Java – “unable to parse the symbol ‘request’ of Facebook graph API” error

I will the latest Facebook SDK 4.0 1 is included in the Android studio project I want to make the basic graph API calls listed on the graph API reference

/* make the API call */
new Request(
    session,"/me",null,HttpMethod.GET,new Request.Callback() {
        public void onCompleted(Response response) {
            /* handle the result */
        }
    }
).executeAsync();

But I can't import the request class. I received an error and couldn't resolve the symbolrequest "

How to solve this problem? Do I need to import other libraries to use the graph API?

thank you.

Solution

The request class has been renamed graphrequest
