How to persist webview cookies between app executions?

Question

It is possible to achieve this currently in Android? I only can find deprecated questions about old methods (CookieSynchManager) which not seems to work for this actually.

It is possible to achieve it? I can't find anything also on the Android Developers' Guide.

Having the same problem...I solved reading the doc here:

https://developer.android.com/reference/android/webkit/CookieSyncManager

For future readers: to force the Cookie sync process you can manually call the flush() method of CookieManager

I personally put in webview the following code:

public class MyWebViewClient extends WebViewClient {

    public void onPageFinished(WebView view, String url) {
      CookieManager.getInstance().setAcceptCookie(true);
      CookieManager.getInstance().acceptCookie();
      CookieManager.getInstance().flush();
    }
}

After looking at numerous other answers that didn't work for me, this was the one that finally did. Thanks! — Chris, Feb 01 '23 at 22:23

Since CookieSynchManager is deprecated, CookieManager.getInstance() is the CookieManager instance for your entire application. Hence, you enable it by

CookieManager.getInstance().setAcceptCookie(true)

setAcceptCookie(boolean accept);

Sets whether the application's WebView instances should send and accept cookies.

Hi, but these cookies are stored on RAM or will persist? – NullPointerException Aug 18 '17 at 08:56
@NullPointerException It will persist unless the data/cache is cleared from App Info. Or in other case if we want to clear the cookies, we can clear it programatically. – Manoj Perumarath Aug 18 '17 at 09:15
@Manoj_Frekzz thank you but where can you find it? can't I find that description on the documentation – NullPointerException Aug 18 '17 at 11:10
