libgdx, animatios dont scale on android - camera

Question

I was testing my app on android,
my app have 1 background image with 2 animations using TextureAtlas
it works fine on desctop, the sprite and the animations all scale but when I teste it on android, the sprite resize corretly but the animations dont resize at all
constantes.VIRTUAL_WIDTH=1920;
constantes.VIRTUAL_HEIGHT=1080;
.....
public static void show() {
camera = new OrthographicCamera(constantes.VIRTUAL_WIDTH, constantes.VIRTUAL_HEIGHT); //Aspect Ratio Maintenance
batch = new SpriteBatch();
texturafundo = new Texture("cenarios/penhasco.jpg");
spriteFundo = new Sprite(texturafundo);
spriteFundo.setSize(Gdx.graphics.getWidth(),Gdx.graphics.getHeight());
// animations
textureAtlas = new TextureAtlas(Gdx.files.internal("anima/rio.txt"));
animacao = new Animation(1/10f, textureAtlas.getRegions());
textureAtlas2 = new TextureAtlas(Gdx.files.internal("anima/portal.txt"));
animacao2 = new Animation(1/10f, textureAtlas2.getRegions());
}
public void render(float delta) {
// update camera
camera.update();
// set viewport
Gdx.gl.glViewport((int) viewport.x, (int) viewport.y,
(int) viewport.width, (int) viewport.height);
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
elapsedTime+=delta;
batch.begin();
spriteFundo.draw(batch);
//sesenha animacao 1
batch.draw(animacao.getKeyFrame(elapsedTime, true), 0, 0);
batch.draw(animacao2.getKeyFrame(elapsedTime, true), 788, 249);
batch.end();
}
public void resize(int width, int height) {
float aspectRatio = (float)width/(float)height;
float scale = 1f;
Vector2 crop = new Vector2(0f, 0f);
if(aspectRatio > constantes.ASPECT_RATIO) {
scale = (float) height / (float) constantes.VIRTUAL_HEIGHT;
crop.x = (width - constantes.VIRTUAL_WIDTH * scale) / 2f;
} else if(aspectRatio < constantes.ASPECT_RATIO) {
scale = (float) width / (float) constantes.VIRTUAL_WIDTH;
crop.y = (height - constantes.VIRTUAL_HEIGHT * scale) / 2f;
} else {
scale = (float) width / (float) constantes.VIRTUAL_WIDTH;
}
float w = (float) constantes.VIRTUAL_WIDTH * scale;
float h = (float) constantes.VIRTUAL_HEIGHT * scale;
viewport = new Rectangle(crop.x, crop.y, w, h);
}
