Android游戏没有运行。未知的logcat

Question

这是我的代码：

package com.example.juggler;

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.scene.background.Background;
import org.andengine.entity.sprite.Sprite;
import org.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlas;
import org.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlasTextureRegionFactory;
import org.andengine.opengl.texture.region.ITextureRegion;
import org.andengine.ui.activity.BaseGameActivity;

public class GameActivity extends BaseGameActivity {

    Scene scene;
    protected static final int CAMERA_WIDTH = 480;
    protected static final int CAMERA_HEIGHT = 800;
    BitmapTextureAtlas ballTexture;
    ITextureRegion ballTextureRegion;

    @Override
    public EngineOptions onCreateEngineOptions() {
        // TODO Auto-generated method stub
        Camera mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);
        EngineOptions options = new EngineOptions(true,
                ScreenOrientation.PORTRAIT_FIXED, new RatioResolutionPolicy(
                        CAMERA_WIDTH, CAMERA_HEIGHT), mCamera);
        return options;
    }

    @Override
    public void onCreateResources(
            OnCreateResourcesCallback pOnCreateResourcesCallback)
            throws Exception {
        // TODO Auto-generated method stub
        loadGfx();

        pOnCreateResourcesCallback.onCreateResourcesFinished();

    }

    private void loadGfx() {
        // TODO Auto-generated method stub
        BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");

        // width and height power of 2^x
        ballTexture = new BitmapTextureAtlas(getTextureManager(), 32, 32);
        ballTextureRegion = BitmapTextureAtlasTextureRegionFactory
                .createFromAsset(ballTexture, this, "ball.png", 0, 0);
        ballTexture.load();
    }

    @Override
    public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback)
            throws Exception {
        // TODO Auto-generated method stub
        this.scene = new Scene();
        this.scene.setBackground(new Background(0, 125, 58));
        pOnCreateSceneCallback.onCreateSceneFinished(this.scene);
    }

    @Override
    public void onPopulateScene(Scene pScene,
            OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception {
        // TODO Auto-generated method stub

        Sprite sBall = new Sprite(CAMERA_WIDTH / 2, CAMERA_HEIGHT / 2,
                ballTextureRegion, this.mEngine.getVertexBufferObjectManager());

        this.scene.attachChild(sBall);
        pOnPopulateSceneCallback.onPopulateSceneFinished();

    }

}

这是日志：

我不明白问题是什么，我正在使用AndEngine。我不认为问题出在代码中，有什么建议吗？当我运行该程序时，该程序只是没有运行，它说要强行关闭。

谢谢，我认为它会自动改变，但事实并非如此。但现在我遇到了另一个问题。

我的新日志说明了这一点：
