public class AppDataUsageFragment extends Fragment{
    Spinner spinner;
    String[] date_array = new String[]{"Day","Week","Month","Year","Custom"};
    public AppDataUsageFragment() {
        // Required empty public constructor
    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

To avoid calling spinner.setOnItemSelectedListener() during initialization

spinner.setSelection(Adapter.NO_SELECTION, true); //Add this line before setting listener
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {

    }
});
