如何在android中构建一个好的组件(Dagger)监听器？

public interface ComponentListener {
    void onEvent();
}

@Component
public interface MyComponent {
    void inject(MainActivity activity);

    void triggerEvent();
}

public class MainActivity extends AppCompatActivity implements ComponentListener {
    @Inject
    MyComponent myComponent;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 初始化Dagger组件
        DaggerMyComponent.create().inject(this);
    }

    @Override
    public void onEvent() {
        // 处理事件
    }
}

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        // 注册监听器
        DaggerMyComponent.create().triggerEvent();
    }
}
