找不到處理意圖錯誤的活動

運行我的應用程序時，LogCat中出現以下錯誤。按下按鈕3（callButton）時發生錯誤。這會嘗試調出要聯繫的聯繫人列表。它什麼都不做，並在幾次按下後，應用程序崩潰。找不到處理意圖錯誤的活動

這是代碼。我明白這是相當混亂，我跟隨一個初學者的Android開發。

我有同樣的問題。當我宣佈這樣的意圖：

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); 
startActivityForResult(intent, PICK_CONTACT_REQUEST);

問題解決了
