i tried making an android app with andengine and i used eclipse for it ,but when i run it, it shows the message "unfortunately,app has stopped". what is the reason? here is the java code:

package your.packhage.namespace;
import java.io.IOException;
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.Sprite;
import org.andengine.entity.util.FPSLogger;
import org.andengine.opengl.texture.ITexture;
import org.andengine.opengl.texture.bitmap.AssetBitmapTexture;
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.color.Color;

public class GgActivity extends SimpleBaseGameActivity {

private static final int CAMERA_WIDTH = 800;
private static final int CAMERA_HEIGHT = 480;
private ITexture mHelloWorldTexture;
private ITextureRegion mHelloWorldTextureRegion;
@Override
public EngineOptions onCreateEngineOptions() {
final Camera camera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);
return new EngineOptions(true, ScreenOrientation.LANDSCAPE_SENSOR,
new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), camera);
}
@Override
public void onCreateResources() throws IOException {
this.mHelloWorldTexture = new AssetBitmapTexture(this.getTextureManager(),
this.getAssets(), "helloworld.png");
this.mHelloWorldTextureRegion = TextureRegionFactory.extractFromTexture(
this.mHelloWorldTexture);
this.mHelloWorldTexture.load();
}
@Override
public Scene onCreateScene() {
this.mEngine.registerUpdateHandler(new FPSLogger());
final Scene scene = new Scene();
scene.getBackground().setColor(Color.YELLOW);
final float centerX = CAMERA_WIDTH / 2;
final float centerY = CAMERA_HEIGHT / 2;
final Sprite sprite = new Sprite(centerX, centerY,
this.mHelloWorldTextureRegion, this.getVertexBufferObjectManager());
scene.attachChild(sprite);
return scene;
}
}
here is the logcat:
