我開始使用AndEngine並嘗試加載紋理以在屏幕中生成精靈。 在我的活動我班有AndEngine支持的設備
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就是紋理被裝載的類。
這裏是代碼的meaningfull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));
}
}
這樣，那麼這一切後，我有一個錯誤日誌等和崩潰。

我用於測試LG Optimus One與Android 2.2，所以我認爲我的設備沒有需要的GLES庫。這是錯誤的原因還是我的代碼中有錯誤？另外，有沒有AndEngine支持的設備列表？
此外： 我檢查了測試的手機規格 - 它有Adreno 200支持OpenGLES 2.0。所以，它一定需要庫，但它不需要。有什麼建議麼？
這就是我需要的！ – 2012-07-26 12:12:16
