尝试这样：下面的代码

if (Session.getActiveSession() != null) { 
    Session.getActiveSession().closeAndClearTokenInformation(); 
} 
Session.setActiveSession(null);

它不适用于第二项活动。 – Amardeepvijay

你在第二次活动中得到了什么错误..从我的理解你需要将facebook会话作为参数传递给下一个活动 –

如何将fb会话从一个活动传递给另一个活动？我正在使用sp和access_token。 – Amardeepvijay

使用。

FBLogout.setOnClickListener(new OnClickListener() { 
    @Override 
     public void onClick(View v) { 
      clearApplicationData(); 
      FBHandler.getInstance(this).facebookLogout(); 
     } 
}); 


public void clearApplicationData() { 
     File cache = getCacheDir(); 
     File appDir = new File(cache.getParent()); 
     if (appDir.exists()) { 
      String[] children = appDir.list(); 
      for (String s : children) { 
       if (!s.equals("lib") && !s.equals("files")) { 
        deleteDir(new File(appDir, s)); 
        Log.i("TAG", 
          "**************** File /data/data/APP_PACKAGE/" + s 
            + " DELETED *******************"); 
       } 
      } 
     } 
    } 

    public static boolean deleteDir(File dir) { 
     if (dir != null && dir.isDirectory()) { 
      String[] children = dir.list(); 
      for (int i = 0; i < children.length; i++) { 
       boolean success = deleteDir(new File(dir, children[i])); 
       if (!success) { 
        return false;

尝试这样做它为我工作。从Facebook //注销

public static void logoutFromFB(Context context) { 
    Session session = Session.getActiveSession(); 
    if (session != null) { 
     if (!session.isClosed()) { 
      session.closeAndClearTokenInformation(); 
      // clear your preferences if saved 
     } 
    } else { 
     session = new Session(context); 
     Session.setActiveSession(session); 
     session.closeAndClearTokenInformation(); 
     // clear your preferences if saved 
    } 
}

把这个FacebookSdk.sdkInitialize（getApplicationContext（））;然后在按钮单击事件上写下面的代码：

LoginManager.getInstance（）。logOut（）;

适合我。
