android - share session between two webviews? -

First of all, someone can please tell how CookieManager.getInstance () works ? How do I actually get a session from the webview? Let's say that I have this

  cookie sync manager. Credit instance (webpage.); Cookie Manager Cookie Manager = Cookie Manager. Guest Instance ();   
 Do I get a session from a class named  WebviewPage ? But if I named my actual  WebView  from  webview , how to get a  cookieManager  session to  webview  Could? Even if I have not talked about two  WebView ,  webview1  and  webview2 . How do I know which session was stored in  cookieManager  ??  
 My main question is ... I have two activities and a webview in every activity. How can I get a session from Activity A and how can I reach it on the webview in Activity B?  
 Thank you!   
 
 
 As far as I know, you do not need to set cookies for webview2. Webview2 will automatically use cookies from webview1.
