Я просмотрел вопросы для тех же ошибок, но я реализую все решения, указанные в ответах, но я получаю следующее сообщение об ошибке в моем LogCat:

В моем коде имеют следующее:
@SuppressLint({ "ValidFragment", "UseSparseArrays" })
public abstract class BaseActivity extends FragmentActivity {
//The class is static and public
public static class ProgressDialogFragment extends DialogFragment {
public ProgressDialogFragment() {} //Empty Constructor
}
}
Может кто-то, пожалуйста, помогите мне определить, в чем проблема?
Спасибо.
