【问题描述】：

我在facebook developers 上查看了教程，它看起来与我在互联网上找到的不同。哪一种是实现facebook登录的最佳方式？还有，哪里有学习facebook sdk for android的好地方，好像官方的不完整？

Facebook.developer 使用 loginButton.setRegisterCallback();

@Override
public View onCreateView(
        LayoutInflater inflater,
        ViewGroup container,
        Bundle savedInstanceState) 
    View view = inflater.inflate(R.layout.splash, container, false);

    loginButton = (LoginButton) view.findViewById(R.id.login_button);
    loginButton.setReadPermissions("user_friends");
    // If using in a fragment
    loginButton.setFragment(this);    
    // Other app specific specialization

    // Callback registration
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() 
        @Override
        public void onSuccess(LoginResult loginResult) 
            // App code
        

        @Override
        public void onCancel() 
            // App code
        

        @Override
        public void onError(FacebookException exception) 
            // App code
        
    );    

programmerguru.com 使用 UiLifecycleHelper，我在官方网站上没有找到它

public class MainActivity extends ActionBarActivity 
    // Create, automatically open (if applicable), save, and restore the 
    // Active Session in a way that is similar to Android UI lifecycles. 
    private UiLifecycleHelper uiHelper;
    private View otherView;
    private static final String TAG = "MainActivity";
 
    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // Set View that should be visible after log-in invisible initially
        otherView = (View) findViewById(R.id.other_views);
        otherView.setVisibility(View.GONE);
        // To maintain FB Login session
        uiHelper = new UiLifecycleHelper(this, callback);
        uiHelper.onCreate(savedInstanceState);
    
     
    // Called when session changes
    private Session.StatusCallback callback = new Session.StatusCallback() 
        @Override
        public void call(Session session, SessionState state,
                Exception exception) 
            onSessionStateChange(session, state, exception);
        
    ;
     
    // When session is changed, this method is called from callback method
    private void onSessionStateChange(Session session, SessionState state,
            Exception exception) 
        final TextView name = (TextView) findViewById(R.id.name);
        final TextView gender = (TextView) findViewById(R.id.gender);
        final TextView location = (TextView) findViewById(R.id.location);
        // When Session is successfully opened (User logged-in)
        if (state.isOpened()) 
            Log.i(TAG, "Logged in...");
            // make request to the /me API to get Graph user
            Request.newMeRequest(session, new Request.GraphUserCallback() 
 
                // callback after Graph API response with user
                // object
                @Override
                public void onCompleted(GraphUser user, Response response) 
                    if (user != null) 
                        // Set view visibility to true
                        otherView.setVisibility(View.VISIBLE);
                        // Set User name 
                        name.setText("Hello " + user.getName());
                        // Set Gender
                        gender.setText("Your Gender: "
                                + user.getProperty("gender").toString());
                        location.setText("Your Current Location: "
                                + user.getLocation().getProperty("name")
                                        .toString());
                    
                
            ).executeAsync();
         else if (state.isClosed()) 
            Log.i(TAG, "Logged out...");
            otherView.setVisibility(View.GONE);
        
    
     
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) 
        super.onActivityResult(requestCode, resultCode, data);
 
        uiHelper.onActivityResult(requestCode, resultCode, data);
        Log.i(TAG, "OnActivityResult...");
    
     
    @Override
    public void onResume() 
        super.onResume();
        uiHelper.onResume();
    
 
    @Override
    public void onPause() 
        super.onPause();
        uiHelper.onPause();
    
 
    @Override
    public void onDestroy() 
        super.onDestroy();
        uiHelper.onDestroy();
    
 
    @Override
    public void onSaveInstanceState(Bundle outState) 
        super.onSaveInstanceState(outState);
        uiHelper.onSaveInstanceState(outState);
    

【问题讨论】：

使用官方教程。之所以不同，是因为 Facebook 刚刚发布了 SDK v4，让登录和分享变得更加容易。互联网上的许多其他教程仍然适用于 v3 甚至 v2 (gasp)，并且已经过时了。

感谢您的回答。它回答了我的问题。

【参考方案1】：

正如@Ming Li 所说，坚持the official tutorials。之所以有许多不同的教程，是因为 Facebook SDK 有许多不同的版本，每个版本可能都有不同的方式来处理 Facebook 的事情。如果他们想出一个更好的主意来用 Facebook 做事，他们就会改变它。
