setting Cookies in WebView android

Question

I'm trying to set some cookies on my WebView to open a browser with the same session that I have on my app.

I read a lot of answers but they don't work for me. The only solution I've found is in the loadUrl, hardcode the cookie data in extraHeaders, but as expected this only works for this requests, and doesn't maintain the session.

The code that I have is:

CookieSyncManager cookieSyncManager = CookieSyncManager.createInstance(mWebView.getContext());
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);
cookieManager.removeSessionCookie();
cookieManager.setCookie("http://xx.xxx.example.com","mid="+MySession.GetSession().sessionId+" ; Domain=.example.com");
cookieSyncManager.sync();

String cookie = cookieManager.getCookie("http://xx.xxx.example.com");

Log.d(LOGTAG, "cookie ------>"+cookie);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new TuWebViewClient());
mWebView.loadUrl("http://xx.xx.example.com");

getCookie() returns the correct data, but when I read the cookies from the server, those are empty. What is wrong? Please advise. Thank you!!!

Answer 1

Solved!!!! the problem is with the webView, I dont know what happend, but If I create the

WebView webView = new WebView(Activity.this);

it works. If I read the webview from activity with findViewById() it doesn't work.

Also if you need to set a list of cookies that you received previously from a website. All you have to do is use a for-loop to go through and set all of them . It helped me to solve the situation

Answer 2

CookieSyncManager cookieSyncManager = CookieSyncManager.createInstance(mWebView.getContext());
...
cookieSyncManager.sync();

is the cause of problem. You should do like this:

CookieSyncManager.createInstance(mWebView.getContext());
...
CookieSyncManager.getInstance().sync();

And there will be no need to manually create WebView...
