Android Facebook SDK 3.0會話狀態「開放」

我正在使用他們的文檔整合Facebook的登錄。我遇到了一個問題，當我點擊Facebook登錄插件的會話更改爲「開放」和應用程序崩潰Android Facebook SDK 3.0會話狀態「開放」

我對Facebook的按鈕佈局

<com.facebook.widget.LoginButton 
    android:id="@+id/authButton" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentBottom="true" 
    android:layout_centerHorizontal="true" 
    />

，這個片段

public class FacebookFragment extends Fragment { 
private static final String TAG = "FacebookFragment"; 
private UiLifecycleHelper uiHelper; 
private Session.StatusCallback callback = new Session.StatusCallback() { 
    @Override 
    public void call(final Session session, final SessionState state, final Exception exception) { 
     onSessionStateChange(session, state, exception); 
    } 
}; 

@Override 
public View onCreateView(LayoutInflater inflater, 
     ViewGroup container, 
     Bundle savedInstanceState) { 
    View view = inflater.inflate(R.layout.activity_main, container, false); 
    LoginButton authButton = (LoginButton) view.findViewById(R.id.authButton); 
    authButton.setFragment(this); 
    authButton.setReadPermissions(Arrays.asList("user_likes", "user_status")); 
    return view; 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    uiHelper = new UiLifecycleHelper(getActivity(), callback); 
    uiHelper.onCreate(savedInstanceState); 
} 

@Override 
public void onResume() { 
    super.onResume(); 
    Session session = Session.getActiveSession(); 
    if (session != null && 
      (session.isOpened() || session.isClosed())) { 
     onSessionStateChange(session, session.getState(), null); 
    } 

    uiHelper.onResume(); 
} 

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

@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); 
} 

private void onSessionStateChange(Session session, SessionState state, Exception exception) { 
    if (state.isOpened()) { 
     Log.i(TAG, "Logged in..."); 
    } else if (state.isClosed()) { 
     Log.i(TAG, "Logged out..."); 
    } 
    else 
     Log.i(TAG, session.toString()); 
}

}

在活動中，我已經實現了所需的onActivityResult並檢索片段

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    if(savedInstanceState == null) { 
      // Add the fragment on initial activity setup 
      mainFragment = new FacebookFragment(); 
      getSupportFragmentManager() 
      .beginTransaction() 
      .add(android.R.id.content, mainFragment) 
      .commit(); 
     } else { 
      // Or set the fragment from restored state info 
      mainFragment = (FacebookFragment) getSupportFragmentManager() 
      .findFragmentById(android.R.id.content); 
     } 
} 


    @Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data); 
}

我想也許問題出在密鑰哈希，但我完全遵循了方向，從張貼在這個問題Key hash for Android-Facebook app

如何去「打開」狀態的任何鉛的答案將是很大的讚賞

在onResume()添加session.addCallback(callback)：

super.onResume(); 
Session session = Session.getActiveSession(); 
session.addCallback(callback);

謝謝當我到達我的電腦時，我會給它一個 – Darussian 2013-05-07 14:41:53

我還沒有嘗試過，但回調的目的是什麼？ – Darussian 2013-05-07 16:51:51

回調函數是一個具有抽象方法（調用）的接口，每次會話更改狀態（打開，關閉，打開，...）時都會調用該方法。你已經在你的代碼中實現了Session.Callback（回調）。你需要它來檢查會話終於改變狀態時打開 – 2013-05-07 17:00:04

的問題是在其Android版本：clearTaskOnLaunch = 「true」，從而是幹什麼的活動g登錄facebook。 OnActivityResult無法被調用。當我以調試模式運行應用程序時，我能夠得到一個異常。

+10

在AndroidManifest中+1'android：noHistory =「true」'是我的理由。 – caw 2013-05-29 13:42:39
