Problem when trying to create button through "Rectangle" shape

[THIAGO PORTO]

Hi! I'm just started studying this area, because of that I have some doubts about some mistakes that prevent my beginning and learning.

.O primeiro e o que eu dá uma certa dor de cabeça é o seguinteTento criar um botão usando a forma "Retângulo", mas quando tento o aplicativo iniciar em "run" (Shift+F10), ele não começa, e a mensagem a seguir é exibida:

   "java.lang.NoClassDefFoundError: Failed resolution of: Ljava/awt/Rectangle;

        at br.com.tpagames.BotaoNext.<init>(BotaoNext.java:22)
        at br.com.tpagames.MainClass.create(MainClass.java:27)

 button class code:

"package br.com.tpagames;

import com.badlogic.gdx.graphics.Texture;

import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import java.awt.Rectangle;

public class BotaoNext {


public Rectangle botao_n;

public boolean pressionado = false;
private float fator_pressionado=1.1f;

private Texture textura_bn;

public BotaoNext(Texture textura_bn, int posx_btn, int posy_btn, int size_btn){
this.textura_bn =textura_bn;
botao_n = new Rectangle(posx_btn,posy_btn,size_btn,size_btn);

}


public void draw(SpriteBatch batch){
if (pressionado){
batch.draw(textura_bn, (float) (botao_n.x-((botao_n.getWidth())*(fator_pressionado-1))/2),
(float) (botao_n.y-((botao_n.getHeight())*(fator_pressionado-1))/2), (float) botao_n.getWidth(), (float) botao_n.getHeight());

}else {
batch.draw(textura_bn,botao_n.x,botao_n.y, (float) botao_n.getWidth(), (float) botao_n.getHeight()); //textura, posiçãoX, posiçãoY, larguraX, alturaY
}

}

public boolean verif(int x, int y){
if(botao_n.x<=x && botao_n.x + botao_n.width>=x &&
botao_n.y<=y && botao_n.y+botao_n.height>=y ){
pressionado=true;

}else {
pressionado=false;

}
return pressionado;
}

}

the main class code:

"package br.com.tpagames;

import static br.com.tpagames.Constantes.btn_size;
import static br.com.tpagames.Constantes.btn_x;
import static br.com.tpagames.Constantes.btn_y;
import static br.com.tpagames.Constantes.screeny;

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

public class MainClass extends ApplicationAdapter {

private SpriteBatch batch;
private Menu1 menu1;
private Menu2 menu2;
private BotaoNext botão_next;


@Override
public void create () {
batch = new SpriteBatch();
menu1 = new Menu1();
menu2 = new Menu2();
botão_next = new BotaoNext(new Texture("Menu/botao_next.png"), btn_x,btn_y,btn_size);
}

//private int estado_atual = 0;
public int menu_atual = 0;

@Override
public void render () {

batch.begin();
draw();
input();
if (menu_atual>=2){
menu_atual = 0;
}
batch.end();

}

public void draw(){

if (menu_atual == 0){
botão_next.draw(batch);
menu1.draw(batch);



}
if (menu_atual == 1){
menu2.draw(batch);

}

}

public void input(){
if (Gdx.input.justTouched()){

int x = Gdx.input.getX();
int Y = screeny-Gdx.input.getY();


/*menu_atual = menu_atual+1;
*/
if (menu_atual>=2){
menu_atual = 0;
}

}



}

@Override
public void dispose () {

}

}"

constant class code:

"package br.com.tpagames;

import com.badlogic.gdx.Gdx;

public class Constantes {
public static int screenx = Gdx.graphics.getWidth();
public static int screeny = Gdx.graphics.getHeight();

public static int btn_size= (int)(0.4*screenx);
public static int btn_x = (int)(0.3f)*screenx;
public static int btn_y = (int)(screeny - btn_size/4);

}"

If anyone can help me, I would really appreciate it!!! 

[enh]

Android doesn't include AWT. that's Sun's old desktop graphics stuff.

i think gdx does support Android, so i suspect you've accidentally downloaded the _desktop_ version of the library rather than the Android one...
