This piece of code is called twice, when fragment is visible to user, triggering a double request to the backend server, not know why. I would evitate to use as workaround a counter, stopping process on the second time.Somebody know how to trigger it once for time, when navigating?
@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
//super.setUserVisibleHint(isVisibleToUser);
if(isVisible()){
//Toast.makeText(getContext(), ((ActivityLogin) getActivity()).choiceButton, Toast.LENGTH_LONG).show();
counter++;
//if(counter > 1 ) return;
String ex = extractUni(getContext());
//CERCA I DATI
SharedPreferences preferences = this.getActivity().getSharedPreferences("pref", Context.MODE_PRIVATE);
String username = preferences.getString("username", "");
String password = preferences.getString("password", "");
// PRENDI I DATI
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("username", username));
nameValuePairs.add(new BasicNameValuePair("password", password));
String ch = ((ActivityLogin) getActivity()).choiceButton;
if (ch.equals("login")) {
//LOGIN
try {
Toast.makeText(getContext(), "counter"+counter, Toast.LENGTH_LONG).show();
URL address = new URL("https://api.xxx.it/" + ex + "/login/");
Toast.makeText(getContext(), address+" >> login",+Toast.LENGTH_SHORT).show();
URLDataReader pp = new URLDataReader(getContext(), this, nameValuePairs);
pp.execute(address);
} catch (MalformedURLException e) {
e.printStackTrace();
}
} else {
Toast.makeText(getContext(), "counter"+counter, Toast.LENGTH_LONG).show();
try {
URL address = new URL("https://api.xxx.it/" + ex + "/ping/");
Toast.makeText(getContext(), address+" >> ping",+Toast.LENGTH_SHORT).show();
URLDataReader pp = new URLDataReader(getContext(), this, nameValuePairs);
pp.execute(address);
} catch (MalformedURLException e) {
e.printStackTrace();
}
}
}
}
