i tried this code in android studio and it says “cannot resolve” next to a lot of lines.
```auto
package com.example.test;
public class Sketch extends PApplet {
// Sketch.java
package tutorials.androidstudio.fragmentsv4;
import processing.core.PApplet;
public class Sketch extends PApplet {
public void settings() {
size(600, 600);
}
public void setup() {
}
public void draw() {
if (mousePressed) {
ellipse(mouseX, mouseY, 50, 50);
}
}
}
}
```

The guide says it needs to be in the lib folder.

Not sure, I’ve only recently created my first empty activity in android studio. I haven’t even added the sketch files.

I followed the steps on the link, however 2 of my imports do not work.
```auto
import androidx.appcompat.app.AppCompatActivity;
import processing.android.CompatUtils;
```

so I figured out I was using the wrong jar. I used the one that i used to build libraries and its slightly different. However now I get an error for `onRequestPermission`
and an error for the fragment activity
```auto
fragment.setView(frame, this);
```
despite both of these error the procject builds fine
