我开始使用 AndEngine 并尝试加载纹理以在屏幕中制作精灵。在我的活动课上，我有
public EngineOptions onCreateEngineOptions() {
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
CAMERA_WIDTH = dm.widthPixels;
CAMERA_HEIGHT = dm.heightPixels;
float screenResolutionRatio = ((float)CAMERA_WIDTH/(float)CAMERA_HEIGHT);
this.mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);
final EngineOptions options = new EngineOptions(true,
ScreenOrientation.PORTRAIT_FIXED,
new RatioResolutionPolicy(screenResolutionRatio),
this.mCamera);
return options;
}
public void onCreateResources(OnCreateResourcesCallback arg0)
throws Exception {
mTextures = new NTTextures(this);
}
NTTexture 是一个加载纹理的类。
这是代码中有意义的部分：
public NTTextures(final BaseGameActivity activity) {
try
{
BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");
this.spritesheetTexturePack = new TexturePackLoader(activity.getAssets(), activity.getTextureManager()).loadFromAsset("gfx/baseAtlas.xml", "gfx/");
this.mSpritesheetTexture = spritesheetTexturePack.getTexture();
this.mSpritesheetTexturePackTextureRegionLibrary = spritesheetTexturePack.getTexturePackTextureRegionLibrary();
this.ping= this.mSpritesheetTexturePackTextureRegionLibrary.get(baseAtlas.PING_ID);
activity.getEngine().getTextureManager().loadTexture(this.mSpritesheetTexture);
} catch (final TexturePackParseException e) {
Log.e("Error", String.valueOf(e));
}
}
所以，所有这一切都完成了，我有一个错误日志和崩溃。

我用 Android 2.2 测试 LG Optimus One，所以我认为我的设备不需要 GLES 库。这是错误的原因还是我的代码中有错误？另外，是否有 AndEngine 支持的设备列表？
另外： 我检查了测试过的手机规格——它具有支持 OpenGLES 2.0 的 Adreno 200。所以，它一定需要库，但它不需要。有什么建议么？
