Is getResources().getIdentifier() method efficient enough to use it in a ListView?

Issue

Some information about the app:

The app contains a lots of images in drawable folder. The size of every image is between 1kb and 3kb. And I need to draw them into a ListView.

What I need to get:

I need store the identifier of the image (R.drawable.my_image) into database with some aditional user information.

The problem:

When I update the app (adding new image resources), the identifier may change. So, in database I will have an outdated identifier, which is linking to a non-existing resource.

I've thought to store the resource name in database instead of the resource identifier and them I will retrieve it by getResources().getIdentifier(String, String, String) method. But I don't know if this method is efficient enough to use it in a ListView. The documentation says Note: use of this function is discouraged. It is much more efficient to retrieve resources by identifier than by name.

Do you know any other solution?

Solution

Finally Im using getResources().getIdentifier() method to load images into list (with recyclerview). My list has about 20 images. The average size is also less than 3kb. I've tried the app in older devices (wich behavior can be affected by his CPU) and it worked fine. I know this method is not recomended, but can be a solution.
