (cookie != null) res.put("Cookie", Arrays.asList(cookie)); return res; } @Override public CookieStore getCookieStore() { // we don't want anyone to work with this cookie store directly throw new UnsupportedOperationException(); } } </code></pre> <p>and finally use it by doing this on your application initialization:</p> <pre><code>android.webkit.CookieSyncManager.createInstance(appContext); // unrelated, just make sure cookies are generally allowed android.webkit.CookieManager.getInstance().setAcceptCookie(true); // magic starts here WebkitCookieManagerProxy coreCookieManager = new WebkitCookieManagerProxy(null, java.net.CookiePolicy.ACCEPT_ALL); java.net.CookieHandler.setDefault(coreCookieManager); </code></pre>
