execute dex: wrapper was not properly loaded first的处理方法

开发Android应用，SDK下载了2.3.3和2.2版本的，
新建一个工程使用2.2的SDK,工程上有红叉，不知道少了什么，
运行时报错 Your project contains error(s),please fix them before running your application.
控制台显示：[2011-02-15 11:00:33 - Dex Loader] Unable to execute dex: wrapper was not properly loaded first
[2011-02-15 11:00:33 - HellWorld] Conversion to Dalvik format failed: Unable to execute dex: wrapper was not properly loaded first

处理方法：
找到Eclipse目录下eclipse.ini文件，将最后两句改为
-Xms128m
-Xmx512m
重启eclipse
然后project->clean一下就OK了
