無法從意向

Question

我試圖從意向獲取額外獲得附加功能，但它會導致錯誤

我開始活動這樣

Intent facebookIntent = new Intent(this, FacebookSettings.class); 
      startActivityForResult(facebookIntent, 15); 

然後我做了什麼新活動和finaly結束活動這種方式

public void onClick(View v) { 
      //FBnames and FBIds are not null String arrays 
      Intent data = new Intent(); 
      data.putExtra(FB_NAMES, FBnames); 
      data.putExtra(FB_IDS, FBIds); 
      setResult(RESULT_OK, data); 
      finish(); 
    } 

我得到一個錯誤。在父活動中甚至沒有涉及到onActivityResult()。

您是否確實接受了您要發送給他們的課程的額外資訊？像這樣：

Bundle extras = getIntent().getExtras();
