Автозапуск события при старте приложения

Как можно реализовать автозапуск метода при старте приложения? Мой метод срабатывающий по кнопке

public void OnClickId (View view)
    {
        tvs = tv.getText().toString();
        Zapros1 = new zapros3();
        Zapros1.start(tvs);

        try {
            Zapros1.join();
        } catch (InterruptedException ie)
        {
            Log.e("pass 0 ", ie.getMessage());
        }
        tv.setText(tvs);
        num.setText(nums);


    }

Но как сделать его автоматическим при запуске приложения? Ошибка возникающая при добавлении/вызове в OnCreate

Решил проблему убрав эти строки

 tv.setText(tvs);
 num.setText(nums);
