Add the user_birthday parameter in your logInWithReadPermissions() method

 LoginManager.getInstance().logInWithReadPermissions(MyProfil‌​eActivity.this, Collections.singletonList("public_profile", "email", "user_birthday", "user_friends"));

OR

loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions(Arrays.asList(
                "public_profile", "email", "user_birthday", "user_friends"));
