How To Secure A Cookie In Android?

I am using Android's CookieManager to set a cookie in webview which acutally contains user id. I want to make this cookie secure to avoid any impersonation attacks. How can i make

Solution 1:

Not sure what you are doing, but cookies are set at the server. Thus you cannot make it secure on your side only. If you want to make sure your cookie remains a secret, use HTTPS for all operations that involve that cookie, and have the server set the cookie 'secure' flag, so that it is only sent over HTTPS.

Solution 2:

You can also set cookie attributes while setting cookie

For example:

 CookieManager.getInstance().setCookie(url,"USERID=ADADASD; secure ");.
