1.AndEngine介绍（百度百科）

2.下载git工具

 a.下载git for windows版(这个客户端)

b.下载windows install安装服务包()，在博客附件中(xp版的，其他版本可找TortoiseGit for windows 安装提示)，提供，也可以去微软下载

c.下载客户端操作工具TortoiseGit for windows

3.下载AndEngineExamples源码

下面列出编译必须扩展，在AndEngineExamples工程

  下载引用源码

去代码库

4.编译AndEngineExamples源码

有编译错误

解决错误：

Description Resource Path Location Type
DrawMode cannot be resolved to a variable HullAlgorithmExample.java /AndEngineExamples/src/org/andengine/examples line 168 Java Problem
引入 这个import org.andengine.entity.primitive.DrawMode;

Description Resource Path Location Type
The constructor TextOptions(AutoWrap, float, float, HorizontalAlign) is undefined TextBreakExample.java /AndEngineExamples/src/org/andengine/examples line 106 Java Problem
注释的为报错的

//this.mText = new Text(50, 40, this.mFont, "", 1000, new TextOptions(AutoWrap.LETTERS, AUTOWRAP_WIDTH, Text.LEADING_DEFAULT, HorizontalAlign.CENTER), vertexBufferObjectManager);
  this.mText = new Text(50, 40, this.mFont, "", 1000, new TextOptions(AutoWrap.LETTERS, AUTOWRAP_WIDTH,  HorizontalAlign.CENTER, Text.LEADING_DEFAULT), vertexBufferObjectManager);  
 

Description Resource Path Location Type
Type mismatch: cannot convert from void to AnimatedSprite BoundCameraExample.java /AndEngineExamples/src/org/andengine/examples line 220 Java Problem

注释的为报错的
//final AnimatedSprite face = new AnimatedSprite(pX, pY, this.mBoxFaceTextureRegion, this.getVertexBufferObjectManager()).animate(100);
  final AnimatedSprite face = new AnimatedSprite(pX, pY, this.mBoxFaceTextureRegion, this.getVertexBufferObjectManager()); 
  face.animate(100);

Description Resource Path Location Type
Type mismatch: cannot convert from void to AnimatedSprite SplitScreenExample.java /AndEngineExamples/src/org/andengine/examples line 179 Java Problem

注释的为报错的
//final AnimatedSprite face = new AnimatedSprite(pX, pY, this.mBoxFaceTextureRegion, this.getVertexBufferObjectManager()).animate(100);
  final AnimatedSprite face = new AnimatedSprite(pX, pY, this.mBoxFaceTextureRegion, this.getVertexBufferObjectManager()); 
  face.animate(100);

编译通过啦

我们都知道BitmapFactory类提供几种解码方法 （decodeByteArray()、 decodeFile()、 decodeResource()等） 从各种来源中创建一个Bitmap。选择最合适的解码方法基于您的图像数据源。这些方法尝试为构造位图分配内存，因此可以很容易有OutOfMemory异常的结果。

java.lang.OutofMemoryError: bitmap size exceeds VM budget.这种蛋疼的问题是因为CCD对每个android应用有内存限制16M，现在放宽了，但是如果把十几兆的图片直接显示出来那肯定是要挂滴。
怎么办咧？压缩小了的显示吧。

BitmapFactory.Options是关键

具体的做法是用两次解码！
第一次解码，其目的是测量尺寸，如果oom了也没关系
然后计算压缩比例
第二次解码，变小了
public static int calculateInSampleSize(
            BitmapFactory.Options options, int reqWidth, int reqHeight) {
    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        // Calculate ratios of height and width to requested height and width
        final int heightRatio = Math.round((float) height / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value, this will guarantee
        // a final image with both dimensions larger than or equal to the
        // requested height and width.
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
    }

    return inSampleSize;
}

注：inSampleSize值是2 的幂。
inJustDecodeBounds设置为true

public static Bitmap decodeSampledBitmapFromResource(Resources res, int resId,
        int reqWidth, int reqHeight) {
    Bitmap bm = null;
    // First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    try {
        BitmapFactory.decodeResource(res, resId, options);
    } catch (OutOfMemoryError e) {
        System.gc();
    }

    // Calculate inSampleSize
    options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);

    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    try {
        bm = BitmapFactory.decodeResource(res, resId, options);
    } catch (OutOfMemoryError e) {
         System.gc();
    }
    return bm;
}

这种方法容易地将任意大小的位图加载到显示 100 x 100 像素的缩略图，如下面的代码示例所示：
mImageView.setImageBitmap(
    decodeSampledBitmapFromResource(getResources(), R.id.myimage, 100, 100));
