Question

我开始使用AndEngine并尝试加载纹理以在屏幕中制作精灵。在我的活动课中我有

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。

以下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。

我用于测试LG Optimus One和Android 2.2，所以我认为我的设备没有需要GLES lib。这是错误的原因还是我的代码中有错误？另外，AndEngine是否有任何支持的设备列表？

增加： 我检查了测试的手机规格 - 它有Adreno 200支持OpenGLES 2.0。所以，它必须有必要的库，但事实并非如此。有什么建议吗？

Answer 1

要确保部署因设备上的OpenGL版本错误而失败，您可以在清单文件中插入以下行：

<uses-feature android:glEsVersion="0x00020000" />

Eclipse不允许您在不支持OpenGL ES 2.0的设备上部署应用程序。此外，这也会阻止使用旧设备的用户从Google Play下载您的应用程序。希望这会有所帮助。

Answer 2

您可以尝试以下方法：AndEngine.isDeviceSupported()

AndEngine支持的设备
