Best approach of loading all text files from a folder on android?

I made a word game for android where a user has to guess a word from a category. The categories are stored as text files in a folder named Categories and read into a dictionary
(Where the filename is Key and each line of the file is an array element) by GameManager at Awake(). Worked great on PC but when built for android it did not work.

The reason I tried this approach is to allow my friend to just drag and drop categories she wants to add into the game.

Is there a way to achieve something similar on Android?

Android guy here.

The inability to read/write files on android is likely do to a permissions error. You’ll need to make sure the user accepts the read/write permission that is stated in the manifest. On That note, make sure the read/write permission exists in the manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

All that aside, I believe you are overcomplicating this. Why not just use PlayerPrefs? It’s built in and easy to work with.
