找不到我的原始文件夹（Android Studio）

Question

First of all, I'm a noob, I just started coding and I don't know much about it.

My problem is that I want to create a MediaPlayer that plays a sound I've placed in a raw folder inside the res folder in my project. But when I do

example = MediaPlayer.create(this, R.raw.myfile)

it doesn't locate the R.raw* path.

I can solve this by importing android.R in my class, but now it won't locate my classes.

This is when I try without importing android.R

And this when I import android.R

Also it won't locate my file inside the raw folder either way.

Pls help I can't get it to work:c

Try rebuilding your project.

To do that you can go on the Build > Rebuild Project.
