GCM IntentService

Question

我用這個代碼GCM，但是當我pushnotification，我得到的錯誤是這樣的：

這裏是我的代碼：

/** 
* Method called on device un registred 
*/ 
@Override 
protected void onUnregistered(Context context, String registrationId) { 
    Log.i(TAG, "GCM Device unregistered"); 
    generateNotification(context, "Device Unregistered", new Intent()); 
    ServerUtilities.unregister(context, registrationId); 
} 

/** 
* Method called on Receiving a new message 
*/ 
@Override 
protected void onMessage(final Context context, Intent intent) { 
    Log.i(TAG, "GCM Received message"); 
    if (intent == null) { 

    } else { 
    String message = intent.getExtras().getString("message"); 
    String namaPelanggan = "", alamat = "", telepon = "", noGangguan = ""; 
    // {

      telepon = json.getString("telepon"); 
      noGangguan = json.getString("reportNumber");

唯一的例外是不是GCM，這是因爲您嘗試在意向服務中更新您的UI，意圖服務實際上在單獨的線程中運行。 Android不允許在非主線程中更新UI。

嘗試移動您的更新UI代碼到主線程，這裏只是舉個例子：

new Handler(getMainLooper()).post(new Runnable() { 
     @Override 
     public void run() { 
      // put your update UI code here. 
     } 
    });
