eclipse android程序运行报错:Conversion to Dalvik format failed: Unable to execute dex:

[2013-06-19 16:59:01 - Dex Loader] Unable to execute dex: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

[2013-06-19 16:59:01 - AndroidTable] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

最后解决方法:

我的程序在根目录的libs文件夹中包含了两个jar的包,原因就是这两个包有内容重复或冲突之类的吧(我是这么理解的)

删除一个不需要用的包就可以,我删除了android.support.v4的那个jar

再启动程序就可以了
