android Facebook的SDK崩潰的應用程序？

我嘗試添加Facebook登錄我的申請，我也跟着每一件事情，在這個例子中android Facebook的SDK崩潰的應用程序？

https://developers.facebook.com/docs/android/login-with-facebook/

還我已經下載了SDK和所有的例子都做工精細，

但我的問題是當我嘗試每一件事情從示例項目複製到我的項目，我的應用程序崩潰，如果我加入FaceBook會議

Session session = Session.getActiveSession(); 

if (session == null) { 
    if (savedInstanceState != null) { 
     session = Session.restoreSession(this, null, statusCallback, savedInstanceState); 
    } 
    if (session == null) { 
     session = new Session(this); 
    } 
    Session.setActiveSession(session); 
    if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) { 
     session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback)); 
    } 
}

這是日誌：

添加在構建路徑Android的支持，v4.jar。 –

@Virag檢查我的答案我修正了這兩個文件是相同的，所以問題出在哪裏！ – Jack

是否將android-support-v4.jar添加到了您的項目中？ – user2689294
