Background AndEngine

Question

I recently started working on AndEngine. It is difficult to find up-to-date documentation / help material in this regard. I am trying to set a background image after going through examples and source code. But for some reason, the screen remains blank. I can not find any useful information related to this. Here is the code:

public class AndEngineActivity extends BaseGameActivity { private static final int CAMERA_WIDTH = 720; private static final int CAMERA_HEIGHT = 480; private Camera mCamera; private TextureRegion mBgTexture; private BitmapTextureAtlas mBackgroundTexture; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } @Override public Engine onLoadEngine() { // TODO Auto-generated method stub this.mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT); return new Engine(new EngineOptions(true, ScreenOrientation.LANDSCAPE, new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), this.mCamera)); } @Override public void onLoadResources() { // TODO Auto-generated method stub BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/"); this.mBackgroundTexture = new BitmapTextureAtlas(1024, 1024, TextureOptions.DEFAULT); mBgTexture = BitmapTextureAtlasTextureRegionFactory.createFromAsset(this.mBackgroundTexture, this, "background.png", 0, 0); this.mEngine.getTextureManager().loadTextures(this.mBackgroundTexture); } @Override public Scene onLoadScene() { this.mEngine.registerUpdateHandler(new FPSLogger()); final Scene scene = new Scene(); final int centerX = (CAMERA_WIDTH - mBgTexture.getWidth()) / 2; final int centerY = (CAMERA_HEIGHT - mBgTexture.getHeight()) / 2; SpriteBackground bg = new SpriteBackground(new Sprite(centerX, centerY, mBgTexture)); scene.setBackground(bg); return scene; } @Override public void onLoadComplete() { // TODO Auto-generated method stub } } 

Answer 1

you need to remove:

 /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } 

Answer 2

Use the following:

CCSprite background=CCSprite.sprite("car7m.jpg" );

Answer 3

Instead

  SpriteBackground bg = new SpriteBackground( ... ); scene.setBackground(bg); 

to try

  Sprite bg = new Sprite(new Sprite(centerX, centerY, mBgTexture)); scene.attachChild(bg);
