java.lang.RuntimeException：無法啓動接收器* .mycustomReceiver java.lang.NullPointerException

Question

我得到一個Java空指針異常無法啓動接收器錯誤。我正在從parse.com接收推送的應用程序，我正在錯誤的Android 4.0.3 - 4.0.4，並且還當我重新啓動一些設備..

我logcat的是

**java.lang.RuntimeException: Unable to start receiver com.omega.omegaplus.main.MyCustomReceiver: java.lang.NullPointerException

我的廣播接收器是

@Override 
    public void onReceive(Context context, Intent intent) { 

     Bundle extras = intent.getExtras();   
     String message = extras != null ? extras.getString("com.parse.Data") 
       : ""; 

     Log.e("message ", " " + message);   
     JSONObject jObject; 
     try { 
      jObject = new JSONObject(message); 
      //objectId = jObject.getString("id"); 
      time = jObject.getString("time"); 
      msg = jObject.getString("title"); 
      title = jObject.getString("msg"); 
       GCMMessage gcmMessage = new GCMMessage(); 

      //gcmMessage.setMsg_id(1); 
      gcmMessage.setMsg_body(msg); 
      gcmMessage.setMsg_title(title); 
      gcmMessage.setType(0); 
      gcmMessage.setDateTime(time); 

       DatabaseUtil.insertMessage(context, gcmMessage); 

     }   
     catch (JSONException e) { 
      e.printStackTrace(); 
     } 
} 

當我重新啓動我的手機，然後它也顯示同樣的錯誤......，否則是工作的罰款。

我會猜測，message有""值或NULL

JSONObject jObject; 
    try { 
     if (message != null && !message.equals("") { 
      jObject = new JSONObject(message); 
      //objectId = jObject.getString("id"); 
      time = jObject.getString("time"); 
      msg = jObject.getString("title"); 
      title = jObject.getString("msg"); 
      GCMMessage gcmMessage = new GCMMessage(); 

      //gcmMessage.setMsg_id(1); 
      gcmMessage.setMsg_body(msg); 
      gcmMessage.setMsg_title(title); 
      gcmMessage.setType(0); 
      gcmMessage.setDateTime(time); 

      DatabaseUtil.insertMessage(context, gcmMessage); 
     } 

     }   
     catch (JSONException e) { 
     e.printStackTrace(); 
     }
