I need to make some async http requests and get data from json then parse it and fill the ListView with adapter (I've custom one). So my problem is that I do all requests I need in the onCreate method first time and everything works well! I mean that I do 3 requests and my ListView is fiiling with data from JSON of first request and of the third and then ListView has 2 rows with different data. But if I destroy my activity and open it again I've only 1 row in my ListView though Log.w shows me that all data has downloaded. Consider that I work with adapter incorrect but I have no ideas where it's wrong. Here is my code :
public class smActive extends Activity {
private static final String MY_SETTINGS = "my_settings";
final String token = "token";
public CustomListAdapter adapter;
String hasBeenShown;
boolean EmptyArray = false;
String url;
private ArrayList<BDItem> feedList = null;
private ListView feedListView = null;
protected void onCreate(Bundle sup) {
super.onCreate(sup);
setContentView(R.layout.request_activity);
SharedPreferences prefs = getSharedPreferences(MY_SETTINGS,
Context.MODE_PRIVATE);
hasBeenShown = prefs.getString(token, "null");
url = "http://api.check-host.ru/myauto/request/list/?token=" + hasBeenShown + "&type=2&status=1";
Log.w("urlOnCreate", url);
try {
new ActiveAccepted().getPublicTimeline("5");

What I exactly want: make some requests like "http://api.check-host.ru/myauto/request/list/?token=04cb3b78-4c95-11e4-9ba3-b5b879359f7c&type=2&status=1" and "http://api.check-host.ru/myauto/request/list/?token=04cb3b78-4c95-11e4-9ba3-b5b879359f7c&type=2&status=5", get data from each other and put it in the ListView. Than work with every row personally as I do in setOnItemClickListener method. - Update my ListView every 8 seconds (now it's not important).
