AndEngine sprite causing a force close - andengine

Question

first time poster, new to Android programming. Using Eclipse classic, have android SDK loaded and the API. Have created a hello world app, and the text send app that follows (android dev site). Now working on a game using the Jimmaru (http://jimmaru.wordpress.com/2011/09/28/andengine-simple-android-game-tutorial/) tutorial (GLES1), using AndEngine (GLES1 as far as I can tell, didn't have a superclass of "simpleBaseGameActivity" when I looked for it. I've gotten the blank screen to show up fine, but the step to add a player sprite results in a force close on app execution/loading.
Here is my One Class (SimpleGame)
package com.example.game;
import org.anddev.andengine.engine.Engine;
import org.anddev.andengine.engine.camera.Camera;
import org.anddev.andengine.engine.options.EngineOptions;
import org.anddev.andengine.engine.options.EngineOptions.ScreenOrientation;
import org.anddev.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;
import org.anddev.andengine.entity.scene.Scene;
import org.anddev.andengine.entity.scene.background.ColorBackground;
import org.anddev.andengine.entity.sprite.Sprite;
import org.anddev.andengine.entity.util.FPSLogger;
import org.anddev.andengine.opengl.texture.TextureOptions;
import org.anddev.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlas;
import org.anddev.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlasTextureRegionFactory;
import org.anddev.andengine.opengl.texture.region.TextureRegion;
import org.anddev.andengine.ui.activity.BaseGameActivity;
import android.view.Display;
public class SimpleGame extends BaseGameActivity {
// initiates view
private Camera mCamera;
// Main Scene
private Scene mMainScene;
private Sprite player;
// Textures
private BitmapTextureAtlas mBitmapTextureAtlas;
private TextureRegion mPlayerTextureRegion;
#Override
public Engine onLoadEngine() {
final Display display = getWindowManager().getDefaultDisplay();
int cameraWidth = display.getWidth();
int cameraHeight = display.getHeight();
mCamera = new Camera(0, 0, cameraWidth, cameraHeight);
return new Engine(new EngineOptions(true, ScreenOrientation.LANDSCAPE,
new RatioResolutionPolicy(cameraWidth, cameraHeight), mCamera));
}
#Override
public void onLoadResources() {
// This places player character on screen, file is in
// assets/gfx/Player.png
mBitmapTextureAtlas = new BitmapTextureAtlas(512, 512,
TextureOptions.BILINEAR_PREMULTIPLYALPHA);
BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");
mPlayerTextureRegion = BitmapTextureAtlasTextureRegionFactory
.createFromAsset(this.mBitmapTextureAtlas, this, "Player.png",
0, 0);
mEngine.getTextureManager().loadTexture(mBitmapTextureAtlas);
}
#Override
public Scene onLoadScene() {
mEngine.registerUpdateHandler(new FPSLogger());
mMainScene = new Scene();
mMainScene
.setBackground(new ColorBackground(0.09804f, 0.6274f, 0.8784f));
mMainScene.attachChild(player);
final int PlayerX = this.mPlayerTextureRegion.getWidth() / 2;
final int PlayerY = (int) ((mCamera.getHeight() - mPlayerTextureRegion
.getHeight()) / 2);
player = new Sprite(PlayerX, PlayerY, mPlayerTextureRegion);
return mMainScene;
}
#Override
public void onLoadComplete() {
// TODO Auto-generated method stub
}
}
Here is my AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Any help is much appreciated, thank you.

Answer 1

move this line
mMainScene.attachChild(player);
to a point in between these two lines
player = new Sprite(PlayerX, PlayerY, mPlayerTextureRegion);
return mMainScene;
