Items On Listview In Widget Doesn't Display [android]

I create a ListView in my widget and getting the result from a web service. I don't have any problem in getting the result from the web service but the result is not displaying on

Solution 1:

did you added adapter.notifyDataSetChanged()?

Solution 2:

I solve this by following the answer here I found out that my getCount always returns 0 and therefore instead of using AsyncTask I put my web service call in onDataSetChanged().
