    loginButton.setReadPermissions(Arrays.asList("email", "user_photos", "public_profile", "user_friends"));

    callbackManager= CallbackManager.Factory.create();
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(
                                JSONObject object,
                                GraphResponse response) {
                            // Application code
                            Log.e("LoginActivity", response.toString() + "    " + object.toString());

                            try {
                                String name=object.getString("name");
                                String email=object.getString("email");
                                String id=object.getString("id");
                                String gender=object.getString("gender");




                                Log.e("LoginActivity", name + "    " + email + "   " + id + "   " + gender);
                            } catch (JSONException e) {
                                e.printStackTrace();

                        }
                    });



            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender, birthday");
            request.setParameters(parameters);
            request.executeAsync();

        }

        @Override
        public void onCancel() {
            // App code
            Log.e("LOGIN Cancle", "LOGIN Cancle");
        }

        @Override
        public void onError(FacebookException exception) {
            // App code
            Log.e("LOGIN Cancle", exception.getMessage());
        }
    });

Starting with Graph API v2.4, you need to specifiy each field which you want to have returned in your query.

new GraphRequest(AccessToken.getCurrentAccessToken(),
  "/me", null , HttpMethod.GET,
  new GraphRequest.Callback() {
    ...

needs to become

new GraphRequest(AccessToken.getCurrentAccessToken(),
  "/me?fields=id,name,email", null , HttpMethod.GET,
  new GraphRequest.Callback() {
    ...

This is very well documented, and there are dozens of similar questions here on SO. Please refer to the docs first before posting a question.

Keep in mind that you need the appropriate permissions to be able to request user details. In this case it's email

LoginManager.getInstance().logInWithReadPermissions(WelcomeActivity1.this, (Arrays.asList("public_profile", "user_friends","user_birthday","user_about_me","email")));

String email;


LoginManager.getInstance().registerCallback(callbackManager,new FacebookCallback<LoginResult>() {
 @Override
  public void onSuccess(LoginResult loginResult) {
  Log.d("tag","FF fb onSuccess");
  GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(),new GraphRequest.GraphJSONObjectCallback() {
    @Override
    public void onCompleted(JSONObject object,GraphResponse response) {
     try {
           String[] splited ;
           JSONObject obj =  object.getJSONObject("picture").getJSONObject("data");

                              if (object.has("email"))
                              {
                                 email =  object.getString("email");
                              }
                              else
                              {
                                  email = "";
                              }



                            } catch (JSONException e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                            }


                            }
                        });
                Bundle parameters = new Bundle();
                parameters.putString("fields", "id,name,link,birthday,picture,email,gender");
                request.setParameters(parameters);
                request.executeAsync();


            }

            @Override
            public void onCancel() {
                Log.d("tag","fb onCancel");
                 // App code
            }



@Override
            public void onError(FacebookException exception) {
                Log.d("tag","fb onError");
                 // App code   
            }
});
