getQueryString()

gives

cid=1&params=zDmrLGXJ1DboOuqBn2062Z%2BQmQ4w7ODNGAfZL4L8rpk%3D.

and

getParameter(PARAM_NAME)

gives 

zDmrLGXJ1DboOuqBn2062Z+QmQ4w7ODNGAfZL4L8rpk=

What happened with %3D. ?

I used URLEncoder.encode(url, "UTF-8") to create params.

%3D is the equal (=) sign you have at the end of the parameter string. It's the same with %2B which was replaced by its decoded value: plus (+) sign.

The URLEncoder coverts any special characters (@,=,+,etc.) so that it can be used as a url. getParameter() coverts the string back to what it was originally while getQueryString() returns the raw querystring.
