空點異常錯誤 - android.content.ContextWrapper.startService

嘗試運行應用程序時，我意外地收到了空點異常錯誤。它發生時我在「的iChat按鈕」，這將導致你到另一個網頁點擊：空點異常錯誤 - android.content.ContextWrapper.startService

     LocalBroadcastManager.getInstance(this).registerReceiver(receiver, new IntentFilter("com.dooba.beta.matchOptionActivity1")); 
    } 

    @Override 
    public void onResume() { 

     super.onResume(); 
    } 
}

我相信在這部分發現錯誤：

query.findInBackground(new FindCallback<ParseUser>() { 
        public void done(List<ParseUser> user, ParseException e) { 
          if (e == null) { 

           Intent intent = new Intent(getApplicationContext(), MessagingActivity1.class); 
           startService(serviceIntent); 
           intent.putExtra("RECIPIENT_ID", user.get(0).getObjectId()); 
           startActivity(intent); 
          } else { 
           Toast.makeText(getApplicationContext(), 
            "Error finding that user", 
             Toast.LENGTH_SHORT).show(); 
          } 
         } 
        }); 
       } 
    });

任何幫助將不勝感激。

我一直在努力解決它，真的很感謝支持。在此先感謝

我沒有看到你已經初始化serviceIntent，也許它是空的，那NPE的起源？ – marcinj 2014-10-09 18:00:27

我把私人的意圖serviceIntent; – John 2014-10-09 18:04:39

但您必須初始化它，而不僅僅是聲明 – Blackbelt 2014-10-09 18:05:29

的問題是在這裏

Intent intent = new Intent(getApplicationContext(), MessagingActivity1.class); 
startService(serviceIntent); 
intent.putExtra("RECIPIENT_ID", user.get(0).getObjectId()); 
startActivity(intent);

您試圖啓動一個服務，但你傳遞給方法的意圖是永遠不會初始化。

如果你想開始一個Service和Activity你必須創建兩個單獨Intent對象 - 一個被傳遞給startService方法，另一個用於startActivity。

Intent serviceIntent = new Intent(getApplicationContext(), YourServiceName.class); 
startService(serviceIntent); 

Intent activityIntent = new Intent(getApplicationContext(), MessagingActivity1.class); 
startActivity(activityIntent);

感謝您的建議，是否有可能幫助我？ – John 2014-10-09 20:34:40

當然可以！看看我更新的評論:) – 2014-10-10 08:00:06

但他傳遞serviceIntent startService，而不是意圖 – marcinj 2014-10-10 09:38:21
