Question: After update I found that `getLoaderManager` is deprecated but I can't find that should I use instead of.  

How to get `LoaderManager`? Or what should I use instead of `Loader`s?

Answer: 
Loaders have been deprecated as of Android P (API 28). The recommended option for dealing with loading data while handling the Activity and Fragment lifecycles is to use a combination of ViewModels and LiveData.ViewModels survive configuration changes like Loaders but with less boilerplate. LiveData provides a lifecycle-aware way of loading data that you can reuse in multiple ViewModels.
The deprecated `getLoaderManager` has been replaced with `getSupportLoaderManager`. Try:

```
getSupportLoaderManager().initLoader(LOADER_NOTES, null, this); 

```

Works for me in API 28.
