Question

我刚从AndEngine主页复制了一个示例，但应用程序总是被迫在模拟器中停止:(（请帮助我。这是主要的活动：

    public class HelloMe extends BaseGameActivity {

   private static final int CAMERA_WIDTH = 720;

   private static final int CAMERA_HEIGHT = 480;

  // ===========================================================
  // Fields
  // ===========================================================

   private Camera mCamera;
   private BitmapTextureAtlas mFontTexture;
   private Font mFont;

@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
    this.mFontTexture = new BitmapTextureAtlas(256, 256, TextureOptions.BILINEAR_PREMULTIPLYALPHA);

    this.mFont = new Font(this.mFontTexture, Typeface.create(Typeface.DEFAULT, Typeface.BOLD), 32, true, Color.BLACK);

    this.mEngine.getTextureManager().loadTexture(this.mFontTexture);
    this.getFontManager().loadFont(this.mFont);

}

@Override
public Scene onLoadScene() {

    this.mEngine.registerUpdateHandler(new FPSLogger());

    final Scene scene = new Scene();
    scene.setBackground(new ColorBackground(0.09804f, 0.6274f, 0.8784f));

    final Text textCenter = new Text(100, 60, this.mFont, "Hello AndEngine!\nYou can even   have multilined text!", HorizontalAlign.CENTER);
    final Text textLeft = new Text(100, 200, this.mFont, "Also left aligned!\nLorem ipsum dolor sit amat...", HorizontalAlign.LEFT);
    final Text textRight = new Text(100, 340, this.mFont, "And right aligned!\nLorem ipsum dolor sit amat...", HorizontalAlign.RIGHT);

    scene.attachChild(textCenter);
    scene.attachChild(textLeft);
    scene.attachChild(textRight);

    return scene;
}

@Override
public void onLoadComplete() {
    // TODO Auto-generated method stub

}

}

清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.hello"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="15" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".HelloMe"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
     </activity>
 </application>

</manifest>

我使用的是Android 4.0.3，并且andengine.jar已添加到Build Path中。 AndEngine可以只运行Android 2.2吗？提前感谢：D。

PS：这是堆栈跟踪：

Answer 1

AndEngine，你使用的版本看起来不像最新版本，不支持模拟器。尝试插入手机并运行它，它可能会工作。

Answer 2

添加“libs”文件夹并复制andengine.jar并编译。

AndEngine：示例不起作用
