我最近升級了我的代碼以使用FB android SDK 3.0。我的應用程序有四個活動,不使用片段。奇怪的是我的代碼在android 2.3.4上沒有任何問題。但在Android 4.0.4中,會話狀態始終爲「開放」。我使用UiLifeCycleHelper,下面是啓動器活動中的代碼。Facebook android sdk 3.0登錄問題

SharedPreferences mPrefs; 
String access_token = mPrefs.getString("access_token", null); 

Session currentSession = Session.getActiveSession(); 
if(currentSession == null || currentSession.getState().isClosed()) 
{ 
    if(access_token!=null) 
    { 
     SharedPreferences.Editor editor = mPrefs.edit(); 

    //One time upgrade from FB SDK 2.0 to 3.0 
     editor.putString("access_token", null); 
     editor.commit(); 

     AccessToken new_access_token = AccessToken.createFromExistingAccessToken(access_token, null, null, null, null); 
     currentSession.open(new_access_token, myCallback); 
     Session.setActiveSession(currentSession); 
    } 
    else 
    { 
     Session.openActiveSession(this, true, myCallback); 
    } 
} 
else if (!currentSession.isOpened()) 
{ 
    OpenRequest openRequest = new OpenRequest(this).setCallback(myCallback); 
    openRequest.setDefaultAudience(SessionDefaultAudience.FRIENDS); 
    openRequest.setPermissions(Arrays.asList(permissions)); 
    openRequest.setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK); 
    currentSession.openForRead(openRequest); 

} 
else if(currentSession.isOpened()) 
{ 
    handleRequest(currentSession); 

} 


StatusCallback myCallback = new StatusCallback() 
{ 

    @Override 
    public void call(Session session, SessionState state, Exception exception) 
    { 
     handleRequest(session); 

    } 
}; 


public void handleRequest(Session activeSession) 
{ 

    Request new_request = new Request(activeSession, "/me/friends", null, null, new Callback() 
    { 

     @Override 
     public void onCompleted(Response response) 
     { 

      //Process the response and make UI changes. 
     } 

}); 
} 

首先,我懷疑問題是由於舊版本的Facebook應用程序(1.9)造成的。所以我升級到最新版本(3.2)。仍然問題仍然存在於Android 4.0.4上。

這是我在onActivityResult回調

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

代碼有什麼錯?

您是否記得添加onActivityResult的代碼?

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

也給看看this other question

請參閱我的編輯。我經歷了你提到的問題。我使用ListActivity而不是Activity。那是問題嗎? – 2013-05-13 06:01:58

我解決它自己。剛剛在myCallback中註釋掉了handleRequest。

StatusCallback myCallback = new StatusCallback() 
{ 

    @Override 
    public void call(Session session, SessionState state, Exception exception) 
    { 
    //handleRequest(session); 

    } 
}; 

這次我的應用在android 2.3.4和4.0.4上都沒有太大的問題。
