Session.openActiveSession只要求在开幕Facebook的Andr​​oid SDK中 [英] Session.openActiveSession only calls OPENING in Facebook Android SDK

问题描述

我试图登录与Facebook使用Facebook的Andr​​oid SDK，但是状态回调与打开会话状态触发一次。在此之后，Facebook的登录活动似乎没有内容（我知道这是该活动，因为它有一个我为 title_facebook_login 设置在strings.xml中的标题）作一简要片刻，在一秒钟内消失。没有其他的回调被触发，没有例外，没有崩溃。它只是等待永远在我最初的活动。这是我的code：

I am trying to login with Facebook using the Facebook Android SDK, however, the status callback is fired only once with OPENING session state. After that, a Facebook login activity appears with no content (I know it's that activity as it has the title that I've set for title_facebook_login in strings.xml) for a brief moment and disappears within a second. No other callback is fired, no exceptions, no crashes. It just waits forever at my initial activity. Here is my code:

Session.openActiveSession(parent, true, new Session.StatusCallback() {
        @Override
        public void call(Session session, SessionState state, Exception exception) {
            if(state == SessionState.OPENED){
                String accessToken = session.getAccessToken();
            }
        }
    });

为什么不回调火 SessionState.OPENED （或创建的，甚至是封闭式的），但只打开了？

Why wouldn't the callback fire for SessionState.OPENED (or CREATED, or even CLOSED) but only OPENING?

推荐答案

您需要调用 onActivityResult

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        uiHelper.onActivityResult(requestCode, resultCode, data);
    }

所以，当登录完成。它涉及到同样的活动，并呼吁状态回调是会话状态打开

初​​始化 UiLifecycleHelper

private UiLifecycleHelper uiHelper;

在OnCreate中需要之前调用的setContentView

in oncreate need to call before setContentView

uiHelper = new UiLifecycleHelper(this, statusCallback);
        uiHelper.onCreate(savedInstanceState);

和需要保持会议

    @Override
    protected void onResume() {
        super.onResume();
        uiHelper.onResume();
    }

    @Override
    protected void onPause() {
        super.onPause();
        uiHelper.onPause();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        uiHelper.onDestroy();
    }
