onResume for android annotations

I am using android annotations and have some code that I need to execute in the onResume() function in my activity.

Is it safe to just override the onResume function from the android annotation activity (ie with @EActivity)?

You can bind your custom class with lifecycle component of android. It holds life cycle information of android component so that your custom class observe lifecycle changes.

public class MyObserver implements LifecycleObserver {
    @OnLifecycleEvent(Lifecycle.Event.ON_RESUME)
    public void connectListener() {
        ...
    }

    @OnLifecycleEvent(Lifecycle.Event.ON_PAUSE)
    public void disconnectListener() {
        ...
    }
}

myLifecycleOwner.getLifecycle().addObserver(new MyObserver());

Yeah. Just call super.onResume() and then add your code.

I'd do it just like their on create example here: https://github.com/excilys/androidannotations/wiki/Enhance-activities

Yeah, you should use these lifecycle methods just like with plain Android activities. There is one thing though: injected Views are not yet available in your onCreate method, this is why @AfterViews exist:

@EActivity(R.layout.views_injected)
public class ViewsInjectedActivity extends Activity {

    @ViewById
    Button myButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // myButton is not yet available here
    }

    @AfterViews
    void setupViews() {
        // myButton is first available here
        myButton.setText("Hello");
    }

    @Override
    protected void onResume() {
        super.onResume();
        // just as usual
    }
}
