【问题描述】：

我允许在我的应用程序中登录 facebook，但是当我从 Facebook Login webview 中按 Ok 并且当我再次打开应用程序时我能够在我的屏幕上看到注销按钮时崩溃？？？

在 OnActivityResult 中出现错误，它在那里崩溃..

我把我的日志放在这里。

我的 LoginFragment.java

loginButton = (LoginButton) findViewById(R.id.login_button); loginButton.setFragment(this);

loginButton.setOnClickListener(new OnClickListener()

        @Override
        public void onClick(View v) 
            checkLoginwithFB();

        
    );

private void checkLoginwithFB() 

 LoginManager.getInstance().registerCallback(callbackManager,
                new FacebookCallback<LoginResult>() 
            public void onSuccess(LoginResult loginResult)
               
                LoginFragment.this.user = user;
                Profile profile = Profile.getCurrentProfile();
                RC_FB_SIGN_IN = loginButton.getRequestCode();
                Log.e("===FIrstname===>", "===FIrstname===>"+profile.getFirstName());
                if(profile !=null)
                    final String ID= profile.getId();
                    final String Name = profile.getName();

                    Log.e("===ID===>", "===ID===>"+profile.getId());
                    Log.e("===FIrstname===>","===FIrstname===>"+profile.getName());

                // It's possible that we were waiting for this.user to be
                // populated in order to post a
                // status update.
                //if (user != null) 

                    Log.e(TAG, ID);
                    Log.e(TAG,Name);
                     GraphRequest request = GraphRequest.newMeRequest(AccessToken.getCurrentAccessToken(), new GraphRequest.GraphJSONObjectCallback()

【问题讨论】：

显示LoginFragment

我可以放在这里吗？？？

把它作为问题的一部分:)

【参考方案1】：

我猜你忘了从你的活动的 onActivityResult() 调用 CallbackManager.onActivityResult()。参考https://developers.facebook.com/docs/facebook-login/android

【讨论】：

我已经将 CallbackManager.onActivityResult() 放入代码中，请检查。

而你的数据对象不为空？

是什么意思？我猜它是空的

根据您的日志消息，数据不为空。另一种猜测 - 您应该从片段 onActivityResult() 中调用 CallbackManager.onActivityResult()，而不是活动之一。
