            ch.setChecked(apps.get(position).c1);

            return convertView;
        }


    };

you can add all the checked app names in a set and then save this set in sharedprefrences:-

Set<String> set =new HashSet<String>();
ch .setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean b) {
             if()
            {
             set.add(ch.getText());
            }
             else 
            {
            set.remove(ch.getText());
            }

        });

then in your sharedprefrences put the set using the editor

 editor.putStringSet("appnames",set);
