ButtonSprite Shinning when I put two ITextureRegion

[brunogabriel]

Hello, I'm trying to use 2 ITextureRegion's in My ButtonSprite, but when I use two, the screen maintain shinning. If I put one ITextureRegion (I tested with two and single works normally), the screen don't shinning.

My code example:

import java.io.IOException;
import java.io.InputStream;

import org.andengine.engine.camera.Camera;
import org.andengine.engine.options.EngineOptions;
import org.andengine.engine.options.ScreenOrientation;
import org.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;
import org.andengine.entity.scene.Scene;
import org.andengine.entity.sprite.ButtonSprite;
import org.andengine.opengl.texture.ITexture;
import org.andengine.opengl.texture.bitmap.BitmapTexture;
import org.andengine.opengl.texture.region.ITextureRegion;
import org.andengine.opengl.texture.region.TextureRegionFactory;
import org.andengine.ui.activity.SimpleBaseGameActivity;
import org.andengine.util.adt.io.in.IInputStreamOpener;

import android.util.Log;

public class MainActivity extends SimpleBaseGameActivity {

private static int CAMERA_WIDTH = 800;
private static int CAMERA_HEIGHT = 480;
ITextureRegion background1;
ITextureRegion background2;

@Override
public EngineOptions onCreateEngineOptions() {
    final Camera camera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);
    return new EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED,
            new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), camera);
}

@Override
protected void onCreateResources() {

    try {
        ITexture bg = new BitmapTexture(getTextureManager(),
                new IInputStreamOpener() {
                    @Override
                    public InputStream open() throws IOException {
                        return getAssets().open("gfx/spr/jogo01.png");
                    }
                });

        ITexture bg2 = new BitmapTexture(getTextureManager(),
                new IInputStreamOpener() {
                    @Override
                    public InputStream open() throws IOException {
                        return getAssets().open("gfx/spr/jogo02.png");
                    }
                });
        bg.load();
        bg2.load();
        background1 = TextureRegionFactory.extractFromTexture(bg);
        background2 = TextureRegionFactory.extractFromTexture(bg2);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

@Override
protected Scene onCreateScene() {
    final Scene scene = new Scene();
    ButtonSprite buttonSprite = new ButtonSprite(0, 0, background1, background2,
            getVertexBufferObjectManager());
    Log.v("Hello:", "" + buttonSprite.getCurrentTileIndex());
    scene.registerTouchArea(buttonSprite);
    scene.attachChild(buttonSprite);
    buttonSprite.setCurrentTileIndex(0);

    return scene;
}

}
