add data files to apk

Hi, I making a 2d project for Android. I’m using files to save data I use in the game but when i make apk I’m not able to take these files into the final apk.
The files are being generated in Application.persistentDataPath when I ran the game using unity editor.
How I can get these files and add to apk file in order to be copied in Application.persistentDataPath when the application will be installed?

Hi, I use serialization to save & load scenes. Firstable these files were in persistentDataPath but now I leave inside ASSETS\RESOURCES folders using dataPath I think will be take. The problem is in Android I’m not able to retrieve that information. I’m going to try use the solution proporsal on
Load TextAsset for serialization. - Unity Answers. I will write if works or doesn’t work.
