The problem is in new ArrayAdapter<String> (this, android.R.layout.simple_list_item_1, android.R.id.text1, a); you must load context from Activity, but if you write this in onPostExecute it is another. Make in you Activity class some variable

Context context = MyActivity.this;

if your AsyncTask is in another class - create constructor and pass context from Activiy in it. and then you can do

 (context, android.R.layout.simple_list_item_1, android.R.id.text1, a);`
