OnCreate not called on Activity

Question

I've created AbstractActivity and an AbstractFormActivity to rid of some boilerplate code, their content may be irrelevant to the question, but I will post it anyway, maybe I misunterstood something so, there they are:

public abstract class AbstractActivity extends ActionBarActivity {

    protected ObjectGraph graph;

    @Inject
    public Bus bus;

    @Inject
    public App app;

    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
        setContentView(getLayout());
        setupInjection();
    }

    public void setupInjection() {
        graph = ((App) getApplication()).createScopedGraph(getModule());
        graph.inject(this);
        bus.register(this);
        ButterKnife.inject(this);
    }

    protected abstract Object getModule();
    protected abstract int getLayout();
}

and

public abstract class AbstractFormActivity<T extends EntidadeBase> extends AbstractActivity implements Form<T> {

    protected T entity;
    protected Map<View, Boolean> formValidations;
    protected AbstractFormActivity() {
       formValidations = new HashMap<View, Boolean>();
    }

    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
    }

    protected boolean passedValidations() {
        for (View key : formValidations.keySet()) {
            if (!formValidations.get(key)) {
                return false;
            }
        }
        return true;
    }

    protected void validateAndSolidify() {
        if (passedValidations()) {
            solidify();
        }
        entity = null;
    }

    @Override
    public void validateMoreComplexFields() {
    }
}

finally I've created an Implementation of those mother Activities:

public class MercadoriaFormActivity extends AbstractFormActivity<Mercadoria> {

...

   @Override
   public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
    }

...

}

My problem is that the onCreate method is not called.

Any help is highly appreciated.

onCreate() version you are currently using is added in Android 21. You should use version below instead:

protected void onCreate (Bundle savedInstanceState)

Helped a lot. Thank you for opening eyes :) I added onCreate in a fast manner and didn't notice I added the one from API 21. Thanks a lot! :) – Jack Lynx Jan 12 '17 at 20:34

I have also faced the same issue. After a couple of hours, I found my mistake, instead on (savedInstanceState: Bundle, persistentState: PersistableBundle) function has to override the below one.

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
}
