Loading from Asset Folder?

I want to check if a certain model is in my assets folder through a code.
For example:
I want to load a model with the name of Anakin. I enter the word Anakin from my keyboard and my code should search from my assets folder if there is a model with the name of Anakin. If yes then load it. Is this possible? If Yes, Can you guide me through the code?

What about AssetManager.loadAsset()? If it returns null, the asset doesn’t exists.

Just keep a list.
