Android SDK 1.5 "--core-library" build error问题解决方法

如果你手工配置build path，把SDK1.5的android.jar加入到某些工程中，你可能会遇到下面的编译错误：

> Attempt to include a core VM class in something other than a core
> library.
> It is likely that you have attempted to include the core library from
> a desktop
> virtual machine into an application, which will most assuredly not
> work. If
> you really intend to build a core library -- which is only appropriate
> as
> part of creating a full virtual machine binary, as opposed to
> compiling an
> application -- then use the "--core-library" option to suppress this
> error
> message. If you go ahead and use "--core-library" but are in fact
> building
> an application, then please be aware that your build will still fail
> at some
> point; you will simply be denied the pleasure of reading this helpful
> error
> message.
>

这意味着你想把一个桌面VM中的类运用到android应用程序中，比如java.awt.*, java.swing.*, java.bean等。

可用android包参见：available packages on Android，这肯定是不行的。

为了解决这个问题，需要修改工程目录下的.classpath文件，把其中的path设置成下面的值即可：

<classpathentry kind="con"
path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>
