Есть функция loadPresetClicked(View v) которая вызывалась по кнопке , нужно сделать чтобы вызов был без нажатия по кнопке то есть просто loadPresetClicked(). И когда так делаю вылетает NullPointerException.
Вот сама функция :

public void loadPresetClicked() {
String[] names = new String[10 + model.getPresets().size()];
for (int i = 0; i < 10; i++) {
names[i] = eqService.equalizer().getPresetName((short) i);
}
for (short i = 0; i < model.getPresets().size(); i++) {
names[i + 10] = model.getPresets().get(i).getName();
}
this.onSaveInstanceState(new Bundle());
