Is it run in Android Studio?

[ghost]

I entered the code into the Android studio as follows, but an error occurs at runtime.
Is there anything wrong with me?

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import java.util.ArrayList;
import fontastic.FGlyph;
import fontastic.Fontastic;
import processing.core.PApplet;
import processing.core.PVector;

public class MainActivity extends AppCompatActivity{

private PApplet myParent;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);



    Fontastic f = new Fontastic(myParent,"a");

    f.setAuthor("test");
    PVector[] points = new PVector[4];              // Define a PVector array containing the points of the shape
    points[0] = new PVector(0, 0);                  // Start at bottom left
    points[1] = new PVector(512, 0);        // The normal width is 512, the normal height 1024
    points[2] = new PVector(512, 1024); // y coordinates are from bottom to top!
    points[3] = new PVector(0, 1024);
    f.addGlyph('A').addContour(points);

    f.buildFont();
}
}

error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.fontastic/com.test.fontastic.MainActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String processing.core.PApplet.dataPath(java.lang.String)' on a null object reference
