Need help to fix my project.

I added some mp3 files to my raw folder. The folder already holds many .json files. The mp3 file names were wrongly structured, they had capitals letters. After adding the mp3 files, the files in the drawable folder become "Unresolved reference" resources. The R.string. resources also turn "Unresolved"

All the R.drawable.* and R.string.* in the MainActivity.kt are "Unresolved reference", but every other *.kt file the same drawables and strings are found successfully.

I do not know why the drawable and strings resources got damage anyway since I only touched the raw folder.

I have 100 or more drawables.

I removed the mp3 files but still the project can't see the drawables.

I "Invalidate Caches", "Clear Project" build, but still can't see the drawables.

I tried moving the files to drawable-v34 (my target sdk is 34 minimum 26), but still can't see the drawables.

I am using Android Studio Ladybug | 2024.2.1 Patch 2

What should I do? What information should I post here for you to help me?

I found the cause of the problem.

While adding the mp3 files I also added code to use the mp3's.

val soundEntry: Int = soundpool.load(context, R.raw.mp3file, 1)

That made the Android Studio to auto import android.R

I though of removing the question as this was my error, but decided to leave it for other naive programmers like me that will experience this error and not lost there mind.
