To synchronize the Activity lifecycle with the Presenter logic in MVP architecture, the following is usually done:

  • Override the lifecycle methods in Activity (onCreate, onStart, onResume, onPause, onStop, onDestroy).
  • Call the corresponding Presenter methods within these methods, for example, presenter.onStart(), presenter.onStop(), etc.
  • The Presenter implements the logic that should be executed when the Activity's state changes.

Example:

public class MainActivity extends AppCompatActivity {
    private MainPresenter presenter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        presenter = new MainPresenter(this);
        presenter.onCreate();
    }

    @Override
    protected void onStart() {
        super.onStart();
        presenter.onStart();
    }

    @Override
    protected void onStop() {
        presenter.onStop();
        super.onStop();
    }

    @Override
    protected void onDestroy() {
        presenter.onDestroy();
        super.onDestroy();
    }
}

Thus, the Presenter receives notifications about the Activity's lifecycle and can manage its logic accordingly.
