Sample app not working?

Question

Android

I found a code example here https://github.com/sgothel/jogl-demos/blob/master/... Threw it
into my project

package com.example.myapplication;

import androidx.appcompat.app.AppCompatActivity;

import com.jogamp.opengl.GLCapabilities;
import com.jogamp.opengl.GLProfile;

import jogamp.newt.driver.android.NewtBaseActivity;
import android.os.Bundle;

//import com.jogamp.newt.ScreenMode;
import com.jogamp.newt.event.MouseAdapter;
import com.jogamp.newt.event.MouseEvent;
//import com.jogamp.newt.event.ScreenModeListener;
import com.jogamp.newt.opengl.GLWindow;
import com.jogamp.opengl.util.Animator;

public class MainActivity extends NewtBaseActivity
{
static {
        System.loadLibrary("gluegen-rt");
    }
    @Override public void onCreate(
            final Bundle state)
    {
        super.onCreate(state);

        final GLCapabilities caps =
                new GLCapabilities(GLProfile.get(GLProfile.GLES2));
        final GLWindow gl_window = GLWindow.create(caps);
        gl_window.setFullscreen(true);

        this.setContentView(this.getWindow(), gl_window);

        gl_window.addMouseListener(new MouseAdapter() {
            @Override public void mousePressed(
                    final MouseEvent e)
            {
                /*
                if (e.getPressure() > 2f) { // show Keyboard
                    ((com.jogamp.newt.Window) e.getSource()).setKeyboardVisible(true);
                }
                */
            }
        });
/*
        final Example example = new Example();

        // demo.enableAndroidTrace(true);
        gl_window.addGLEventListener(example);
        gl_window.getScreen().addScreenModeListener(new ScreenModeListener() {
            @SuppressWarnings("unused") public void screenModeChangeNotify(
                    final ScreenMode sm)
            {
                // Nothing.
            }

            @SuppressWarnings("unused") public void screenModeChanged(
                    final ScreenMode sm,
                    final boolean success)
            {
                System.err.println("ScreenMode Changed: " + sm);
            }
        });
*/
        final Animator animator = new Animator(gl_window);
        this.setAnimator(animator);

        gl_window.setVisible(true);
        animator.setUpdateFPSFrames(60, System.err);
        animator.resetFPSCounter();
        gl_window.resetFPSCounter();
    }
}

Of course, not everything went well, apparently the version is different or maybe his project does not work.

It gives such an error, that is, in fact, in the very first lines of the application where getGLProfile ()

The most annoying thing is that on the site of the library developer the same poor fellows like me ask, and they are answered with all sorts of nonsense, moreover, in English. And documentation like a brick and its properties, a shovel and concrete, and in what order to assemble it is not written

Answer 1

Come to terms with the idea that looking for code on the Internet is not a programmer.

Answer 2

JogAmp is the home of high performance Java™ libraries for 3D Graphics, Multimedia and Processing.
JOGL, JOCL and JOAL provide cross platform Java™ language bindings to the OpenGL®, OpenCL™, OpenAL and OpenMAX APIs.
tricky question .
Which of these do you think the android emulator supports?
Liba for using hardware buns.
