How to dev/test android app with Facebook sdk – while my app is not completed and not ready for review? – Facebook api

I’m developing android app which integrates Facebook SDK.
I need to login – OK, done this.
I need to retrieve friends birthdays – I know it is restricted. But can it be allowed after app review?

Or how to retrieve my friends list and birthday of each friend?

Thank you.

EDIT:
It looks strange to me that when using Facebook Graph API Explorer I do friend list request (e.g. graph.facebook.com/1012984682046884/friends) I’m getting full list of my friends. But when I do the same request from android application (see code below), I’m getting result:
onCompleted resp[{“summary”:{“total_count”:228},”data”:[]}]
Here is list of permission I’m requesting during login:
loginButton.setReadPermissions(Arrays.asList(“public_profile”, “email”, “user_birthday”, “user_friends”));
Also, have to tell that I am admin of my FB app, I use the same FB login.

    GraphRequest request = GraphRequest.newGraphPathRequest(
            act,
            fbuid+"/friends",
            new GraphRequest.Callback() {
                @Override
                public void onCompleted(GraphResponse response) {
                    // Insert your code here
                    Log.d("12x17","onCompleted resp["+response.getRawResponse()+"]");
                }
            });

    request.executeAsync();
