final Database myDb = new Database(this);
		
		String url = "http://travelthailand.incasible.com/mobile_selectDB.php";
		
		try {
			
			JSONArray data = new JSONArray(getJSONUrl(url));
			
			final ArrayList<HashMap<String, String>> MyArrList = new ArrayList<HashMap<String, String>>();
			HashMap<String, String> map;
			
			for(int i = 0; i < data.length(); i++){
                JSONObject c = data.getJSONObject(i);
                
    			map = new HashMap<String, String>();
    			map.put("PoiID", c.getString("poi_id"));
    			map.put("PoiName", c.getString("poi_name"));
    			map.put("PoiDetail", c.getString("poi_detail"));
    			map.put("PoiLat", c.getString("poi_latitude"));
    			map.put("PoiLng", c.getString("poi_longitude"));
    		    MyArrList.add(map);
    		    
    		    long flg1 = myDb.InsertData(PoiID, PoiName, PoiDetail, PoiLat, PoiLng);
            	if(flg1 > 0)
            	{
            	 Toast.makeText(CreateDatabase.this,"Insert(1) Data Successfully",
            			 	Toast.LENGTH_LONG).show();
