Question

I am starting to use AndEngine and trying to load a texture to make a sprite in a screen.
In my activity class I have

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 is a class where textures are loaded.

Here is the meaningfull part of the code:

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));
        }

      }

So, then all this done, I have an error log like and a crash.

I use for tests LG Optimus One with Android 2.2, so I supposed that my device has no needed GLES lib. Is that the reason of the errors or I have bugs in my code? Also, are there any list of supported devices for AndEngine?

Addition:
I checked tested phone specs – it has Adreno 200 with OpenGLES 2.0 support. So, it must have needed libs, but it doesn’t. Any suggestions?

Answer 1

You can try this method: AndEngine.isDeviceSupported()
